Product Description

What this part is:

FAG B7030-C-T-P4S-UL super-precision spindle bearing, legacy designation B7030C.TPA.P4S.UL (carton marking B-7030-C-TPA-P4-K5-UL). Single-row angular contact ball bearing, universally ground, Light preload, open. Bore Diameter: 150 mm. Outside Diameter: 225 mm. Width: 35 mm. Unit Quantity: 1 Pc.

Decoding the designation:

B70 — FAG spindle bearing, ISO dimension series 10 (70xx).

30 — bore code, 30 x 5 = 150 mm.

C — 15° contact angle, for high speed with moderate axial rigidity.

T / TPA — laminated fabric (phenolic) cage. TPA is the legacy code; the current Schaeffler designation uses T.

P4S — FAG tolerance class, tighter than ISO P4.

U — universal design. The bearing can be paired back-to-back, face-to-face or in tandem with any other U bearing of the same size.

L — Light preload.
