Product Overview: The NA 4905 Machined Needle Roller Bearing
The NA 4905 is a high-precision machined needle roller bearing designed for applications requiring high radial load capacity within a compact design. With dimensions of 25x42x17mm (Bore x Outer Diameter x Thickness), this bearing is a key component in our NA Series of Machined Ring Bearings. It features a robust machined outer ring and comes complete with an inner ring, making it suitable for use on shafts that have not been hardened and ground. The design incorporates a cage to guide the needle rollers, ensuring smooth operation, reduced friction, and suitability for higher speeds.
As a leading supplier of industrial components, we provide the NA 4905 bearing manufactured to exacting industry standards. This ensures reliable performance and a long service life, even in demanding operational environments. It is an ideal solution for engineers and maintenance professionals looking for a space-saving bearing that does not compromise on load-carrying capability.
