61910-2RS1 Bearing Product Overview & Core Advantages
The 61910-2RS1 is a metric single row deep groove ball bearing designed for exceptional performance in compact spaces. Engineered with sealed construction and manufactured to P6 tolerance class, this bearing delivers high precision and reliable operation. Its primary advantage lies in its ability to handle significant radial loads while offering protection against contamination. The combination of a stainless steel cage, high-grade chrome steel components, and factory-applied grease lubrication ensures long service life and consistent performance, making it an ideal choice for applications demanding high reliability and low maintenance.
61910-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 61910 | Basic bearing series: 619 series (extra light, ultra-thin section), 10 size code (50mm bore) |
| 2RS1 | Contact seals on both sides (2RS) with Nitrile Rubber (NBR) material, providing superior protection against dust and moisture ingress. |
61910-2RS1 Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: Manufactured to P6 tolerance class with tight dimensional control (bore: -0.01mm to 0), ensuring precise shaft positioning and smooth operation under load.
- Optimized Radial Load Capacity: The deep groove raceway and robust construction provide a high dynamic load rating of 3282 lbf and static load rating of 2653 lbf, suitable for sustained radial forces.
- Enhanced Durability & Speed: The stainless steel cage contributes to a limiting speed of 5,600 rpm, offering stable performance at high rotational speeds.
- Maintenance-Free Operation: The 2RS1 contact seals and factory-preloaded grease lubrication create a sealed, lubricated-for-life system, minimizing maintenance needs and extending service intervals.
- Wide Temperature Compatibility: Operates effectively within a temperature range of -30°C to 120°C, accommodating various industrial environments.
