WHY SOME BEARINGS RARELY FAIL In the good old days, most serviceable wheel bearings were maintained at least every 25,000 to 30,000 miles during a brake job. During this process, races, stub-axles and cages could be inspected and repacked. New bearing sets cost less than $10. Today, the average life

Storage time refers to the time during which the bearing can be stored without adversely affecting its running performance. WKT bearings are coated with high-quality anti-rust oil to protect them from corrosion. Long-term storage can be achieved if the bearing is placed in the original unopened and

Thrust ball bearings are designed to withstand thrust loads at high speeds, and are composed of washer-shaped ferrules with ball rolling grooves. Because the ring is in the shape of a cushion, thrust ball bearings are divided into two types: flat base cushion type and self-aligning spherical cushion
