The raceways of both the inner and outer rings of this set up kind are made out of a set contact angle. These claws are non-separable. A larger quantity of balls may be installed than in the event of Deep-groove ball bearings, Because the balls are added using construction. Standard cage substances may be brushed steel, high-strength brass, or resin. Cage material is dependent on the bearing service or series and requirement. Single-row Angular Contact ball bearings can sustain loads, however, any axial load must be in 1 direction. This posture type is typically used to handle the triggered load caused by the internal force generated by the applied radial load. When mounting two single bearings in adjacent places, NACHI supplies these combination parts (pairs) with pre-adjusted clearance. Paired mix bearings are matched places. Combination or paired bearings could be ordered BACK-TO-BACK (DB), FACE-TO-FACE (DF), or in TANDEM (DT). DB or DF sets could maintain loads that are bidirectional.
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.
