Product Description

What this part is:

FAG B7016CB.TPA.P4.UL super-precision spindle bearing (angular contact ball bearing), universal ground for light preload. Bore Diameter: 80 mm. Outside Diameter: 125 mm. Overall Width: 22 mm. Contact Angle: 15°. Preload: Light (354 N). Precision Class: ABEC 7 / P4. Current Schaeffler designation: B7016-C-T-P4S-UL.

Decoding the designation:

B70 — FAG spindle bearing, ISO dimension series 10.

16 — bore code, 16 x 5 = 80 mm.

C — 15° contact angle, for high speed and radial stiffness.

TPA — fabric-base laminated phenolic cage.

P4 — ISO tolerance class P4, equivalent to ABEC 7.

UL — universal design, light preload when mounted in any O, X or tandem arrangement.
