High-speed stability: The angular contact design and precision machining (radial runout ≤ 5 μm) enable a maximum operating speed of 18,000 rpm (grease lubrication), significantly higher than that of similarly sized deep groove ball bearings.
Excellent sealing: The 2RZ seal ring is made of nitrile rubber and tightly integrated with a metal skeleton, achieving an IP54 protection rating (resistant to splashing water and dust).
Composite load-bearing capacity: It can withstand both radial loads (basic rated dynamic radial load of 3.6 kN) and unidirectional axial loads (basic rated dynamic axial load of 2.1 kN), making it suitable for transmission structures subjected to both radial and axial forces (such as lead screws, spindles, etc.).

| Dust will have a bad effect on the bearing, so keep the surrounding clean. | Strong impact during use can easily cause scratches and indentations. | Avoid replacing existing tools, and use appropriate tools. | Bearings are precision parts, so hot installation is recommended. | Sweat on your hands during operation will cause rust, so it is best to wear gloves. |
