Product Overview: The NA 6815 Needle Roller Bearing
The NA 6815 is a high-precision machined ring needle roller bearing, engineered for applications demanding high radial load capacity within a minimal space. With principal dimensions of 75mm Bore Diameter, 95mm Outer Diameter, and 10mm Thickness, this bearing's slim profile makes it an excellent choice for compact mechanical designs. As part of our NA Series, it includes a precision-ground inner ring, allowing it to be used on shafts that have not been hardened and ground, providing greater design flexibility. The robust construction ensures reliable performance under heavy loads and high rotational speeds.
Sourced for quality and performance, the NA 6815 is a vital component in our extensive catalog of Needle Roller Bearings. Its design, featuring a cage to guide the rollers, ensures stability and reduces friction, making it suitable for a wide range of industrial and automotive applications where performance and durability are paramount.
