Product Overview: The NJ 212 Cylindrical Roller Bearing
The NJ 212 bearing is a high-performance component within our extensive NJ Series of Cylindrical Roller Bearings. Engineered for exceptional radial load capacity and high-speed operation, this bearing features a single-flanged outer ring, allowing for axial displacement in one direction. With precise dimensions of a 60mm bore, 110mm outer diameter, and 22mm thickness, the NJ 212 is designed to meet the rigorous demands of heavy industrial machinery.
As a trusted supplier of industrial bearings and mechanical parts, we ensure that our NJ 212 bearings are manufactured to stringent industry standards. Their robust design, comprising rollers that are slightly crowned to relieve stress concentrations, ensures even load distribution and extended service life. These bearings are indispensable in applications where high radial loads, moderate axial loads (in one direction), and excellent rigidity are paramount. Explore our complete range of cylindrical roller bearings to find the optimal solution for your industrial needs.
Key Features of the NJ 212 Bearing
- High Radial Load Capacity: Designed with a large contact area between rollers and raceways, enabling it to withstand substantial radial forces.
- Axial Displacement Capability: The single-flanged outer ring allows the shaft to move axially relative to the housing in one direction, accommodating thermal expansion or contraction.
- High Speed Performance: Precision-engineered components and optimized internal geometry support reliable operation at high rotational speeds.
- Separable Design: The inner and outer rings, along with the roller and cage assembly, can be mounted separately, simplifying installation and maintenance.
- Low Friction: Optimized roller-raceway contact and robust cage design contribute to reduced friction and heat generation during operation.
- Durable Construction: Made from high-quality bearing steel, ensuring excellent wear resistance and long-term reliability in demanding environments.
