Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Chrome steel. Item Weight: 0.62 kg (1.37 lb). GTIN: 4012801451048.

Decoding the designation

B70 — Schaeffler’s spindle bearing series in the light 70 section.

7015 — ISO size code. Bore 75 mm, outside diameter 115 mm, width 20 mm.

C — Contact angle 15°.

T — Fabric-base laminate phenolic cage, machined.

P4 — Precision Class: ABEC 7 / P4.

UM — Universally ground to the medium preload class. A pair reaches 911 N of preload on assembly, whatever the arrangement.

What these specs mean in practice

Dynamic Load Rating: 52,000 N. Static Load Rating: 32,500 N. Limiting Speed: 12,000 rpm grease; 19,000 rpm oil. Fatigue load limit, radial: 3,450 N.

Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Cage Type: Machined. Lubricant: grease or oil. Operating temperature range: -30 °C to +100 °C.

Medium preload sits between the light class, which favours speed, and the heavy class, which favours stiffness. On this size the axial rigidity of a pair runs 76 N/µm light, 130 N/µm medium and 186 N/µm heavy. Series: B70. Base Number: B7015.

Mounting data

Preload per matched pair: 911 N at the medium class. Shaft shoulder diameter 82 mm. Outer ring shoulder diameter 107 mm.

Mounting Arrangement: Universal — back-to-back (O), face-to-face (X) or tandem. Internal Clearance: N/A; the bearing is preload-adjusted rather than clearance-set.

Quantity and configuration

Unit Quantity: 1 Pc. Single bearing, universally ground, ready to be matched with further pieces of the same designation and preload class.

Interchange guidance

Same-envelope, same-angle, same-class equivalents at medium preload: SKF 7015 CD/P4ADGB, NSK 7015CDBC9, NTN 7015C and Timken Fafnir 2MM9115WI DUM. Preload class is part of the match: a light-preload pair of the same number is a related execution with lower axial stiffness.
