Timken NSK 628/9 Deep Groove Ball Bearing China Supplier

Optimal Performance in High-Speed, Low-Maintenance Environments

This bearing excels in applications requiring smooth rotation at speeds up to 15,000 RPM (depending on lubrication and load). Its deep groove design accommodates both radial and axial loads, making it suitable for compact installations where space is limited. Whether operating in clean factory environments or moderately dusty industrial settings, the Z-series vibration levels (Z1 to Z4) ensure stable performance with minimal noise output.

الميزات الهندسية الرئيسية التي تؤثر على الموثوقية

The bearing steel construction provides a surface hardness of HRC 58-62, ensuring resistance to wear and deformation under load. Precision ratings from P0 (standard) to P4 (high precision) allow you to match the bearing’s dimensional accuracy to your application requirements—critical for interchangeability in replacement scenarios. The low noise feature is achieved through tight control of raceway geometry and ball roundness, reducing vibration that can lead to premature fatigue. For applications where maintenance access is limited, the long-life design minimizes replacement frequency.
