B7028-E-2RSD-T-P4S-UL

Designed specifically for high-speed machine tool spindles, the B7028-E-2RSD-T-P4S-UL super-precision angular contact ball bearing combines heavy load carrying capacity with exceptional running accuracy. Featuring a 25° contact angle and a light universal preload (UL), the B7028-E-2RSD-T-P4S-UL maintains rigid support under simultaneous radial and axial forces while preventing excessive heat buildup during sustained high-RPM operation. Its dual non-contact 2RSD rubber seals lock in factory grease and block workshop debris without adding operational drag or speed limitations. Built to P4S tolerance standards-which exceed standard ISO Class 4 precision limits-and equipped with an outer-ring-guided phenolic resin cage (T designation), the B7028-E-2RSD-T-P4S-UL delivers the strict runout control and smooth performance required in CNC milling heads, grinding machines, and precision lathe spindles.

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