B71920-E-T-P4S-UL

The B71920-E-T-P4S-UL is a high-precision angular contact spindle bearing designed specifically for the spindles of high-speed CNC machine tools, offering exceptional rigidity and smooth operational performance. It features an inner diameter of 100 mm, an outer diameter of 140 mm, and a width of 20 mm. With a contact angle of 25 degrees, the bearing utilizes an outer-ring-guided laminated fabric cage (T) and adheres to the P4S ultra-high precision tolerance class-a standard that exceeds ISO P4 requirements. Thanks to its "universal matching" design and light preload (UL) configuration, the B71920-E-T-P4S-UL can be flexibly arranged and installed according to specific application needs. When subjected to significant combined radial and axial loads, the bearing ensures minimal heat generation and superior rotational accuracy, while also delivering a long service life.

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