Welcome to Linqing Xinshengdi Bearing Co., Ltd.
ZARF2575 TV High-Rigidity Combined Bearing
- Superior Thermal Stability: The TV cage withstands continuous high-speed operation without losing structural integrity or degrading grease.
- Massive Thrust Capacity: Thickened cylindrical thrust rollers easily handle the heavy feed forces generated during deep-cut machining.
- Vibration Damping: The heavy outer ring and polymer cage work in tandem to suppress chatter, improving the machined surface finish of the workpiece.
- Pre-Drilled Flange: Ready for immediate, rigid integration directly into machine castings.

Product Introduction
The ZARF2575 TV represents the pinnacle of precision engineering in ball screw support systems. Identical in critical dimensions (25 x 75 x 50 mm) to the TN variant, this bearing utilizes a TV-designated glass-fiber reinforced polymer cage, prized for its superior thermal stability and centrifugal force resistance. The combination of a thick-walled outer ring, high-precision radial needle rollers, and dual axial cylindrical roller thrust stages allows this bearing to absorb massive multi-directional shock loads without deflection. Through rigorous metallurgical control and sub-micron grinding techniques, the ZARF2575 TV provides global B2B clients with the ultimate solution for heavy-duty, high-accuracy rotational control.
Applications
Large-scale CNC gantry milling machines.
High-speed automation transfer lines.
Precision medical scanning equipment positioning systems.
FAQ
Q: Can this bearing handle high RPMs?
