Tapered Roller Thrust Bearing T1421 with Cage And I.D. Corner Reliefs

T1421-902A1 Tapered roller thrust bearings are designed to accommodate heavy axial loads and peak loads. The bearings are very stiff and require little axial space.

Thrust roller bearings are used to bear the combined axial and radial load with the main axial load, but the radial load shall not exceed 55% of the axial load. The design of this type of bearing with the main axial load coincides with that The main bearings are complementary and use the same type of roller design.

Tapered roller bearing, thrust tapered roller bearing

Tapered roller thrust bearings are designed to accommodate heavy axial loads and peak loads. The bearings are very stiff and require little axial space.

Tapered roller thrust bearings in the following basic and application-specific designs:

· single direction tapered roller thrust bearings

· double direction tapered roller thrust bearings

· screw-down bearings

Features and benefits

• Separable design
  The shaft and housing washers and the roller and cage thrust assemblies of tapered roller thrust bearings with cages can be mounted separately.

• Low friction
  The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear.

• Long service life
  Depending on the design, crowned or logarithmic raceway profiles optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment compared with conventional straight raceway profiles.

• Enhanced operational reliability
  The surface finish on the contact surfaces on the rollers and raceways supports the formation of a hydrodynamic lubricant film.

• High load carrying capacity
  The rollers incorporated in TKW tapered roller thrust bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution and enables the bearings to accommodate heavy axial loads.
