Product Overview: The N 219 Cylindrical Roller Bearing
The N 219 is a single-row cylindrical roller bearing engineered to handle high radial loads at high speeds. With principal dimensions of 95x170x32mm, this bearing is a key component in our N 200 Series within the broader Cylindrical Roller Bearings category. The 'N' design features two integral flanges on the inner ring and a flangeless outer ring. This configuration makes it an ideal non-locating bearing, allowing it to accommodate axial displacement of the shaft relative to the housing in both directions, which is essential for managing thermal expansion or minor mounting inaccuracies.
As a specialist supplier of industrial components, we ensure our N 219 bearings meet stringent quality standards. Its separable design—where the outer ring can be mounted independently of the inner ring and roller assembly—greatly simplifies installation and maintenance procedures in complex machinery.
Key Features of the N 219 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the support of heavy radial loads.
- Axial Displacement: Designed as a non-locating bearing, it permits free axial movement between the shaft and housing in both directions.
- Separable Design: The inner ring with the roller and cage assembly can be mounted separately from the outer ring, facilitating easier installation and inspection.
- High-Speed Performance: Engineered for low friction and optimized internal geometry, making it suitable for high-rotational speed applications.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long operational lifespan.
- Interchangeability: Produced to standardized dimensions, ensuring it is interchangeable with other manufacturers' N 219 bearings.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy radial forces common in gear systems.
- Electric Motors: Often used on the non-locating (floating) end of motor shafts to accommodate thermal expansion.
- Pumps and Compressors: Ensures reliable rotation of shafts in demanding fluid and gas handling equipment.
- Construction Machinery: Used in heavy equipment like excavators and cranes where durability is critical.
- Rolling Mills: Capable of withstanding the extreme radial loads found in steel and metal processing applications.
- Vibrating Screens: Its robust design makes it suitable for machinery subjected to heavy vibrations and shock loads.
- Automotive Transmissions: Provides durable and efficient support for transmission system components.
