Detailed Product Information
Design & Protection
The 626Z features the universal deep groove geometry, capable of supporting significant radial loads and moderate axial loads from both directions. The single, non-contact steel shield is an effective solution for excluding larger particulate matter and protecting the bearing's internal components in challenging environments. For applications requiring complete isolation, we offer configurations with double shields (626ZZ) or low-friction rubber seals (626-2RS).
Performance Characteristics
This bearing is designed for durability and high-speed performance. Its optimised internal geometry ensures minimal friction and heat generation. We produce the 626Z to standard industrial tolerances, with the capability to supply high-precision P5 grade units for applications where exceptional rotational accuracy, rigidity, and smoothness are paramount.
Applications
The versatile 626Z is ideally suited for a broad spectrum of precision and industrial equipment, including:
- High-Speed Spindles: Dental and surgical handpieces, precision drills, and small grinding spindles.
- Electric Motors: High-performance micro-motors, servo motors, and high-frequency spindles.
- Precision Machinery: Robotics arms, CNC tool changers, optical scanners, and measuring instruments.
- Automotive Components: Advanced fuel pumps, idle control valves, and auxiliary high-speed drives.
