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. 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.
đź’ˇ Que signifie ABEC-7?
ABEC-7 est une classification de haute précision du Comité des ingénieurs en roulements annulaires (ABEC), indiquant des tolérances de fabrication extrêmement strictes. Ces roulements offrent des performances ultra-lisses et à faible friction et sont souvent utilisés dans des applications à grande vitesse et haute précision.
Les roulements ABEC-7 se retrouvent couramment dans les instruments de précision, les équipements aérospatiaux, les moteurs électriques haut de gamme et les machines industrielles exigeantes. Ils offrent des performances exceptionnelles, mais sont généralement plus coûteux en raison du niveau de précision impliqué.
