 Introduction of CZPT single row ball slewing bearings

LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball bearings, roller bearings and precision bearings as per customer’s different technical requirements.
Slewing bearing is also called slewing ring, slewing ring bearing, turntable bearing, and rotary bearing.
The single row ball slewing ring bearing is composed of 2 seat-rings. The balls contact with the circular race at 4 points, via which the axial force, radial force and resultant moment may be born simultaneously.

Structure:
Single row ball slewing bearing has 3 different types:
Single row ball slewing bearing with no gear
Single row ball slewing bearing with external gear
Single row ball slewing bearing with internal gear

LYHY Production Process

Quality Control Process of CZPT slewing bearings

LYHY Slewing Bearing Packing

And then packed with kraft paper and professional belts;
At last, with wooden box totally at the outer packing to invoid the rust or the moist;
We can depend on the customers  demand to be packed;

INSTALLATION OF CZPT SLEWING BEARINGS

Preparation:
Make sure that the model is correct and slewing bearing isn’t damaged during transportation.
2.  Check the appearance and rotational state of the bearing, such as rotational precision clearance, rotating flexibility, seals position, lubrication grease etc.
3.  The installation datum plane and bracket installing plane should be clean, grease, burr, paint and other foreign body should be wiped off.

Installation:

1. The screws in the installing plane should be fit with the mounting holes in the slewing bearing
2.  The slewing bearing has a soft zone marked with an “s” on the upper surface, when installing the bearing, it is important to ensure that this area is placed in a non-load or infrequent load zone.
3.  When the bearing is placed on the supporting frame work it is important to check the interface between these 2 surfaces. This check should be carried out with the insertion of feel gauges between the 2 surfaces. If a gap should exist then it is recommended to plane/resurface the effective area so as to remove the gap.
4.  Install slewing bearing with high strength screws, and choose appropriate strength bolts. All bolts are required to be tightened evenly. The sequence of this tightening process is shown in Pic. Welding of bearing is not allowed, in the event of welding any adjacent parts, heat transfer shall be avoided so as to cause the bearing to become deformed or change the hardness.
5.  After installation, the bearing should be rotated to check for smooth operation and any emission of unusual noise. If either of the aforementioned are noted, then the bearing should be adjusted to eliminate them. The teeth of the largest run-out are coated with green paint.

Understanding the Different Types of Bearings

When you are looking for a bearing, you have many options to choose from. This article will explain the various types, functions, and working principles of different types of bearings. Once you understand the basic components, you can make an informed decision about which one to buy. Here’s an overview of some of the most common types. Learn more about each type below! Read on to learn about the differences between these different types of bearings! Posted in Articles

Functions

bearing
Bearings serve as an integral part of a mechanical device. These devices help transfer torque from one part of a structure to another. These mechanisms increase the efficiency of a shaft by increasing its life. However, the functions of bearings depend on the application of the structure. Among other functions, bearings provide support to shafts. Anti-friction bearings come in two types: ball and roller bearings. These components have line and point contact, which is the most common type. Archimedes’s principle states that the force is equal to the weight of the fluid that is being displaced. Bearings can transfer lateral loads to a substructure.
A bearing has two primary functions. The first is to prevent direct metal-to-metal contact. A bearing prevents friction, heat generation, and wear and tear of components. A bearing also reduces energy consumption. Its other purpose is to guide and support a rotating body. In addition to these functions, bearings can also reduce wear and tear on a machine. As a result, they are among the most widely used machines in the world.
Seals are a major component of a bearing. They prevent foreign materials from entering and lubricating the moving parts. The design of seal lips determines their effectiveness. Fuel economy regulations and CO2 emissions regulations are pushing the demand for low-friction bearings. However, high-performance seals do not always provide high-performance. As a result, current estimations of the friction in bearings depend on trial and error methods.
Another important function of bearings is that they transfer the load of a rotating component to its housing. This load can be axial or radial. Bearings also limit movement to predefined directions. Some types of rolling element bearings have balls or cylinders inside. These bearings are less frictional than sliding ones, thus they allow parts to move freely during rotation. These parts can then be used for various applications. So, bearings are an integral part of machines.

Types

The most common type of bearing is a plain bearing. It uses surfaces in rubbing contact to transmit movement from one part to another. These bearings may be discrete or may consist of a hole in a metal sleeve or a planar surface bearing another part. Some plain bearings are flanged, while others are made of a sleeve with a flange at one end. These bearings often give acceptable accuracy and life, but they are expensive and cannot be used in large scale applications.
Radial bearings are used when there is a need for high-speed or corrosive parts. This type of bearing also serves as a support in an intermediate situation. Its two components are called the base and the cover. The base and cover are connected and are arranged parallel to the main axis. This type of bearing is used in steady-state and axial motion applications. The radial bearings are also used when the shafts are long.
Angular contact bearings are another type of bearing. These are easy to install and require minimal maintenance. Their races are displaced along the axis. They are also better at handling axial loads and transferring them to the housing. These types of bearings are commonly used in pumps, automobiles, and high-speed applications. If you are looking for an affordable, reliable bearing, look no further than the angular contact bearing.
Another type of bearing is a self-lubricating bushing. These are lightweight and wear-resistant. Unlike the other types of bearing, they do not require any lubrication or maintenance. In fact, some are completely maintenance-free. But if you’re worried about maintenance, this type of bearing may be a good choice. There are many benefits of using self-lubricating bushings. It is also a good option for applications where your machine is exposed to extreme temperatures.

Working principle

bearing
A bearing has two primary functions: support and load transfer. In engineering applications, the bearing tends to push the load in the direction of the shaft. A radial load pushes the bearing downward and a thrust load pushes it sideways. Both types of load transfer are important in a variety of applications. The working principle of each type is described below. Listed below are the main uses for each type of bearing.
A plain bearing uses a PTFE liner on the interface of two moving parts. The PTFE liner acts as a lubricant and may be filtered to alter its friction. The journal bearing uses the motion of the journal to force fluid into the gap between two moving parts. This results in a small amount of play in the bearing. This play is acceptable for most applications. A ball bearing may have a maximum play of 2 mm for a ten-millimeter shaft.
The primary function of a bearing is to assist in rotation and to reduce mechanical friction between the two objects. A bearing may be installed as a separate device or as an integral part of a machine. For more complex applications, bearings are very precise components requiring the highest standards of technology. For this reason, it is important to understand the working principle of bearings. The next time you need to lift or slide a heavy object, consider a bearing.
Ball bearings are a common type of ball bearing and can be found in industrial machinery and automobiles. Their unique structure helps them support less weight. This is because they are comprised of two rings – an inner race and an outer race. The balls themselves have a small area of contact and transfer axial loads in one direction. A cage surrounds the balls and prevents them from colliding. This makes ball bearings a popular choice for many applications.

Sealing system

A bearing’s seals are vital for the operation of rolling and rotating components. These systems enable rotation and linear movement while limiting friction and dispersing stress. Without the proper seals, these components could face catastrophic failure. In addition to protecting the bearing from external forces, seals help retain lubricant inside the system and prevent harmful particles from entering the gap. A seal’s lubrication helps prevent the onset of mechanical damage and prolongs the life of the bearing.
A bearing seal is made up of two parts: the inner sealing element and the outer sealing element. A passageway runs through the bearing assembly to the outer seal element. A hydraulic press or pneumatic jack is recommended for installing the seal. These tools are effective in reducing deformation and improving seal installation quality. When fitting the seal, ensure that the tool does not hit the seal directly. A proper adopter will distribute the load uniformly across the seal.
The seal’s efficiency depends on its gap. A four-inch shaft seal can flow 0.5 standard cubic feet per minute. A seal’s efficiency is highly dependent on the gap size. The gap size is a cube of the flow through the system. A smaller gap size allows high flow and pressure but less leakage. If both surfaces of the seal have similar pressures and flow rates, the seal is efficient. However, a small gap reduces the pressures and reduces wear.
Mechanical seals have numerous advantages, including their ability to protect against contaminants and splashing liquids. Labyrinth seals are the first line of defense against leaks. They operate without friction. Their high level of sealing efficiency helps ensure that the bearing remains operational for long. This type of seal is made from metal plates and is designed for a wide temperature range and misalignment. Its advantages include being easy to install and offering 100% sealing efficiency.

Maintenance

Bearing maintenance is critical to ensuring that your bearings keep operating at their peak performance. Proper maintenance will improve bearing life, reduce downtime and increase productivity while reducing costs. Here is an 8-point checklist to optimize your bearings and make them last longer. To optimize their performance, you should follow these steps regularly. In case a bearing does not last long, you should replace it as soon as possible. Listed below are some tips to ensure proper maintenance.
The first step is to determine how often your bearings require lubrication. Some manufacturers recommend that you lubricate them weekly, but this can do more harm than good. Instead, use ultrasound to measure the level of friction and trend its levels. This way, you will know exactly when to grease your bearings. It’s also important to check how often they should be inspected and calibrated. A professional can provide guidance on proper maintenance.
Next, inspect your bearings for cracks and scratches. You should never install a bearing that has been dropped or scratched. Even a small crack will affect the performance of the bearing and could lead to its premature failure. A proper alignment is essential for the bearing to function properly. Make sure you have the correct tools to perform this task. These tools can help you reduce manual work and promote safe bearing maintenance. You should also ensure that the shaft and housing are clean and undamaged.
Proper maintenance can prolong bearing service life. Proper lubrication, mounting, inspection, basic condition monitoring, and dismounting can extend their life. Proper maintenance extends their lifespan and improves plant productivity. While bearings are essential for machinery, you should make sure you follow the proper safety procedures every time you work with them. These tips will also help prevent accidents and maintain your machine’s efficiency. Once you’ve followed these guidelines, you can safely inspect your bearings and ensure that they’re operating at their optimum capacity.
