Semi-Precision

/ / / Semi-Precision

Semi-Precision bearings have machined metal raceways with tighter tolerances than unground bearings. They include ball retainers which keep the balls separated and evenly spaced. This prevents the balls from colliding with each other and causing damage. It also evenly distributes the load around the whole of the bearing. This makes them capable of higher speeds, higher load capacities, and longer life then unground bearings. The raceways can be made from mild steel, stainless steel, or even polypropylene. All bearings in this category are pressed into tubes and can be replaced.
