SR1-5zz Bearing Product Overview & Core Advantages
The SR1-5zz is a precision miniature ball bearing designed for demanding applications requiring compact size and reliable performance. As a single row radial ball bearing with stainless steel construction and shielded design, it offers excellent corrosion resistance and protection from contaminant ingress. Its primary advantages include a high limiting speed of 54,000 rpm and the ability to handle significant radial dynamic loads up to 95 lbf, making it ideal for high-speed, compact mechanisms.
SR1-5zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SR1-5 | Bearing series and size designation | Indicates a specific miniature bearing series with a 0.09375" bore diameter. |
| zz | Double-sided metal shields (non-contact) | Provides effective protection against dust and debris while maintaining high-speed capability. Lubrication is required as this is not a sealed unit. |
SR1-5zz Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: Rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and enabling operation in a wide temperature range from -86 to 230 °F.
- Optimized Radial Load Capacity: The single row design with 6 precision balls ensures high radial dynamic load rating (95 lbf) for its compact size, supporting stable operation under load.
- High-Speed Performance: The combination of a stainless steel cage, shielded design, and MC3 radial internal clearance (0.00008" to 0.0005") contributes to a high limiting speed of 54,000 rpm.
- Precision Engineering: Manufactured to ABEC1 tolerance class with tight diameter tolerances, ensuring smooth and consistent performance in precision assemblies.
SR1-5zz Bearing Typical Application Areas
This miniature bearing is engineered for compact, high-speed devices across various industries:
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors and Drives: Stepper motors, coreless motors, and miniature DC motors.
- Office Automation: Printers, scanners, and copiers.
- Robotics and Automation: Small robotic joints, actuators, and guidance systems.
