NSK HUB 1 wheel bearings, hub unit bearings

For HUB 1, NSK uses proprietary bearing-type designations such as "BWD" for ball bearings and "KWD" for tapered roller bearings. The HUB 1 NSK wheel bearings units are double-row angular contact ball bearings (BWD) and double-row tapered roller bearings (KWD) with back-to-back duplex outer rings.

No preload a djustments (including dimensional adjustments by shims) are required on the assembly line. The initial axial clearance is properly pre-set for the preload to fall within the specified range after mounting. In addition, the integral seal eliminates the need for automotive makers to externally apply seals.

NSK uses bearing reference for hub unit bearings clarifying boundary dimensions, types, and specification codes. Below are examples of NSK bearing reference:

For example: 35 BWD 18

  • 35: bore diameter 35mm
  • BWD: HUB 1 ball bearings
  • 18: Serial No.
