Type TVL ball thrust bearings provide exceptionally low friction, cool running and quiet operation at high speeds and also are less sensitive to misalignment. TVLs are designed for thrust loading, but will also accommodate some radial loading.

Size range: 228.6 mm to 1371.6 mm (9 in. to 54 in.)

Design Attributes

• Precision ground and lapped steel balls are enclosed by hardened and ground steel races and separated by a bronze cage.
• Other materials may be specified as required to suit specific application needs.

Applications 

• Fluid control valves
• Machine tool tables and spindles
• Oil and gas rotary tables

The TVL type ball thrust bearing consists of a larger ring (identified as the outer ring) and a smaller ring (identified as the inner ring). The inner ring is usually the rotating element and is shaft mounted.  The outer ring is typically stationary and should be mounted with an outside diameter clearance that allows the bearing to assume a normal operating position.

• If combined loads are expected, the outer ring must be radially located in the housing.
• TVL type bearings should always be operated under thrust loading. If a constant thrust load is not normally present, it should be imposed by springs or other devices.
