6012-2RS1/C3 GJN Bearing Product Overview & Core Advantages
The 6012-2RS1/C3 GJN is a single row deep groove ball bearing engineered for high reliability and robust performance in demanding applications. Its key advantage lies in its ability to efficiently handle radial loads while its sealed construction ensures long-term operational integrity. The bearing features a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a dependable balance of precision and cost-effectiveness for a wide range of industrial machinery.
6012-2RS1/C3 GJN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6012 | Basic bearing designation: 60mm bore, 95mm OD, 18mm width. |
| 2RS1 | Contact seals on both sides, providing superior protection against contaminant ingress and retaining lubricant. |
| C3 | Radial internal clearance greater than Normal (C0). Ideal for applications with shaft expansion or heavy interference fits. |
| GJN | Indicates the use of a high-quality, heat-stabilized polyamide 66 cage, offering low weight and excellent performance at high speeds. |
6012-2RS1/C3 GJN Bearing Structural Features & Performance Benefits
Optimized Sealing: The 2RS1 contact seals are a critical feature, providing a high degree of protection against dust, moisture, and other contaminants. This significantly extends the bearing's service life and reduces maintenance requirements, making it a low-maintenance solution for harsh environments.
Robust Load Capacity: With a dynamic load rating of 6609 lbf and a static load rating of 5216 lbf, this bearing is designed to handle significant radial loads reliably. The deep groove raceway and high-quality chrome steel construction contribute to its durability.
High-Speed Capability: The lightweight and robust GJN polyamide cage ensures stable operation and low friction, enabling a high limiting speed of 7,100 rpm. This makes the bearing suitable for a variety of high-speed applications.
Thermal Stability: The specified C3 clearance accommodates differential thermal expansion between the shaft and housing, preventing preload and potential seizure in applications with operating temperatures ranging from -30°C to 120°C.
6012-2RS1/C3 GJN Bearing Typical Application Areas
The 6012-2RS1/C3 GJN is a versatile component found in numerous industrial sectors. Its combination of sealed construction, high-speed performance, and robust load capacity makes it ideal for:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Equipment (e.g., conveyor pulleys)
