The SRG Bearing Company is proud to announce the new Lightning Bearing Technology (LBT) line of ceramic motorcycle wheel bearings. Ceramic by its nature is lighter than steel by about 2/3 the weight; it is harder than steel when it is in ball form and it is virtually frictionless because it is non-porous. A ceramic hybrid bearing has steel races with ceramic balls and a full ceramic bearing has ceramic races and balls. Full ceramic and ceramic hybrid wheel bearings are particularly well suited to both competitive and recreational motorcycle applications.
The Boca Bearing Company have been an industry leader in ceramic bearing technology for over 15 years. Reducing rolling resistance and conserving energy has been our hallmark. We offer a full line of full ceramic & ceramic hybrid bearings specifically suited to Motorcycles. Various ABEC tolerances, radial plays, retainer styles and seal/shield configurations are available. To make things easier for you we have compiled bearing kits and listed them according to the manufacturer and model of the motorcycle wheel that the bearings will fit.

   Ceramic Lightning Yellow Seal Motorcycle Wheel Bearing Kits are specially designed for off-road or excessively dirty operating environments. These bearings are maintenance free and lubed for life. The heavy duty rubber seal provides extra protection against the harshest elements. Ceramic Lightning bearings have ceramic balls, with stainless steel races and retainers. Ceramic hybrids are lighter, capable of achieving higher RPM’s and sustaining higher operating temperatures than traditional bearings. Bearings that are packed in grease will require a short break in period to loosen up. Grease can usually be removed before shipping upon request. Please contact Boca Bearings directly before installing ceramic bearings in a motorcycle engine.

   Timing
   Wheel bearings should be checked on a regular schedule. The motorcycle manual will outline recommendations particular to the motorcycle model. If you hear a grinding noise coming from the wheel or the wheel wobbles, this is a good indication that you should check the wheel bearings.

   Check Wheel Bearings
The bike should be placed on stand so that the wheels are off the ground. Make sure the bike is securely placed on the stand and cannot fall off. According to The Bearing Shop website, there is a three-step process to check wheel bearings: (1) Spin the wheels to ensure they spin freely; (2) Firmly grab the top and bottom of a wheel and try to rock it back and forth; (3) Turn the wheel to a 90-degree angle and do the same.
