Motorsport over the years has used a variety of bearings either ball or taper roller
bearings for use in the Wheel hubs. The most popular now are the Double row angular
contact ball bearings used in road cars, Designed into a bespoke hub. Others use the third
generation of bolt on bolt off units adapted to particular applications. Most popular
makes being SKF, NTN/SNR, FAG, Timken, NSK-RHP and Koyo.

As with Wheel bearings, a lot of the Clutch release bearings are derived from standard
road car Clutch bearings adapted for motorsport use. The majority of clutch bearings are
bespoke parts. Popular makes being NTN/SNR, SKF, NSK-RHP and Koyo.

Taper Roller bearings are used in a variety of places on a race car. Designed to take high
radial and axial loads, these are used in Wheel hubs, Gearbox, differentials and axles.

Popular makes being Timken, NTN/SNR, SKF and Koyo.

Applications for motorsport use are varied, from Wheel bearings, Gearbox and some
Suspension components.

Available in: Deep Groove, Angular contact and double row.

Needle roller bearings are another component widely used in motorsport, in applications
such as Gearbox, Steering, and Suspension.

Available as Drawn cup, needle roller cage, and combined needle roller thrust.

Oil seals are mainly used in wheel hub and gearbox applications. Available in a variety of
materials, the popular ones being Nitrile, Silicone, or Viton — the latter two used in
higher temperature applications.

Available with either a single lip or with an extra wiper lip.

Circlips are used mainly for the retention of either spherical bearings (the non-staking
type) or ball bearings. Available in Imperial or Metric for internal and external
applications.

Imperial half nuts available in either right or left-hand form.
