FAGB71907-C-T-P4S-ULSuper-Precision Angular Contact Ball Bearing – 35 mm Bore, 55 mm OD, 10 mm Width, 15° Contact Angle, P4S Class, Light Preload

Product Description

What this part is:

A FAG super-precision single-row angular contact ball bearing, 35 mm bore, 55 mm outside diameter, 10 mm width. Open, straight bore, machined phenolic laminate cage, P4S tolerance class, universally ground for light preload. The same bearing is designated 71907-TG-P4 in the older FAG scheme and B71907-C-T-P4S-UL in the current Schaeffler scheme. Unit Quantity: 1 Pc.

Decoding the designation:

719 — ISO dimension series, the extra-light, narrow cross-section family.

07 — bore code for a 35 mm bore.

B — super-precision spindle-bearing execution.

C — 15° contact angle.

T and TG — machined phenolic laminate cage.

P4S — tolerance class, ABEC 7 dimensional limits with ABEC 9 running accuracy.

UL — universal grinding with light preload: two bearings of this designation come together back-to-back or face-to-face at a defined light preload with no shims or ground spacers, and any number can be stacked in tandem.

Compatibility and replacement:

Cross-references: Timken/Fafnir 2MM9307WI, the same 35 x 55 x 10 mm 15° super-precision envelope, its 2MM prefix denoting the 15° angle; NSK 7907CTYNSULP4 and SKF 71907 CD/P4A, the same series, angle and class. NSK designates this 35 x 55 x 10 mm size 7907.

Frequently asked questions:

What is the contact angle of the FAG 71907TGP4?

15°, from the C in B71907-C-T-P4S-UL.

What does UL mean?

Universal grinding with light preload, so two bearings of this designation pair back-to-back or face-to-face at a defined light preload.

What cage does it have?

A machined phenolic laminate cage.
