7313BMU Nachi Angular Ball Bearing,
bearing is 40 Contact Angle, Brass Cage and Flush
Ground, Made in Japan, inner diameter is 65mm, outer
diameter is 140mm and width is 33mm.
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. Single-row Angular Contact ball
bearings can sustain radial, axial or composite loads, however,
any axial load must be in one direction. This bearing type is
generally used in pairs to handle the induced load resulting from
the internal axial force generated by the applied radial load.
When mounting two single bearings in adjacent positions, NACHI
provides these combination parts (pairs) with preadjusted
clearance. Paired combination bearings are matched sets.
Combination or paired bearings can be arranged BACK-TO-BACK (DB),
FACE-TOFACE (DF), or in TANDEM (DT). DB or DF sets can sustain
bidirectional axial loads.
