6706zz Bearing Product Overview & Core Advantages
The 6706zz is a single row deep groove ball bearing designed for reliable performance in compact spaces. As a shielded metric bearing with ABEC-1 precision, it delivers stable operation under radial loads while offering excellent rotational characteristics. Its optimized design provides a balanced combination of high-speed capability (up to 7,000 rpm) and consistent performance across a wide temperature range (-30°C to 110°C). The bearing's compact dimensions (30mm bore × 37mm OD × 4mm width) and lightweight construction (8.3g) make it ideal for applications where space constraints and weight considerations are critical.

6706zz Bearing Structural Features & Performance Benefits
Deep Groove Raceway Design: The optimized raceway geometry ensures smooth ball movement and efficient load distribution, contributing to the bearing's radial dynamic load rating of 256 lbf and static load capacity of 213 lbf.
Shielded Protection System: Dual metal shields (zz) provide effective barrier against contaminants while retaining lubrication, extending service life in demanding environments. The C0 radial clearance (0.006mm to 0.020mm) ensures proper internal fit for general operating conditions.
Premium Material Construction: Manufactured from chrome steel rings and balls with stainless steel cage, the bearing offers excellent durability and corrosion resistance. The combination provides reliable performance up to the limiting speed of 7,000 rpm.
Precision Engineering: With ABEC-1 tolerance class and tight dimensional controls (bore tolerance: -0.01mm to 0), the bearing delivers consistent performance and smooth operation essential for precision applications.
6706zz Bearing Typical Application Areas
- Small Electric Motors: Ideal for miniature DC motors, stepper motors, and servo motors requiring compact bearing dimensions
- Office Equipment: Precision mechanisms in printers, scanners, and copiers where reliable radial load support is essential
- Medical Devices: Small-scale instrumentation and laboratory equipment benefiting from the bearing's compact profile and consistent performance
- Robotics & Automation: Joint mechanisms and small drive systems requiring high-speed capability in limited spaces
- Consumer Electronics: Cooling fans, small drives, and precision mechanisms in compact electronic devices
