R2-6zz Bearing Product Overview & Core Advantages
The R2-6zz is a precision miniature ball bearing designed for applications demanding high reliability in compact spaces. As a single row deep groove ball bearing, it is primarily engineered to support radial loads efficiently. Its inch-series dimensions, including a 1/8" bore, make it ideal for precision instruments and small machinery. The bearing features shielded construction on both sides, offering superior protection against contaminant ingress while maintaining smooth operation. Manufactured to ABEC1 tolerance standards, it ensures consistent performance and is pre-lubricated for immediate use, providing an excellent balance of performance, durability, and value for high-volume OEM applications.
R2-6zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| R | Inch Series Bearing | Standardized inch dimensions for compatibility with North American machinery. |
| 2-6 | Bore & Outside Diameter Code | Specifies the compact size: 0.125" bore and 0.375" outside diameter. |
| zz | Double Shields (Both Sides) | Provides effective contamination protection, extending bearing life and reducing maintenance in dusty environments. |
R2-6zz Bearing Structural Features & Performance Benefits
- High-Grade Material Construction: The combination of chrome steel rings and balls with a stainless steel cage provides excellent wear resistance and corrosion protection, ensuring long-term operational reliability.
- Optimized Load Capacity: With a dynamic load rating of 122 lbf and a static load rating of 41 lbf, this bearing is robust enough to handle significant radial forces for its size.
- High-Speed Capability: The lightweight stainless steel cage and precision-ground components enable a limiting speed of 53,000 rpm, making it suitable for high-speed applications like small spindles and fans.
- Pre-Lubricated & Sealed Design: The double stainless steel shields retain the factory-applied lubricant, creating a low-maintenance solution that operates reliably across a wide temperature range from -86 to 230 °F.
- Precision Internal Clearance: The specified MC3 radial internal clearance (0.00008" to 0.0005") ensures smooth, low-noise, and low-vibration operation, which is critical for sensitive electronic and precision equipment.
R2-6zz Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Electric Motors: Stepper motors, DC micromotors, and cooling fans.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and Automation: Small robotic joints, conveyor belt rollers, and linear guides.
