SF602x Bearing Product Overview & Core Advantages
The SF602x is a metric miniature ball bearing designed for precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, this single row, open-type bearing is engineered for radial loads and offers excellent corrosion resistance. Its small footprint, with a bore diameter of 2.5 mm and outside diameter of 8 mm, makes it ideal for space-constrained assemblies. The bearing features a standard ABEC1 tolerance class and MC3 radial internal clearance, providing a balance of precision and operational reliability for a wide range of industrial and electronic applications.
SF602x Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF602x | Base model number indicating a specific series of miniature radial ball bearings. |
| Open | No seals or shields, allowing for higher speeds and easy re-lubrication. |
| ABEC1 | Specifies the precision tolerance class, ensuring dimensional accuracy and runout control. |
| MC3 | Denotes the radial internal clearance group (0.002mm to 0.013mm), suitable for applications with moderate temperature variations. |
SF602x Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and durability in harsh environments, and ensuring compliance with ROHS and REACH standards.
- Optimized Load Capacity: With a dynamic load rating of 95 lbf and a static load rating of 29 lbf, this bearing is designed to handle significant radial loads for its compact size.
- High-Speed Capability: The open design and precision-ground components contribute to a high limiting speed of 54,000 rpm, making it suitable for high-speed spindles and miniature motors.
- Precision Engineering: The ABEC1 tolerance class ensures consistent performance and low vibration, which is critical for sensitive instrumentation and precision mechanisms.
