NSK thrust ball bearings

NSK single-direction thrust ball bearings are comprised of two bearing washers (a shaft washer and a housing washer) and a single cage containing the balls. They can sustain axial loads in one direction.

Features

• Specialized design
  A cage contains the balls while the grooved aligning seat washer guides them.
• Dedicated components
  Washers attached to the shaft are called “shaft washers” and those attached to the housing are called “housing washers” (fixed rings).
• Support axial loads
  Single-direction thrust ball bearings can take axial loads in one direction.

Applications
Printer peripheral equipment, ball screw support sections of precision positioning stages, automatic guided vehicles (AGVs), radial drilling machines, fishing reels

NSK double-direction thrust ball bearings use three washers, with two cages containing the balls. This shaft washer is sandwiched between the two cages, allowing the bearing to take axial loads in both directions.

Features

• Specialized design
  A cage contains the balls while the grooved aligning seat washer guides them.
• Dedicated components
  Washers attached to the shaft are called “shaft washers” and those attached to the housing are called “housing washers”.
• Support axial loads in both directions
  True to their name, double-direction thrust ball bearings can sustain axial loads in both directions. Models with aligning seat washers are alaso available to help reduce the effects of mounting errors.

Applications
Vacuum pumps, disc hubs in agricultural machinery, compressors, press machines, clutch breakers
