Product Description

Tandem Thrust bearings are also known as “Multi-Stage cylindrical roller thrust bearings” . 

Tandem Thrust bearings are comprised of “stages” which include precision ground and matched thrust plates. These bearings also include compression sleeves separated by cylindrical roller assemblies. This design enables the Tandem Thrust bearings to provide a solution in a radial restricted envelope. The bearings are available in multiple stages, 2-8 to accommodate your design requirements. Depending on your preference, these bearings are available in a wide variety of sizes and options.

TandemThrust Bearings can receive heavy load in a limited space and support firmly in the direction of axis and last long with low frictional power. In addition, these bearings are moved by oil lubrication. Also thesetandem thrust bearings are used principally in gear boxes for single & twin screw extruders in the rubber and plastic industries.

1.Multi-stage cylindrical roller thrust bearing (basic type) adopts elastic spacer to connect the shaft washer,housing washer, roller and cage assembly.

The components of this Thrust Bearings are demountable. The user should assemble or dismount the bearing meticulously according to numeral order we provide.

2. Multi-stage cylindrical roller thrust bearing (shaft type) is made by penetrating an axis through theinner bore of basic type multi-stage cylindrical roller thrust bearing and fastening the bearing to the axis by locking collar. The components of this type of cylindrical roller thrust bearing are inseparable.

3. Multi-stage cylindrical roller thrust bearing (sleeve type) locking collar is made by covering a sleeveto the external of the basic type multi-stage cylindrical roller thrust bearing.It is also inseparable,and is assembled and disassembled as a whole.

Can you Explain the Concept of Axial and Radial Load Capacity in Slewing Bearings?

The axial and radial load capacities are fundamental parameters that define the ability of slewing bearings to withstand different types of loads along different directions. Here’s an explanation of these concepts:

  • Axial Load Capacity:

The axial load capacity of a slewing bearing refers to its ability to withstand loads that act parallel to the axis of rotation. In other words, it’s the maximum force that can be applied along the vertical or horizontal axis without causing significant deformation or failure of the bearing components.

For example, in applications where the bearing supports vertical loads like those encountered in cranes or excavators, the axial load capacity is crucial to ensure the stability and safety of the equipment. Slewing bearings designed for high axial load capacities have sturdy components and optimized raceway profiles to distribute the load evenly and prevent stress concentrations.

  • Radial Load Capacity:

The radial load capacity of a slewing bearing pertains to its ability to withstand loads that act perpendicular to the axis of rotation. These loads are directed toward or away from the center of the bearing. Radial loads can result from weight, force, or moments acting perpendicular to the axis of rotation.

For instance, in applications involving cantilevered structures, the radial load capacity is essential to support the bending moments and forces applied to the bearing. Slewing bearings with high radial load capacities are designed to handle these loads without excessive deformation, minimizing wear and maintaining operational integrity.

  • Combined Load Situations:

Real-world applications often involve combinations of axial and radial loads. Slewing bearings must be selected and designed to handle these combined loads effectively. Engineers consider both axial and radial load capacities to ensure that the bearing can safely operate under the expected loading conditions.

Manufacturers provide load rating charts and data that specify the maximum axial and radial loads a slewing bearing can handle. Engineers use this information to make informed decisions about bearing selection for various applications.

In summary, the axial and radial load capacities of slewing bearings are essential parameters that determine their ability to withstand specific types of loads in various directions. Proper consideration of these capacities ensures safe and reliable operation in diverse applications.

Can you Explain the Differences Between Single-Row and Double-Row Slewing Bearings?

Single-row and double-row slewing bearings are two common configurations with distinct characteristics. Here are the key differences between them:

  • Design:

A single-row slewing bearing consists of one row of rolling elements positioned between the inner and outer rings. In contrast, a double-row slewing bearing has two rows of rolling elements.

  • Load-Carrying Capacity:

Double-row slewing bearings generally have a higher load-carrying capacity compared to single-row bearings. The presence of two rows of rolling elements enables them to handle heavier axial, radial, and moment loads.

  • Stiffness:

Double-row bearings offer higher stiffness due to the additional row of rolling elements. This stiffness can be advantageous in applications where precise positioning and resistance to deflection are crucial.

  • Compactness:

Single-row slewing bearings are typically more compact and have a smaller profile compared to double-row bearings. This compact design can be advantageous in applications with limited space.

  • Cost:

Single-row slewing bearings are generally more cost-effective compared to double-row bearings. The increased complexity and higher load capacity of double-row bearings can result in higher manufacturing costs.

  • Applications:

Single-row slewing bearings are suitable for applications with moderate loads and rotational requirements, where compactness is important. Examples include small cranes, excavators, and material handling equipment. Double-row slewing bearings are often used in larger and heavier machinery, such as construction equipment, wind turbines, and heavy-duty cranes.

  • Performance Trade-offs:

While double-row bearings offer higher load capacity and stiffness, they may also introduce higher friction and slightly reduced rotational efficiency compared to single-row bearings due to the presence of additional rolling elements.

In summary, the choice between single-row and double-row slewing bearings depends on factors like load requirements, available space, and desired stiffness. Each configuration has its own advantages and trade-offs, allowing engineers to tailor their selection to the specific needs of the application.
