B7038-E-T-P4S-UL

When repairing or upgrading high-speed machine tools like CNC lathes and milling machines, the main spindle's precision dictates the entire machine's accuracy, which is why the B7038-E-T-P4S-UL is such a common choice for these rebuilds. Measuring 190x290x46mm, this single-row angular contact ball bearing combines solid rings, large steel balls, and a tough laminated fabric cage to support high load capacities while keeping the assembly incredibly rigid. Machinists rely on the B7038-E-T-P4S-UL mainly due to its P4S tolerance class-a rating that actually exceeds standard P4 limits to guarantee extremely tight guidance and low vibration even when the spindle is running at high speeds. Because it features a 25-degree contact angle and a universal design configured for light preload, you can easily install the B7038-E-T-P4S-UL in tandem, back-to-back, or face-to-face arrangements to handle whatever specific axial and radial load directions your equipment requires.

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