Product Overview: The NK 2516 Needle Roller Bearing
The NK 2516 is a high-capacity machined ring needle roller bearing designed for applications where space is limited but high radial load capacity is essential. With principal dimensions of 25x37x16mm (Bore Diameter x Outer Diameter x Thickness), this bearing offers a compact and efficient solution. As part of our NK Series, it is a type of Machined Ring Bearing that operates without an inner ring. This design feature allows it to use a hardened and ground shaft as the inner raceway, leading to a smaller overall assembly and potential cost savings. Its robust construction makes it a reliable component in demanding industrial environments.
Our NK 2516 bearings are engineered to provide superior performance, featuring a cage that guides the needle rollers for reduced friction, lower heat generation, and the ability to operate at higher speeds. Explore our comprehensive range of Needle Roller Bearings to find the ideal solution for your specific mechanical application.
Key Features of the NK 2516 Bearing
- Compact Cross-Section: Low-profile design is ideal for applications with minimal radial space.
- High Radial Load Capacity: Needle rollers provide a large contact area to support heavy radial loads.
