SRW2-6 Bearing Product Overview & Core Advantages
The SRW2-6 is a precision miniature ball bearing designed for demanding applications requiring high reliability in compact spaces. As a single row deep groove ball bearing with an extended inner ring, it excels at handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its compact dimensions (0.125" bore x 0.375" OD) and ABEC1 precision class make it an ideal component for high-speed, low-torque mechanisms where consistent performance is critical.
SRW2-6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW2-6 | Standard series designation for a miniature, stainless steel, deep groove ball bearing. |
| No Seal Suffix | The bearing is open, allowing for optimal speed capability but requiring a lubricated and clean operating environment. |
| Extended Inner Ring | Facilitates easier mounting and axial location, increasing design flexibility. |
SRW2-6 Bearing Structural Features & Performance Benefits
- High-Speed Capability: The open design and stainless steel cage minimize friction and drag, enabling a high limiting speed of 47,700 rpm.
- Corrosion Resistance: Constructed entirely from stainless steel (rings, balls, cage), making it suitable for applications exposed to moisture, chemicals, or requiring washdown.
- Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3), ensuring smooth and quiet operation with minimal runout.
- Robust Load Capacity: Engineered to handle a dynamic radial load of 110 lbf and a static radial load of 37 lbf despite its miniature size.
- Wide Temperature Range: Operates effectively from -86 to 230 °F, accommodating various environmental conditions.
SRW2-6 Bearing Typical Application Areas
This bearing is commonly specified in:
- Precision Instruments: Optical encoders, medical devices, and laboratory equipment.
- Small Motors and Gearboxes: Stepper motors, servo motors, and miniature DC motors.
- Office Automation Equipment: Printers, scanners, and copiers.
- Robotics and Automation: Small robotic joints, actuators, and guidance systems.
- Consumer Electronics: High-speed cooling fans and small drive mechanisms.
