FAGB7208-C-TPA-P4-ULSuper-Precision Angular Contact Ball Bearing – 40 mm Bore, 80 mm OD, 18 mm Width, 15° Contact Angle, P4 Class, Light Preload

Product Description

What this part is:

FAG super-precision single-row angular contact ball bearing, 40 mm bore, 80 mm outside diameter, 18 mm width. Open, straight bore, phenolic laminate cage, P4 tolerance class, universally ground for light preload. The carton and ring carry two designations for the same bearing: 7208-TG-P4 in the older FAG scheme, B7208-C-TPA-P4-UL in the current Schaeffler scheme. Single bearing. Unit Quantity: 1 Pc.

Decoding the designation:

72 — ISO dimension series.

08 — bore code, 40 mm bore.

B — super-precision spindle-bearing execution.

C — 15° contact angle.

TG and TPA — fabric-base phenolic laminate cage.

P4 — tolerance class, equivalent to ABEC 7.

UL — universal grinding with light preload: two bearings of this designation mounted back-to-back or face-to-face produce a defined light preload with no shimming, and any number can be stacked in tandem.

Compatibility and replacement:

SKF 7208 CD/P4A — 15°, P4A class. NSK 7208CTYNSULP4 — polyamide cage, not phenolic. Timken 2MM208WI — 15°, P4 class. A 7208 in an A, A5, B or E execution carries a different contact angle, and a 7208 at P5 or P0 is a different tolerance class. Part number variants: 7208TGP4, 7208-TG-P4, 7208 TG P4, B7208-C-TPA-P4-UL, B7208C.TPA.P4.UL, B7208CTPAP4UL, B-7208-C-TPA-P4-UL, 7208C, 7208.

Frequently asked questions:

What is the contact angle of the FAG 7208TGP4?

Contact Angle: 15°, from the C in the B7208-C-TPA-P4-UL designation.

What does UL mean?

UL is universal grinding with light preload, so two bearings of this designation produce a defined light preload when mounted back-to-back or face-to-face.

What cage does it have?

A fabric-base phenolic laminate cage, designated TG or TPA.
