6312-2RSJEM Bearing Product Overview & Core Advantages
The 6312-2RS JEM is a single row deep groove ball bearing featuring integral contact seals (2RS) and pre-lubrication. Engineered for high reliability in demanding applications, this metric bearing is designed to primarily accommodate radial loads while also handling moderate axial loads in both directions. Its sealed construction provides excellent protection against contamination, making it a robust, maintenance-free solution ideal for a wide range of industrial machinery.
6312-2RSJEM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6312 | Basic bearing designation: 60mm bore, 130mm OD, 31mm width. | Defines the standard bearing dimensions for fit and interchangeability. |
| 2RS | Bearing is equipped with two synthetic rubber contact seals, one on each side. | Provides superior protection from dust, dirt, and moisture, retaining lubricant for a long service life. |
| JEM | Manufacturer-specific suffix indicating the use of a high-quality, pre-applied grease. | Ensures optimal lubrication from the start, contributing to quiet operation and immediate readiness for use. |
6312-2RSJEM Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing delivers high strength and durability. With a radial dynamic load rating of 18,412 lbf and a static load rating of 11,735 lbf, it is built to withstand significant radial forces in continuous operation.
- Sealed & Pre-Lubricated for Maintenance-Free Operation: The double rubber seals (2RS) effectively shield the internal components from contaminants. Combined with the factory-applied grease, this design eliminates the need for re-lubrication, reducing maintenance costs and downtime.
- Precision & Reliability: Manufactured to ABEC 1 | ISO P0 tolerance class with a standard radial internal clearance (CN), this bearing ensures consistent performance, smooth running, and reliable operation in a vast array of general industrial applications.
6312-2RSJEM Bearing Typical Application Areas
The 6312-2RS JEM is a versatile component suited for numerous applications requiring reliable, sealed bearing performance, including:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Material Handling Equipment (conveyors, pulleys)
- Agricultural Machinery
- General Industrial Machinery with moderate speed requirements
