Product Overview: The NU 2309 Cylindrical Roller Bearing
The NU 2309 is a high-capacity, single-row cylindrical roller bearing with dimensions of 45x100x36mm. As a key component in our Cylindrical Roller Bearings range, this bearing belongs to the robust NU 2300 Series. It features a separable design where the inner ring has two integral flanges and the outer ring is flangeless. This configuration is engineered to accommodate heavy radial loads and high speeds, while also allowing for axial displacement of the shaft relative to the housing in both directions. This makes the NU 2309 an excellent choice for non-locating bearing positions, especially in applications subject to thermal expansion.
Manufactured to exacting industry standards, the NU 2309 ensures reliable performance and a long service life. Its design minimizes friction and heat generation, making it suitable for demanding industrial environments where precision and durability are paramount.
Key Features of the NU 2309 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads and high stiffness.
- Axial Displacement: The NU design allows the shaft to move axially in either direction relative to the housing, compensating for thermal expansion or mounting inaccuracies.
- Separable Design: The inner ring can be removed from the outer ring and roller assembly, simplifying the mounting and dismounting process.
- High-Speed Capability: Engineered for low friction, this bearing is well-suited for applications requiring high rotational speeds.
- Durable Construction: Made from high-quality, through-hardened bearing steel for superior wear resistance and longevity.
- Dimensional Stability: Precision manufacturing ensures consistent dimensions for interchangeability and reliable performance.
Common Applications
