Bearing NU 2305 URB
The NU 2305 URB is a high-quality cylindrical roller bearing designed for heavy-duty industrial applications. Known for its robust construction and reliable performance, this bearing is ideal for use in machinery where high radial loads and moderate speeds are common. It ensures smooth operation, reducing friction and wear, which contributes to longer service life and improved efficiency of mechanical systems.
This bearing features a NU-type design, which means it has two integral flanges on the outer ring and no flanges on the inner ring. This configuration allows the inner ring to move axially relative to the outer ring, accommodating thermal expansion and shaft deflections without compromising performance. The URB designation indicates that this bearing is equipped with a cage designed for optimal roller guidance and reduced friction.
Key benefits of the NU 2305 URB include:
- High radial load capacity suitable for heavy machinery
- Axial displacement capability to accommodate shaft expansions
- Durable and wear-resistant materials for prolonged service life
- Efficient roller cage design for smooth rotation and reduced heat generation
The standard dimensions of the NU 2305 bearing series are commonly recognized in the industry as 25 mm inner diameter, 62 mm outer diameter, and 17 mm width. These dimensions ensure compatibility with a wide range of equipment and ease of replacement.
Whether you require a reliable bearing for industrial motors, gearboxes, or heavy machinery components, the NU 2305 URB offers a dependable solution that meets rigorous mechanical demands. Investing in this bearing helps maintain operational stability and minimizes downtime due to bearing failure.
