FR1-5zz Bearing Product Overview & Core Advantages
The FR1-5zz is a precision miniature ball bearing designed for demanding applications requiring compact size and reliable performance. As a single row deep groove ball bearing, it is engineered to handle primarily radial loads efficiently. Its key advantages include a compact, lightweight design, high limiting speed, and consistent operation across a wide temperature range. The inclusion of shielded seals on both sides protects the bearing's interior from contamination, enhancing its service life and reliability in various operational environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| FR1-5 | Specifies the bearing size with a bore diameter of 0.09375" and an outside diameter of 0.3125". |
| zz | Indicates the bearing is equipped with shielded seals on both sides (non-contact type), offering effective protection against dust and other contaminants while minimizing friction. |
FR1-5zz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage and optimized internal geometry enables a high limiting speed of 60,000 rpm, making it suitable for high-speed applications.
- Robust Construction: Manufactured from chrome steel rings and balls, the bearing provides excellent durability and wear resistance. The stainless steel shields offer superior corrosion resistance.
- Precision Performance: Built to ABEC1 tolerance class with a specified radial internal clearance (MC3), ensuring smooth and consistent operation, which is critical for precision mechanisms.
- Compact and Lightweight: With a small bore diameter of 0.09375" and a weight of only 1.25 g, it is ideal for applications where space and weight are critical constraints.
FR1-5zz Bearing Typical Application Areas
- Small Precision Motors and Spindles
- Medical and Dental Handpieces
- Optical Encoders and Scanners
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Devices
- Robotics and Small Actuators
