RHP7015CTSULP0Angular Contact Ball Bearing 75x115x20 mm 15° Contact Angle Light Preload Universally Faced

Product Description

What this part is

RHP 7015CTSULP0 single-row angular contact ball bearing. Bore: 75 mm. Outside Diameter: 115 mm. Overall Width: 20 mm. Contact Angle: 15°. Precision Class: P0 (ISO Normal tolerance class); RHP class code EP1. Cage Material: laminated phenolic resin. Cage Type: machined, outer-ring guided. Closure Type: open on both faces. Snap Ring Included: No. Bore Type: straight. Rolling Elements: carbon chrome bearing steel balls. Bearing Material: carbon chrome bearing steel, BS970 534A99/535A99 or SAE 52100. Series: RHP 70, ISO dimension series 10. Number Of Rows: 1. Base Number: 7015. The ring faces are universally ground, so one piece pairs with any other bearing of the same designation in a back-to-back, face-to-face or tandem stack and reaches the light preload value when the rings are clamped solid.

Decoding the designation

Type 7: single-row angular contact ball bearing. Dimension series 0: ISO series 10. Bore code 15: 75 mm bore. Contact angle C: 15°. Cage T: laminated phenolic resin, outer ring guided. Grouping SU: single universal face control. Preload L: light. Precision grade P0: ISO Normal tolerance class, RHP class code EP1. The carton alternate B7015X2TULEP1 gives the same reading in the RHP B-series scheme, X2 being 15° and EP1 the Normal class.

Load ratings and speed

Dynamic Load Rating (Cr): 48.0 kN (48,000 N). Static Load Rating (C0r): 45.5 kN (45,500 N). Limiting Speed: 18,100 rpm oil/air; 11,100 rpm grease. Lubricant: oil/air or grease. Maximum Operating Temperature: 120 °C.

Preload and stiffness

Preload: Light (L). Axial Preload, light grade, as a paired set: 290 N. Axial Stiffness, light grade, as a paired set: 92 N/µm. The bearing is preload-set at manufacture rather than clearance-set.

What these specs mean in practice

The 15° contact angle favours speed over thrust, carrying higher surface speed and greater radial load than the 25° execution of the same envelope, and less axial load.

Universal face control makes the preload a property of the pair rather than of a shim stack. The inner and outer rings are the same width and the face positions are set at manufacture, so clamping two bearings of this designation together produces the L preload directly, back-to-back or face-to-face. Mounted in tandem they share load equally.

The laminated phenolic resin cage adds low mass and holds an oil film well against the balls.

A single-row angular contact ball bearing carries thrust in one direction. Axial load in the opposite direction is taken by a second bearing opposing this one, or by another element in the shaft stack.

Interchange guidance

7015C is the ISO base designation for a 15° angular contact bearing on this envelope, and the RHP carton alternate is B7015X2TULEP1. The NSK equivalent on the same tolerance class is 7015CTRSULP0. Same-envelope bearings with a different contact angle, preload grade or tolerance class — 7015A5 at 25°, the medium and heavy preload grades, and the tighter tolerance classes — are related sizes rather than equivalents. A universally faced single also differs from a duplex-ground pair, since DU pieces are ground as a set.
