RW1-5 Bearing Product Overview & Core Advantages
The RW1-5 is a precision miniature ball bearing designed for demanding applications requiring compact dimensions and reliable performance. As a single row deep groove ball bearing with an extended inner ring, it excels at handling radial loads while offering versatile mounting options. Manufactured to ABEC1 precision tolerances, this bearing is ideal for high-speed operation and applications where space is at a premium, ensuring long service life and consistent operation in a wide temperature range.
RW1-5 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| RW1-5 | Standard model designation for this specific inch-series miniature bearing. |
| Open (Seal Type) | No integral seals or shields. Allows for custom lubrication schemes but requires a clean operating environment. |
| Extended Inner Ring | The inner ring protrudes beyond the bearing width, facilitating easier mounting and axial location. |
RW1-5 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage, six precision chrome steel balls, and ABEC1 precision enables a high limiting speed of 60,000 rpm, making it suitable for demanding rotational applications.
- Radial Load Capacity: The deep groove raceway and robust construction provide a dynamic load rating of 106 lbf and a static load rating of 32 lbf, ensuring reliable performance under significant radial stresses.
- Precision & Stability: Manufactured with tight dimensional tolerances and a controlled MC3 radial internal clearance, this bearing offers smooth, low-vibration operation essential for precision instruments.
- Material Durability: Components made from chrome steel (rings and balls) and stainless steel (cage) provide excellent resistance to wear and corrosion, contributing to a long operational lifespan.
RW1-5 Bearing Typical Application Areas
This miniature bearing is engineered for compact, high-speed devices across various industries. Key applications include:
- Small Precision Motors: Ideal for spindle support in miniature DC motors and stepper motors.
- Medical and Dental Instruments: Used in handheld tools, pumps, and scanners where compact size and reliability are critical.
- Office Automation Equipment: Found in printers, scanners, and small fans.
- Instrumentation and Control Systems: Suitable for encoders, sensors, and guidance systems.
- Robotics and Automation: Used in small joints, actuators, and drive mechanisms.
