Flange Slewing Bearings
Slewing bearings series, flange on the outer wheel, so that axial positioning is simple. Bearing housing is no longer needed and becomes more economical. Steel balls with small outer diameter are used to obtain low friction torque, high rigidity and good rotation accuracy of bearings. The use of hollow shafts ensures weight and wiring space. Flange slewing bearings mainly bear radial loads, but can also bear both radial and axial loads.

Classification of Slewing Bearings:
According to the rolling element arrangement, slewing bearings can be generally divided into four-point contact ball slewing bearing, crossed roller slewing bearing, three-row roller slewing bearing, and so on. We will devote ourselves to satisfying customers’ demands as a slewing bearing supplier.
Applications of Slewing Bearings:
Slewing bearing has a unique structure that could handle an integrated load like the axle, radial, and overturning hurdle. It combines support, rotating, transmission, fixed, sealed, anti-corrosion, and other functions into one unit. They are widely used in lifting machinery, construction machinery, transmission machinery, mining and metallurgy machinery, medical equipment and radar, ship, wind power, and other industries.
How To Extend The Life Of Rotating Ring Bearings:
In heavy duty applications, premature failure of large diameter bearings is a common fate.
However,Regular maintenance can prevent 96% of rotary ring bearing failures. To maximize bearing life, follow these tips: raceway and gear lubrication, bolt torque inspection and seal inspection.
Most rotary bearing failures are due to lubrication problems, contamination, overload, improper fitting and mounting.
Have a preventative maintenance program that includes bearings, and be alert for these four warning signs of potential bearing problems.
1. Play on bearings
2. Grinding, cracking, or clicking sounds
3. Add torque or binding
4. Debris particles emerge from the seal
