Product Overview and Core Advantages
The MF62 is a metric single row deep groove ball bearing engineered for precision applications requiring compact dimensions and reliable performance. This open-type radial bearing features a standard bore design with excellent dimensional stability, making it ideal for high-speed operations up to 75,000 rpm. Manufactured with chrome steel rings and balls combined with a stainless steel cage, it delivers optimal durability and corrosion resistance in demanding environments.
Model Code Technical Breakdown
| Code Element | Technical Significance |
|---|---|
| MF62 | Basic designation indicating bearing dimensions: 2mm bore × 6mm OD × 2.5mm width |
| Open | No seals or shields, enabling maximum speed capability and requiring external lubrication |
| MC3 | Radial internal clearance group (0.002-0.013mm) optimized for precision applications |
| ABEC1 | Tolerance class ensuring consistent dimensional accuracy and smooth operation |
Structural Features and Performance Benefits
Compact Design Excellence: With ultra-small dimensions (2×6×2.5mm) and lightweight construction (0.34g), this bearing enables space-optimized solutions in miniature mechanisms.
High-Speed Capability: The stainless steel cage and optimized ball complement (6 balls of 1.2mm diameter) ensure stable operation at limiting speeds of 75,000 rpm, making it suitable for high-rotation applications.
Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3 group), this bearing delivers consistent running accuracy and minimal vibration.
Robust Load Capacity: Despite its miniature size, it maintains substantial dynamic load rating (63 lbf) and static load rating (18 lbf) for reliable radial load support.
MF62 Bearing Typical Application Areas
- Precision instruments and measuring devices requiring miniature components
- Small DC motors and micro-motors in consumer electronics and medical devices
- Office automation equipment including printers, scanners, and copiers
- Robotic joints and miniature mechanical assemblies
- Dental handpieces and medical instrumentation requiring high-speed rotation
