B7212-E-T-P4S-UL

The B7212-E-T-P4S-UL is a high-precision single-row angular contact ball bearing engineered specifically for demanding machine tool spindles where uncompromising rotational accuracy and stability are vital. Featuring a 25-degree contact angle designated by the "E" suffix, the B7212-E-T-P4S-UL delivers an optimized balance of radial and axial load-carrying capacity, making it exceptionally reliable under heavy cutting forces. The integration of a textile laminated phenolic resin cage, guided by the outer ring, minimizes friction and heat generation, which allows the assembly to maintain smooth operation at high operational speeds. Furthermore, the B7212-E-T-P4S-UL adheres to the ultra-strict P4S tolerance class, combining standard ISO 4 boundary dimensions with the superior running accuracy of ISO 2 to eliminate mechanical runout. Supplied with a universal configuration and a light preload ("UL"), this bearing gives engineers the flexibility to arrange multiple units in various mounting combinations while ensuring consistent system rigidity and prolonged service life.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
