RHPAngular Contact Ball Bearing – 60 mm ID, 95 mm OD, 18 mm Width, Open, 15° Contact Angle, Light Preload, Phenolic Cage, P6 / ABEC 3

Product Description

What this part is

A single RHP angular contact ball bearing in the ISO 7012 size. Bore: 60 mm. Outside Diameter: 95 mm. Width: 18 mm. Closure: Open. Bore type: Straight. Rolling elements: Ball. Contact Angle: 15°. Cage Type: one-piece machined, inner-ring centred. Cage Material: laminated phenolic resin. Preload: Light (L). Precision Class: P6 (ISO Class 6, ABEC 3, RHP class code EP3). Series: ISO series 10 (70xx). Bearing Material: carbon chrome bearing steel, BS970 534A99/535A99 or SAE 52100. Single row, universally ground so it can be matched with a like bearing.

Decoding the designation

7012 — ISO dimension series 10, bore code 12, giving 60 x 95 x 18 mm.

C — 15° contact angle.

TB — one-piece machined laminated phenolic cage, inner-ring centred.

SU — single universally ground, so any two pieces of this designation pair back-to-back, face-to-face or in tandem and reach the specified preload as ground.

L — light preload.

P6 — ISO Class 6, ABEC 3, RHP class code EP3. ABEC 5 is the P5 class.

Load ratings

Dynamic Load Rating Cr: 35.0 kN (35,000 N). Static Load Rating C0r: 30.5 kN (30,500 N). Maximum recommended operating temperature: 120 °C, set by the laminated phenolic cage. Lubricant: Grease or oil.

What these specs mean in practice

A 15° contact angle carries more radial load and runs faster than a 25° bearing of the same size, and carries correspondingly less thrust. Light preload removes internal play and fixes the contact angle while adding the least heat of the standard preload grades, which makes axial position and runout repeatable without penalising speed. P6 is a general-precision class that places this bearing in accurate machinery duty. At 18 mm wide on a 60 mm bore this is a slim-section bearing from ISO dimension series 10, specified where axial space in the housing is short.

Thrust direction

A single-row angular contact bearing carries radial load together with thrust in one direction. Axial location in both directions comes from mounting a second bearing opposed to this one.

Interchange guidance

RHP designations cross-reference directly to NSK, which acquired RHP and continued the numbering. The same-spec equivalent is NSK 7012CTRSULP6. The Fafnir-scheme form on the carton is 2M9112WI CR. Bearings sharing the 60 x 95 x 18 mm envelope with a 25° contact angle, a different preload grade, or a P4 or P5 class are related sizes rather than substitutions. Harmonization Code: 8482.10.50.68.
