6012-2RSJEM Bearing Product Overview & Core Advantages
The 6012-2RSJEM is a sealed single row deep groove ball bearing designed for reliable performance in demanding industrial applications. This metric bearing excels at handling radial loads while also accommodating moderate axial loads in both directions. Its compact design, combined with integrated sealing and a high-grade chrome steel construction, ensures long service life and consistent operation. The bearing is pre-lubricated and features a standard radial internal clearance (CN) and ABEC 1 (ISO P0) tolerance class, making it a robust and cost-effective solution for a wide range of machinery.
6012-2RSJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 60 | Series designation, indicating a medium duty deep groove ball bearing. |
| 12 | Bore diameter code, corresponding to a 60 mm bore. |
| 2RS | Contact Rubber Seals on both sides. This provides superior protection against contaminant ingress compared to non-contact shields. |
| J | Designates a pressed steel cage, offering a good balance of strength, speed capability, and cost-effectiveness. |
| EM | Indicates the bearing is filled with a specific high-performance, lithium-based grease. The "EM" suffix denotes a optimized grease quantity and type for quiet operation and extended relubrication intervals. |
6012-2RSJEM Bearing Structural Features & Performance Benefits
- Robust Sealing for Enhanced Reliability: The 2RS (double rubber contact seals) effectively shield the internal components from dust, moisture, and other contaminants. This significantly extends bearing life in harsh environments and reduces maintenance needs.
- Optimized Cage for Stable Operation: The pressed steel cage (J) ensures proper ball guidance and separation, contributing to smooth running and stable performance at the bearing's limiting speed.
- High Load Capacity: Manufactured from high-carbon chrome steel for both rings and balls, the bearing offers a high dynamic load rating of 6609 lbf and a static load rating of 5216 lbf, providing a substantial safety margin.
- Ready-to-Install & Maintenance-Friendly: The bearing is pre-lubricated with EM grease, making it ready for immediate installation. The effective sealing often allows for maintenance-free operation throughout its service life in many applications.
- Wide Temperature Suitability: With an operating temperature range of -30°C to 120°C, this bearing is suitable for use in a variety of climatic and operational conditions.
