B71930-C-T-P4S-UL

Engineered specifically for machine tool main spindles and demanding manufacturing equipment, the FAG B71930-C-T-P4S-UL is a high-precision, single-row angular contact ball bearing built to deliver minimal runout and exceptional structural rigidity. With its standard 150mm bore, 210mm outer diameter, and 28mm width, this component utilizes a sharp 15-degree contact angle to seamlessly manage combined radial and axial loads at high rotational speeds. A defining mechanical feature of the B71930-C-T-P4S-UL is its premium P4S tolerance class-which outclasses standard ABEC-7 dimensional specs and pushes running accuracy up to P2 limits-working alongside an outer-ring-guided, laminated fabric cage designed for long-term stability at operating temperatures up to 100°C. Because the B71930-C-T-P4S-UL is manufactured in a universally matchable design with a light preload, it gives engineers maximum layout flexibility to arrange the bearings in pairs or complex sets, ultimately optimizing dynamic load ratings up to 125,000 N and extending the service life of heavy-duty machinery. For systems requiring uncompromised precision and reliable high-speed performance under load, the B71930-C-T-P4S-UL remains a trusted industry choice.

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