SR1-5 2rs Bearing Product Overview & Core Advantages
The SR1-5 2RS is a precision miniature ball bearing engineered for demanding applications requiring compact size and reliable performance. This single row deep groove ball bearing features integral rubber seals (2RS) for effective contamination protection. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its design is optimized to handle radial loads efficiently while accommodating moderate axial loads, making it an ideal choice for high-speed, low-torque applications where longevity and consistent operation are critical.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SR1-5 | Standard bearing series designation indicating specific bearing dimensions (0.09375" bore, 0.3125" OD) |
| 2RS | Bearing is sealed on both sides with Nitrile Rubber (Buna-N) seals for superior protection against dust and moisture |
SR1-5 2rs Bearing Structural Features & Performance Benefits
- Corrosion-Resistant Construction: All critical components—rings, balls, and cage—are manufactured from stainless steel, ensuring long-term performance in harsh environments and providing excellent bearing service life.
- Effective Sealing: The dual-contact rubber seals (2RS) effectively retain lubricant and exclude contaminants, making the bearing suitable for applications where maintenance is difficult or impossible.
- Precision Performance: Built to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.00008" to 0.0005"), ensuring smooth and quiet operation with minimal vibration.
- High-Speed Capability: The optimized design, including a stainless steel cage and six precision balls, supports a limiting speed of 54,000 rpm, ideal for high-speed applications.
- Robust Load Capacity: With a dynamic load rating of 95 lbf and a static load rating of 29 lbf, this bearing provides reliable support for significant radial forces in a compact package.
SR1-5 2rs Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment
- Small Motors & Drives: Stepper motors, DC micromotors, and fan motors
- Office Automation: Printers, scanners, and copiers
- Robotics & Automation: Small robotic joints, linear actuators, and precision positioning systems
- Consumer Electronics: Drones, small power tools, and high-performance computer cooling fans
