RHP 7020CTDUHP4 super precision angular contact ball bearing. Series: 7000. Bore: 100 mm. Outside Diameter: 150 mm. Width: 24 mm. Contact Angle: 15°. Single row, open, universally ground and matchable. Also written 7020-C-T-DUH-P4, 7020C T DUH P4 and 7020CTDUH P4.
C: 15° contact angle. T: machined laminated phenolic cage, outer ring land riding, rated to 120 °C. DUH: duplex pair, universally ground, heavy preload. P4: EP7, equivalent to ABEC 7. Fafnir cross designation 2MM9120WICRDUH carries the same 15° angle and phenolic outer land riding cage.
Basic Dynamic Load Rating: 95.0 kN per bearing. Basic Static Load Rating: 77.0 kN per bearing. Permissible Axial Load: 49.0 kN. A 15° contact angle favours speed and radial stiffness, which is why it is the standard choice for machine tool spindle front and rear positions. Limiting speed runs to 9,200 rpm on grease and 14,000 rpm on oil or oil-air lubrication. The phenolic cage is light and self lubricating and holds ball guidance steady to 120 °C.
Heavy preload, 2,572 N across a back-to-back or face-to-face pair, giving 264 N/µm axial rigidity and 60 µm measured axial clearance. Effective Load Center a: 28.7 mm. Heavy preload buys the highest axial and radial stiffness in the range and the tightest shaft location, at the cost of more heat generation than a light or medium set.
Two bearings, supplied as a universally ground duplex pair at heavy preload. Universally ground rings mount back-to-back, face-to-face or in tandem, with the preload set by the ground ring faces.
Diameter of Shaft Abutment, da min: 109 mm. Diameter of Housing Abutment, Da max: 141 mm and Db max: 144 mm. Radius of Shaft or Housing Fillet, ra max: 1.5 mm, rb max: 0.8 mm. Bearing chamfer r min: 1.5 mm, r1 min: 1 mm. Recommended grease quantity: 6.7 g per bearing.
ISO base number 7020. Direct equivalents at the same 15° angle, P4 class and heavy preload: NSK 7020CTRDUHP4, SKF 7020 CD/P4ADGC, FAG B7020-C-T-P4S-DUH, Fafnir 2MM9120WICRDUH.
