ABEC-3 |
OEM Replacement. Best economical cost vs durability. Use for riding conditions that warrant frequent bearing replacement. |
||||
Angular Contact |
Best all-around bearing. Good mix of low cost, durability and performance. |
||||
ABEC-5 |
Better than OEM quality. |
||||
Ceramic Hybrid |
Fast bearing. Increased durability. Higher cost. |
||||
ZERO Ceramic |
Fastest bearing, least amount of drag. Lighter seals require more frequent service. Best used as a "race day" bearing. |
* Expected life of bottom bracket bearings depends on many factors. Wheels Mfg BB bearings require maintenance and replacement once worn. Moisture, dirt or other contamination inclusion in bearings are not covered under WARRANTY.
Angular Contact bearings are specifically designed for hubs, bottom brackets and headsets. In standard radial bearings, only 3 or 4 balls make contact with the inner and outer race during the load, at any given time. In angular contact bearings, each ball inside the bearing is in contact with both the inner and outer race at all times. This spreads both radial and axial forces over a larger surface area, decreasing friction, and minimizing wear. Angular contact bearings are direction-specific, installed with the red seal facing outwards, and require 3-5Nm of pre-load on the inner race.
Generally, the higher the ABEC number, the higher the quality of the bearing. An ABEC rating is based on many measurements of a bearing, including the tolerances of the inner and outer races, the roundness of the balls, how true the races are, surface finish and noise of the bearing at high RPMs. Enduro angular contact, ceramic hybrid and ZERØ Ceramic bearings are all ABEC-5 rated.
Enduro ceramic hybrid and ZERØ Ceramic bearings have ceramic balls with steel races.
