Ball bearing at the heart of almost every product with rotating shaft. Most bearing specifications and manufacturing tolerances are quantified in one-ten thousands of an inch (1/10,000) by ABMA; every manufacturing process 100% checked and feedback provided to ensure the integrity of the process and product.
Predictable uniformity, or repeatability, in the manufacturing process is crucial to ensuring consistent bearing performance. If variations occur in the manufacturing process from part to part, the production line may make bearings that fall within the complete spectrum of the allowable tolerance standards. That inconsistency producing parts that go from one end of the range to the other can lead in turn to variations in the performance of each bearings, either individually or from lot to lot. The narrower the variation in each step of the manufacturing process, the greater the consistency of each bearing's performance.
