Basic bearing cross-reference information.

Glossary

  • Cylindrical roller thrust bearings (TMP) - These are thrust bearings containing cylindrical rollers. They can sustain only axial loads, but they are suitable for heavy loads and have high axial rigidity. The cages are machined brass.
  • Tapered roller thrust bearings (TT, TTF or V-Flat) - These are thrust bearings containing tapered rollers. TT-type bearings, which have a rib on the housing washer, can accurately guide the shaft in the radial direction. TTF-type bearings, which have no rib on the housing washer, can tolerate some eccentricity during operation.
  • The ball thrust bearings are designed to handle thrust loads while operating at high speeds. These bearings can be ordered with an aligning seat and aligning washer if misalignment or deflection can not be avoided.
  • The spherical thrust bearings are designed to handle very heavy thrust loads in one direction while operating at low to moderate speeds. The design of the spherical thrust will also allow for some radial load while thrust load is imposed. The spherical shape of the outer ring raceway makes these bearings excellent for handling misalignment.
