Product Description

What this part is

FAG B7012C.TPA.P4S single-row super-precision spindle angular contact ball bearing. Series: B70. Bore: 60 mm. Outside diameter: 95 mm. Width: 18 mm. Contact Angle: 15°. Open on both faces. Country of origin: Germany. Searchable forms include B7012CTPAP4K5, B7012C-TPA-P4-K5 and B 7012 C TPA P4 K5.

Decoding the designation

B70: Schaeffler’s spindle bearing range. C: 15° contact angle, the high-speed execution. TPA: machined cage of fabric-base laminate phenolic. P4S: dimensional accuracy to P4 with running accuracy to P2, the class used for machine tool main spindles. K5 is carried as an order-code variant on this listing.

What these specs mean in practice

Dynamic Load Rating: 23.6 kN. Static Load Rating: 17.6 kN. Limiting Speed: 18,000 rpm. A 15° contact angle in the B70 range is the high-speed, lower-thrust choice: it keeps ball loading and heat generation down so the bearing holds accuracy at speed. A phenolic cage is light and self-lubricating, which is why it is specified where a spindle runs fast and accelerates hard.

Quantity and configuration

One bearing.

Fitting notes

Straight bore on a cylindrical shaft seat. Operating range: -30 °C to 120 °C. Running Accuracy: P4 on radial and axial runout.

Interchange guidance

Base number: B7012. SKF equivalent on the same envelope: 7012 CD/P4A. GMN equivalent: S6012 C TA A7. FAG B7012-C-T-P4S-UL is a universal-light-preload execution and B7012-C-2RSD-T-P4S-UL is the sealed version — both are related sizes on the same 60 x 95 x 18 mm envelope rather than direct substitutions.
