SR4Azz Bearing Product Overview & Core Advantages
The SR4Azz is a high-precision, single row deep groove ball bearing designed for demanding applications requiring reliable performance and long service life. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its compact design and shielded construction provide effective protection against contaminants while maintaining low friction. This bearing is engineered to handle primarily radial loads and is characterized by its ABEC1 precision class, making it a robust and dependable choice for high-speed, high-reliability machinery.
SR4Azz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR4 | Standard bearing series designation |
| A | Unspecified internal design feature |
| zz | Double-sided stainless steel shields for maximum contaminant exclusion |
SR4Azz Bearing Structural Features & Performance Benefits
- Corrosion Resistance: Constructed entirely from 300 series stainless steel (rings, balls, cage, and shields), ensuring reliable operation in harsh environments and providing excellent durability.
- Contaminant Protection: The double-sided shielded (ZZ) design effectively seals the bearing, protecting the internal components from dust and debris, which enhances operational life.
- High-Speed Capability: With a limiting speed of 32,400 rpm, it is suitable for high-velocity applications. The stainless steel cage and optimized internal geometry contribute to stable performance at high rotational speeds.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.00008" to 0.0005"), ensuring smooth and precise operation with minimal vibration and noise.
- Load Handling:
- Radial Dynamic Load Rating: 401 lbf
- Radial Static Load Rating: 145 lbf
SR4Azz Bearing Typical Application Areas
- Medical and Dental Equipment: Ideal for handheld tools, pumps, and small motors where corrosion resistance and reliability are critical.
- Food Processing Machinery: Suitable for conveyors and mixers due to stainless steel construction and compliance with hygiene standards.
- Precision Instruments and Optical Devices: Used in encoders, scanners, and gauges requiring ABEC1 precision and smooth rotation.
- Small Electric Motors and Gearboxes: Provides durable support in compact motor designs for appliances, robotics, and power tools.
- Aerospace and Defense Components: Applied in auxiliary systems and instrumentation where weight, reliability, and corrosion resistance are paramount.
