RHP7011CTP0Angular Contact Ball Bearing – 55 mm ID, 90 mm OD, 18 mm Width, Open, 15° Contact Angle, Phenolic Cage, EP1 Class

Product Description

What this part is

RHP 7011CTP0 single-row angular contact ball bearing. Series: 70. Bore: 55 mm. Outside diameter: 90 mm. Width: 18 mm. Contact angle: 15°. Closure: open. Cage: machined laminated phenolic, outer-ring land riding. Precision class: P0, RHP EP1, ABEC 1.

Decoding the designation

7011: 70-series angular contact ball bearing, 55 mm bore. C: 15° contact angle. T: machined laminated phenolic cage, outer-ring guided, rated to 120 °C. P0: RHP EP1 precision, ABEC 1. The carton also carries the RHP B-series form B7011X2TAEP1, where X2 is the same 15° contact angle and EP1 the same precision class.

Load ratings

Basic dynamic load rating Cr: 43.0 kN. Basic static load rating C0r: 28.6 kN. Permissible axial load Pa: 18.9 kN. Effective load centre a: 18.7 mm. Calculation factor f0: 15.5. Mass: 0.380 kg. Recommended grease quantity: 2.2 g.

What these specs mean in practice

A 15° contact angle is the high-speed, lower-thrust end of the angular contact range: it accepts higher speeds and less axial load than a 25° or 40° bearing on the same 55 x 90 x 18 mm envelope. The phenolic cage rides on the outer ring land, which keeps the cage centred by the raceway rather than the balls and cuts cage-to-ball friction at speed. Phenolic runs to 120 °C and absorbs oil, so it carries lubricant into the ball track.
