The raceways of both the inner and outer rings of this bearing type are made with a set contact angle. These bearings are non-separable. Since the balls are inserted utilizing counter-bore construction, a larger number of balls can be installed than in the case of Deep-groove ball bearings. Standard cage materials may be pressed steel, high-strength brass, or synthetic resin. Cage material is dependent on the bearing series and or service condition.
💡 What Does ABEC-7 Mean?
ABEC-7 is a high-precision rating from the Annular Bearing Engineers’ Committee (ABEC), indicating extremely tight manufacturing tolerances. These bearings provide ultra-smooth, low-friction performance and are often used in high-speed, high-accuracy applications.
ABEC-7 bearings are commonly found in precision instruments, aerospace equipment, high-end electric motors, and demanding industrial machinery. They offer exceptional performance but are typically more expensive due to the level of accuracy involved.
