SRW1-5zz Bearing Product Overview & Core Advantages
The SRW1-5zz is a single row deep groove ball bearing designed for precision applications requiring reliable radial load capacity. Manufactured entirely from stainless steel components, it offers excellent corrosion resistance. This shielded bearing features an extended inner ring for simplified axial location and is pre-lubricated for immediate installation. Its compact design and ABEC1 tolerance class make it suitable for applications demanding consistent performance and moderate precision.
SRW1-5zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| zz | Indicates shielded construction on both sides. These non-contact shields protect against contaminant ingress while minimizing friction, contributing to the bearing's limiting speed of 54,000 rpm. |
| W | Denotes an extended inner ring design, providing a wider shoulder for secure axial positioning and simplified assembly. |
SRW1-5zz Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and six precision balls provide stable radial load handling with a dynamic rating of 95 lbf.
- Corrosion Resistance: All critical components, including rings, balls, cage, and shields, are manufactured from stainless steel, ensuring long-term performance in harsh environments.
- High-Speed Capability: The combination of a stainless steel cage, shielded design, and optimized internal geometry enables a high limiting speed of 54,000 rpm.
- Pre-Lubricated & Ready-to-Use: Factory-applied lubrication allows for immediate operation across a wide temperature range from -86 to 230 °F.
- Precision Internal Clearance: The MC3 radial internal clearance (0.00008" to 0.0005") ensures smooth, low-noise operation suitable for precision instruments.
