Product Description

What this part is

FAG B7010C.T.P4S.UL is a super-precision spindle angular contact ball bearing. Bore Diameter: 50 mm. Outside Diameter: 80 mm. Overall Width: 16 mm. Contact Angle: 15°. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Bearing Material: Chrome steel. Item Weight: 0.25 kg (0.55 lb).

Decoding the designation

B70 — Schaeffler’s spindle bearing series, a light 70-section angular contact ball bearing built to super-precision tolerances for machine tool spindles.

7010 — ISO size code. Bore 50 mm, outside diameter 80 mm, width 16 mm.

C — Contact angle 15°. The shallow angle favours speed and radial stiffness.

T — Fabric-base laminate phenolic cage, machined. Phenolic runs light and damps well, which is what allows the high speed ratings.

P4S — Precision Class: ABEC 7 / P4, with the running accuracy of the S execution.

UL — Universally matchable. Faces are ground so any two or more bearings pair in back-to-back, face-to-face or tandem arrangement and reach the published preload without shims.

What these specs mean in practice

Dynamic Load Rating: 29,000 N. Static Load Rating: 16,100 N. Limiting Speed: 18,000 rpm grease; 28,000 rpm oil. Fatigue load limit, radial: 1,710 N.

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

A 15° contact angle carries more radial load and runs faster than a 25° execution of the same size; a 25° bearing carries more thrust and runs slower. Series: B70. Base Number: B7010.

Mounting data

Preload per matched pair: light 148 N, medium 493 N, heavy 994 N. Axial rigidity per matched pair: 52 N/µm light, 91 N/µm medium, 130 N/µm heavy. Shaft shoulder diameter 56 mm. Outer ring shoulder diameter 74 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.

Interchange guidance

Same-envelope, same-angle, same-class equivalents: SKF 7010 CD/P4A, NSK 7010C, NTN 7010C, Timken Fafnir 2MM9110WI, RHP 7010CT and Koyo 7010C. The Fafnir 2MM prefix is the 15° super-precision code, and the 9110WI number maps to ISO 7010.
