MF137zz Bearing Product Overview & Core Advantages
The MF137zz is a miniature deep groove ball bearing designed for precision applications requiring reliable performance in compact spaces. This metric bearing features a single-row design with shielded construction, providing effective protection against contamination. Engineered with chrome steel rings and balls combined with a stainless steel cage, it delivers excellent durability and smooth operation. Its primary advantages include a compact flange design for secure mounting, a high limiting speed of 40,000 rpm, and compliance with ROHS and REACH environmental standards, making it ideal for high-speed, radial load applications where space is at a premium.

MF137zz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage and optimized internal geometry enables a maximum limiting speed of 40,000 rpm, suitable for demanding high-rotation applications.
- Robust Radial Load Capacity: With a radial dynamic load rating of 104 lbf and radial static load rating of 50 lbf, this bearing provides reliable performance under significant radial loads.
- Enhanced Contamination Protection: The double-sided stainless steel shields (zz) effectively retain lubrication and exclude larger particulate contaminants, extending service life.
- Precision Engineering: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), ensuring consistent, low-vibration operation.
- Secure Mounting: The integrated flange (outer diameter: 14.6 mm) simplifies axial location and prevents bearing creep in housings, enhancing system rigidity.
MF137zz Bearing Typical Application Areas
- Small Precision Motors: Spindle support in miniature DC motors and stepper motors.
- Office Automation Equipment: Paper feed rollers in printers, scanners, and copiers.
- Medical Devices: Small pumps, dental handpieces, and laboratory instrumentation.
- Computer Peripherals: Cooling fans, hard disk drive spindles, and optical disc drives.
- Robotics and Automation: Joints and guides in small robotic arms and linear motion systems.
