SR2-5 Bearing Product Overview & Core Advantages
The SR2-5 is a single row deep groove ball bearing designed for precision applications requiring reliable performance in compact spaces. Manufactured entirely from stainless steel, it offers excellent corrosion resistance and is suitable for a wide operating temperature range. This bearing is engineered to primarily support radial loads and is characterized by its open design, which allows for versatile lubrication options to meet specific operational needs. Its ABEC1 precision class ensures consistent performance for general industrial applications demanding high reliability.
SR2-5 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR2-5 | Standard model designation for an inch-series, single row deep groove ball bearing. |
| Open (Seal Type) | No integral seals or shields. Requires external sealing and lubrication for the application environment. |
SR2-5 Bearing Structural Features & Performance Benefits
- All-Stainless-Steel Construction: The rings, balls, and cage are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments, including those with exposure to moisture and chemicals.
- Deep Groove Raceway: The geometry of the deep groove raceway enables efficient handling of radial loads and moderate axial loads in both directions.
- Precision & Clearance: Built to ABEC1 tolerance class with an MC3 radial internal clearance, this bearing offers a balance of precision and operational stability for a wide range of speeds and temperatures.
- High-Speed Capability: With a limiting speed of 54,000 rpm, it is well-suited for applications requiring high rotational velocities.
