SRW0 Bearing Product Overview & Core Advantages
The SRW0 is a single row deep groove ball bearing designed for high-precision radial applications. Manufactured entirely from stainless steel, this miniature bearing offers excellent corrosion resistance and reliable performance in demanding environments. Its compact design with a 0.046875" bore and lightweight 0.15 g construction makes it ideal for applications where space and weight are critical constraints. The bearing is supplied as an open type, requiring lubrication, and adheres to ABEC1 precision tolerances for consistent operation.
SRW0 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| SRW | Indicates a single row, deep groove ball bearing construction. |
| 0 | Specifies the specific size series within the miniature bearing range. |
| Open | No seals or shields, allowing for higher speeds but requiring external lubrication. |
SRW0 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made 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 deep groove raceway and 7-ball complement are engineered to efficiently support radial dynamic loads up to 19 lbf and static loads up to 5 lbf.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 99,000 rpm, making it suitable for high-speed applications.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group), ensuring smooth and quiet running with minimal vibration.
SRW0 Bearing Typical Application Areas
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors: Stepper motors, miniature DC motors, and fan motors.
- Office Automation: Printers, scanners, and copiers.
- Robotics: Small joints, gearboxes, and drone propulsion systems.
- Electronic Equipment: Computer disk drives and cooling fans.
