Heavy Duty Wheel Bearings Coast to Coast™ heavy duty wheel bearings are manufactured at factories that have ISO/TS 16949:2002 certified quality management systems. OEM customers of these factories include many of the largest US axle and trailer manufacturers.

The factories start with bearing quality steel and forge & roll the steel into rings. The rings are then turned to the shape and size of the raceways of the bearing cone and cup. After the turning process, the rings are heat treated and quenched in a continuous atmosphere controlled furnace and then annealed to a hardness of 59 to 64 HRC.

After heat treatment, the rings are machined to meet ABMA and other industry standard specifications.

All raceways and rollers are super finished to insure

smooth and quite operation while in service. All

bearing components are then cleaned and

protected with a rust inhibitor after final assembly.

While the bearings are being manufactured the

components are sample inspected after each

manufacturing process to insure they meet all

dimensional and visual specifications. The bearings

then go through a 100% final inspection before they

are packaged to leave the factory assuring

customers the highest level of quality.
