Product Overview: The NJ 209 Cylindrical Roller Bearing
The NJ 209 bearing is a robust and high-performing component within our extensive NJ 200 Series of Cylindrical Roller Bearings. Featuring a bore diameter of 45mm, an outer diameter of 85mm, and a thickness of 23mm, this bearing is engineered for demanding industrial applications requiring high radial load capacity and rigidity. Its design, characterized by cylindrical rollers and raceways, provides a modified line contact that significantly reduces stress concentrations, enabling it to withstand substantial loads.
Unlike many other roller bearings, the NJ 209 bearing includes a single rib on the inner ring and two ribs on the outer ring, allowing for axial displacement in one direction only. This unique configuration makes it an ideal choice for applications where the shaft needs to move axially relative to the housing due to thermal expansion or other factors. As a trusted supplier of industrial bearings, we ensure our NJ 209 bearings meet stringent industry standards, offering reliable performance and exceptional longevity in even the most challenging operating environments. Explore our full range of cylindrical roller bearings to find the perfect solution for your specific industrial needs.
Features of the NJ 209 Bearing
- High Radial Load Capacity: Designed with cylindrical rollers and a larger contact area to effectively distribute and support heavy radial loads.
- Rigid Structure: Provides excellent rigidity, crucial for precision applications where minimal deflection is required.
- Axial Displacement Capability (Single Direction): Accommodates axial movement in one direction due to its specific rib arrangement (one rib on inner, two on outer).
- Low Friction Operation: Precision-engineered components ensure smooth rotation and minimal heat generation.
- Separable Components: The inner and outer rings, along with the roller and cage assembly, can be mounted separately, simplifying installation and maintenance.
- Durable Construction: Manufactured from high-quality bearing steel for superior wear resistance and extended service life.
