Product Overview: The N 309 Cylindrical Roller Bearing
The N 309 Cylindrical Roller Bearing is a high-capacity, single-row bearing designed for applications demanding robust radial support and accommodation of axial displacement. With principal dimensions of 45mm Bore Diameter, 100mm Outer Diameter, and 25mm Thickness, this bearing is a key component in our N 300 Series within the broader Cylindrical Roller Bearings collection. The 'N' designation signifies a design where the inner ring has two integral flanges, and the outer ring is flangeless. This configuration allows the shaft to move axially in relation to the housing in both directions, making it ideal for use as a non-locating bearing.
Manufactured to precision standards, the N 309 is engineered to handle heavy radial loads at high speeds. Its separable design, where the inner ring with the roller and cage assembly can be mounted independently of the outer ring, simplifies both installation and maintenance procedures. This feature is particularly advantageous in machinery where components need to be assembled separately or where access is limited.
Key Features of the N 309 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the support of heavy radial loads.
- Axial Displacement Accommodation: The flangeless outer ring design allows the bearing to accommodate thermal expansion or contraction of the shaft.
- Separable Design: The inner and outer rings can be mounted separately, which greatly simplifies the mounting and dismounting process.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Made from high-grade bearing steel for superior durability, wear resistance, and a long operational lifespan.
- Interchangeability: Manufactured to standard dimensions, ensuring it can be easily interchanged with other equivalent bearings.
Common Applications for N 309 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors: Used as a non-locating bearing in large electric motors to manage shaft expansion.
- Pumps and Compressors: Ensures smooth and efficient operation of rotating assemblies under heavy loads.
- Construction Machinery: Found in heavy equipment like excavators and cranes where durability is critical.
