Bicycle Bearings | REDLINE, PROLINE DS - CRANKS
The Boca Bearing Company is proud to announce the new Lightning Bearing Technology (LBT) line of deep groove, ceramic bicycle bearings for hubs, bottom brackets, headsets and pivot points. 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. Miniature full ceramic and ceramic hybrid bearings are particularly well suited to both competitive and recreational bicycle applications.
The Boca Bearing Company have been an industry leader in ceramic bearing technology since 1987. Reducing rolling resistance and conserving energy has been our hallmark. We offer a full line of miniature, deep groove, standard, full ceramic & ceramic hybrid bearings specifically suited to bicycles. 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 bike component that the bearings will fit.
