SRW1 Bearing Product Overview & Core Advantages
The SRW1 is a single row deep groove ball bearing designed for precision applications requiring reliable radial load capacity. Manufactured entirely from stainless steel (rings, balls, and cage), it offers excellent corrosion resistance. This bearing features an extended inner ring for secure axial location and is supplied as an open type, requiring lubrication for optimal performance. Its compact inch dimensions and ABEC1 precision make it ideal for applications demanding high reliability in challenging environments.
SRW1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW1 | Base model number for this specific inch-series, single row deep groove ball bearing. |
| Open | No integral seals or shields. This allows for higher limiting speeds but requires external lubrication and protection from contaminants. |
SRW1 Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The use of stainless steel for all core components provides superior corrosion resistance, making the bearing suitable for a wide temperature range (-86 to 230 °F) and harsh environments, including those requiring washdown or exposure to certain chemicals.
- Extended Inner Ring Design: The extended inner ring facilitates easier mounting and provides a positive locating surface, enhancing axial stability in the assembly.
- Optimized Internal Geometry: With 7 precision balls, the bearing achieves a balanced radial dynamic load rating of 40 lbf and smooth operation. The specified MC3 radial internal clearance ensures reliable performance under operational temperature variations.
- High-Speed Capability: The open design, combined with a stainless steel cage, enables a high limiting speed of 81,000 rpm, suitable for demanding high-speed applications.
SRW1 Bearing Typical Application Areas
This bearing is commonly specified in:
- Precision Instruments and optical devices
- Small Motors and miniature gearboxes
- Medical and dental handpieces
- Food processing and packaging equipment (where corrosion resistance is critical)
- Robotics and small-scale automation
