Product Description

What this part is

Consolidated (FAG designation) B7021C.TPA.P4S.UL single-row super-precision angular contact ball bearing, also marked 7021-TG and B-7021-C-A-P4-UL. Bore Diameter: 105 mm. Outside Diameter: 160 mm. Overall Width: 26 mm. Contact Angle: 15°. Cage Material: Phenolic. Cage Type: Machined. Precision Class: ABEC 7 / P4. Preload: Light (471 N). Closure Type: Open. Bore Type: Straight. Series: B70.

Decoding the designation

B7021 — ISO dimension series 10 angular contact (B70 range), bore code 21, 105 x 160 x 26 mm.

C — 15° contact angle.

TPA / TG — machined fabric-base laminate phenolic cage, outer-ring guided.

P4S — Schaeffler precision grade: P4 dimensional tolerances with tighter running accuracy. ABEC 7 body.

UL — universal design, light preload when mounted in any paired arrangement. Preload force: 471 N.

What these specs mean in practice

A 15° contact angle gives high radial stiffness and high speed capability with moderate axial capacity, the standard geometry for machine tool spindles. Universal flush-ground faces let the bearing pair back-to-back, face-to-face or in tandem with a defined light preload. The machined phenolic cage is light and runs with low friction at speed.
