7009CYDUP4 Nachi Angular Contact Bearing 45x75x16mm ABEC-7 Bearing

The raceways of both the outer and inner rings of this set up kind are made out of a contact angle that was set. These bearings are non-separable. A number of balls can be installed than in the instance of ball bearings, Considering that the balls are added utilizing counter-bore structure. Standard cage substances could possibly be brushed on high-strength metal, steel artificial or resin. Cage substance depends upon the bearing support or series and requirement. Single-row Angular Contact ball bearings can sustain loads, however, any axial load must be in 1 direction. This bearing type is normally utilized to deal with the load caused by the axial force generated by the radial load that was applied. When mounting two bearings in adjacent positions, NACHI provides these mix components (pairs) with pre-adjusted clearance. Mix bearings are matched sets. Combination or paired bearings could be arranged BACK-TO-BACK (DB), FACE-TO-FACE (DF), or at TANDEM (DT). Bidirectional axial loads can be sustained by DF or DB sets.

💡 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.
