Product Overview and Core Advantages
The SRW156 is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Manufactured entirely from stainless steel, this bearing offers excellent corrosion resistance. Its open design allows for versatile lubrication options, while the extended inner ring facilitates easier mounting and axial location. Engineered to ABEC1 precision class standards, it delivers consistent performance for radial load applications, making it an ideal component for compact assemblies demanding high rotational speeds and durability.
SRW156 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW | Series designation for a specific range of miniature, stainless steel ball bearings. |
| 156 | Specific size identifier within the SRW series. |
| Open (No Seal) | The bearing is supplied without seals or shields, allowing for custom lubrication and high-speed operation. |
| Extended Inner Ring | The inner ring protrudes beyond the outer ring, simplifying axial positioning and locking. |
Structural Features and Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and suitability for harsh environments and clean applications.
- Deep Groove Raceway: Optimized for handling significant radial loads and moderate axial loads in both directions.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 47,700 rpm, making it suitable for demanding high-RPM applications.
- Precision Engineering: Conforms to ABEC1 tolerance class with a controlled MC3 radial internal clearance, ensuring smooth and quiet operation with minimal vibration.
- Extended Inner Ring: This feature enhances ease of installation and provides a positive location surface, improving overall assembly accuracy and rigidity.
SRW156 Bearing Typical Application Areas
- Precision Instruments and optical devices
- Small electric motors and miniature gearboxes
- Medical and dental handpieces
- Robotics and automation joints
- Office machinery and computer disk drives
- Food processing and packaging equipment (where corrosion resistance is critical)
