Product Overview: The NUP 2308 Cylindrical Roller Bearing
The NUP 2308 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. With dimensions of 40x90x33mm, this bearing is part of our robust NUP 2300 Series. Its unique NUP design features two integral flanges on the outer ring and a single integral flange plus a loose flange ring on the inner ring. This configuration allows the bearing to act as a locating bearing, capable of accommodating axial loads and positioning the shaft in both directions. It is an essential component in machinery requiring precise shaft guidance under heavy radial loads.
As a key product in our Cylindrical Roller Bearings range, the NUP 2308 is manufactured to exacting standards to ensure superior performance and durability. The line contact between the rollers and raceways minimizes stress concentrations, making it ideal for applications involving high speeds and significant radial forces. Its separable design simplifies both mounting and dismounting procedures, reducing maintenance time and effort.
Key Features of the NUP 2308 Bearing
- Bi-Directional Axial Location: Designed to fix the shaft's position axially in both directions, providing excellent stability.
- High Radial Load Capacity: The cylindrical rollers and raceway geometry are optimized to support heavy radial loads.
- Separable Design: The inner ring with its loose flange can be mounted separately from the outer ring and roller assembly, facilitating easy installation and inspection.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Durable Construction: Manufactured from high-quality, clean bearing steel for extended service life and reliability.
- Reduced Edge Stresses: The roller profile is designed to prevent stress peaks at the roller ends, increasing bearing longevity.
