7009CYDUP4 Nachi high precision Angular pair of Ball Bearings with 15 degrees contact angle and Polyamide resin cage, pair of ball bearings is 2 duplex bearings, bearings are ABEC-7 (P4) quality and made in Japan.
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.
