Product Overview: N 218 Cylindrical Roller Bearing
The N 218 Cylindrical Roller Bearing is a high-performance component engineered to handle substantial radial loads at high rotational speeds. With dimensions of 90x160x30mm, this bearing is a key part of our N 200 Series within the broader Cylindrical Roller Bearings collection. The 'N' designation signifies a specific design where the inner ring is separable, featuring no flanges, while the outer ring has two integral flanges. This construction allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions in various industrial applications.
As a specialist supplier of industrial components, we ensure our N 218 bearings are manufactured to the highest industry standards, providing reliability and longevity in demanding operational environments. The line contact between the rollers and raceways provides a high degree of stiffness and exceptional load-carrying capacity, essential for heavy-duty machinery.
Key Features of the N 218 Bearing
- High Radial Load Capacity: The cylindrical rollers and their line contact with the raceways allow the bearing to support heavy radial loads.
- High-Speed Performance: Engineered with low friction characteristics, making it suitable for applications requiring high rotational speeds.
- Separable Inner Ring: The inner ring can be mounted independently of the outer ring and roller assembly, which greatly simplifies installation, inspection, and maintenance procedures.
- Accommodates Axial Displacement: The design allows for thermal expansion or contraction of the shaft by permitting axial movement within the housing in both directions.
- Robust and Durable: Constructed from premium-quality, hardened bearing steel for exceptional wear resistance and a long operational life.
- High Stiffness: Provides rigid support for shafts, minimizing deflection under heavy loads.
Common Applications for N 218 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy loads typical in transmission systems.
- Electric Motors: Used as non-locating bearings in large electric motors to support the rotor shaft while allowing for thermal expansion.
