16381001 Slewing Bearing Turntable Bearing for Radar

The TR Series consists of three-row roller bearings which offer the highest capacity for a given diameter. When an XR or DT Series bearing doesn’t meet the stiffness and capacity requirements, consider the TR Series.

Design Features 

The bearing has three independent rows of rollers oriented normal to the direction of loads being transmitted through the bearing. Their orientation is selected to optimize capacity, provide low frictional resistance and minimize deflection.

The top and bottom rows of rollers transmit any opposing thrust loads and combine to transmit any moment loading, while the middle row transmits any radial loads. The rollers, the separator configuration used for each and the mating raceways are sized to meet load or other application requirements. In order to obtain these performance benefits, the supporting structures must satisfy higher stiffness and lower flatness requirements than those for similar sized XT or DT Series bearings. Gear teeth or other drive mechanisms can be provided on the inner or outer support ring, and the choice of hole pattern can be added for bearing retention.

Applications 

TR Series bearings have been used successfully in heavy duty applications requiring extra stiffness and capacity including: 

❚ Radar ❚ Cranes ❚ Mining shovels ❚ Stackers and reclaimers ❚ Heavy mill equipment ❚ Tunnel boring machines
