Product Overview: The NJ 213 Cylindrical Roller Bearing
The NJ 213 Cylindrical Roller Bearing is a high-performance component designed for applications requiring robust radial load capacity and high rotational speed. With precise dimensions of 65mm bore, 120mm outer diameter, and 23mm thickness, this bearing belongs to our specialized NJ 200 Series Cylindrical Roller Bearings. The 'NJ' designation signifies that this bearing features a single flange on its inner ring and no flanges on the outer ring. This design is crucial for accommodating axial displacement in one direction, effectively managing thermal expansion and contraction of the shaft relative to the housing, thereby preventing undesirable axial stresses.
As a critical part of industrial machinery, the NJ 213 bearing provides reliable and efficient operation, ensuring smooth power transmission and extended service life in demanding environments. Our comprehensive range of cylindrical roller bearings is engineered to meet stringent industry standards, offering exceptional durability and consistent performance across various sectors.
Features of the NJ 213 Bearing
- High Radial Load Capacity: Engineered with cylindrical rollers in linear contact with the raceways, enabling it to withstand heavy radial loads with superior efficiency.
- Accommodates Axial Displacement: The unique design with a single-flanged inner ring and unflanged outer ring allows for relative axial movement, preventing stress from thermal expansion.
