SR6 Bearing Product Overview & Core Advantages
The SR6 is a high-precision, single row deep groove ball bearing designed for demanding applications requiring reliable performance. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. This bearing is engineered to primarily support radial loads and is characterized by its compact design, making it ideal for applications where space is limited and high reliability is essential. Its ABEC1 precision class ensures consistent and smooth operation.
SR6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR6 | Standard bearing series designation with a 0.375" bore. |
| Open (Seal Type) | No integral seals or shields. Requires external sealing in contaminated environments. |
| ABEC1 | Defines the dimensional and running accuracy to a standard precision grade. |
| MC3 (Radial Internal Clearance) | Specifies a greater than normal internal clearance, suitable for applications with significant thermal expansion or where a loose fit is used. |
SR6 Bearing Structural Features & Performance Benefits
- All-Stainless Steel Construction: The rings, balls, and stainless steel cage provide superior corrosion resistance, making the bearing suitable for harsh environments, including wash-down and chemical exposure.
- Optimized Load Capacity: With a radial dynamic load rating of 574 lbf and a static load rating of 230 lbf, this bearing is robust for its compact size.
- High-Speed Capability: The precision-ground components and stable cage design contribute to a high limiting speed of 28,800 rpm.
- Wide Temperature Range: Operates effectively from -86 to 230 °F, accommodating a broad spectrum of industrial and specialized applications.
- Pre-Engineering Consideration: The MC3 radial internal clearance is a critical feature for applications involving thermal gradients or specific mounting conditions, preventing preload and ensuring smooth operation.
