SRW4 Bearing Product Overview & Core Advantages
The SRW4 inch series ball bearing is a precision-engineered single row radial ball bearing designed for reliable performance in demanding applications. Manufactured to ABEC1 tolerance class, this bearing features an extended inner ring for enhanced mounting stability and an open design that allows for customized lubrication solutions. Constructed entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance and is suitable for a wide temperature range from -86 to 230 °F. Its compact design provides a high radial dynamic load rating of 255 lbf in a minimal footprint, making it ideal for applications requiring precision and durability.
SRW4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW4 | Series designation for inch-size, single row ball bearings with extended inner ring. |
| Open | No integral seals or shields, allowing for application-specific lubrication. |
| ABEC1 | Specifies the precision tolerance class, ensuring consistent running accuracy. |
| MC3 | Defines the radial internal clearance group (0.00008" to 0.0005"). |
SRW4 Bearing Structural Features & Performance Benefits
- Extended Inner Ring Design: Provides a larger contact surface for secure shaft mounting, improving stability and simplifying axial location.
- All-Stainless Steel Construction: The use of stainless steel for all critical components (rings, 8 precision balls, and cage) ensures superior corrosion resistance and longevity in harsh environments.
- Optimized Load Capacity: The single row ball bearing design is engineered to handle significant radial loads (255 lbf dynamic, 101 lbf static) efficiently.
- High-Speed Capability: With a limiting speed of 34,200 rpm, the bearing is suitable for high-rotation applications. The open design and stainless steel cage contribute to stable operation at high velocities.
- Precision Engineering: Manufactured to ABEC1 standards with controlled radial internal clearance, ensuring smooth, low-vibration, and low-noise operation.
SRW4 Bearing Typical Application Areas
- Medical and Dental Instruments
- Precision Optical Devices and Encoders
- Small Electric Motors and Servo Drives
- Food Processing and Packaging Machinery (where corrosion resistance is critical)
- Laboratory and Analytical Equipment
- High-speed spindles in compact machinery
