Product Overview: The NJ 1216 Cylindrical Roller Bearing
The NJ 1216 is a high-capacity, single-row cylindrical roller bearing with dimensions of 80x140x26mm. As a key component in our Cylindrical Roller Bearings range, this bearing is engineered to handle substantial radial loads at high speeds. It belongs to the NJ 1200 Series, which is characterized by a design featuring two flanges on the outer ring and a single flange on the inner ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in one direction, making it ideal for applications with thermal expansion.
Manufactured to exacting industry standards, the NJ 1216 bearing provides exceptional rigidity and durability. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies installation, inspection, and maintenance procedures. This makes it a preferred choice for demanding industrial environments where reliability and ease of service are paramount.
Features of the NJ 1216 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the support of heavy radial forces.
- Axial Displacement Capability: Accommodates shaft expansion or contraction in one direction, preventing stress from thermal variations.
- Separable Design: The inner ring is detachable from the outer ring and roller cage assembly, facilitating easy mounting and dismounting.
- High-Speed Performance: Engineered for low friction and optimal performance in high-speed rotational applications.
- Enhanced Rigidity: Provides strong, stiff support for shafts, minimizing deflection under load.
- Durable Construction: Made from premium-grade bearing steel for excellent wear resistance and a long operational lifespan.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
