Thrust Roller Bearings
Available with cylindrical, tapered, and spherical rollers, thrust roller bearings sustain only axial loads. NSK’s thrust roller bearings are suitable for heavy loads and offer high axial rigidity. Machined brass cages are used as standard.
Thrust tapered roller bearings come in two types: the TT type, which has a flange on the housing washer (outer ring), and the TTF type, which does not. The TT type is suitable when it can be securely fixed in the radial direction, while the TTF type tolerates slight misalignment that occurs between the shaft and housing during operation.
Thrust spherical roller bearings contain convex rollers that make them self-aligning and unaffected by mounting error and shaft deflection. The E-type offers a high load capacity design with a pressed steel cage.
