Product Overview: The NJ 312 Cylindrical Roller Bearing
The NJ 312 is a single-row cylindrical roller bearing designed for high performance in demanding industrial environments. With principal dimensions of 60x130x31mm (Bore x Outer Diameter x Thickness), this bearing is a key component in our NJ 300 Series. As part of the broader Cylindrical Roller Bearings category, the NJ 312 is engineered to handle heavy radial loads and high speeds. Its specific design features two integral flanges on the inner ring and a single flange on the outer ring, allowing it to provide axial location for a shaft in one direction.
As a specialist supplier of industrial mechanical parts, we ensure our NJ 312 bearings are manufactured to precise industry standards. The separable design, where the outer ring can be mounted independently from the inner ring and roller assembly, simplifies installation and maintenance procedures, making it a practical choice for various machinery. For applications requiring different load or axial location capabilities, explore our full range of cylindrical roller bearings.
Key Features of the NJ 312 Bearing
- Single-Direction Axial Location: The flange arrangement allows the bearing to locate the shaft axially in one direction, preventing movement.
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways enables the bearing to support heavy radial forces.
- High-Speed Capability: Engineered for low friction, this bearing is suitable for applications involving high rotational speeds.
- Separable Design: The inner and outer rings can be mounted separately, simplifying the assembly and dismounting process.
- Durable Construction: Manufactured from high-quality, clean bearing steel for extended service life and enhanced wear resistance.
- Interchangeable Components: The separable components are often interchangeable with those of other manufacturers, offering installation flexibility.
