RHP 7218CTDULP4 super precision angular contact ball bearing. Bore: 90 mm. Outside Diameter: 160 mm. Width: 30 mm per bearing. Series: 72, medium section. Single row of balls per bearing, open on both faces. Rolling Elements: chrome steel balls.
Contact Angle: 15°. Cage: machined laminated phenolic, outer-ring guided. Preload: light. Precision Class: P4, equal to ABEC 7 and to RHP class EP7. Configuration: duplex, universally ground. The same bearing is designated 7218-C-T-DUL-P4, B7218X2TDULEP7, 2MM218WI-CR-DUL and 218HDL.
A 15° contact angle favours speed and radial stiffness over thrust capacity. The 72 medium section carries a higher load than a 70 light-section bearing on the same bore. Dynamic Load Rating: 114 kN. Static Load Rating: 91.5 kN. Light preload gives the coolest running and the highest speed of the three preload grades. P4 tolerance holds bore, outside diameter and running accuracy to super precision limits.
Unit Quantity: 2 Pcs. Universally ground faces allow the pair to be mounted back-to-back, face-to-face or in tandem, and the ground offsets set the preload when the rings are clamped. Total width of the pair: 60 mm.
Preloaded sets are supplied without internal clearance, so Internal Clearance is N/A. Clamping is against the ground faces of both rings. Phenolic cages are rated to 120 °C.
Same-spec equivalents at 15°, P4, light preload: Fafnir 2MM218WI-CR-DUL, NSK 7218CTRDULP4, FAG B7218C.T.P4S.UL. Related size: SKF 7218 CD/P4ADGA, same envelope and angle, SKF light-preload universal matching. Related size: 7218A5 at 25°, same envelope, different thrust and speed capability.
