Product Overview: The NA 6906 Machined Needle Roller Bearing
The NA 6906 is a high-capacity needle roller bearing featuring a machined outer ring and an inner ring, with principal dimensions of 30x47x25mm. As a key component in our Needle Roller Bearings collection, this bearing is engineered for applications demanding high radial load-carrying capabilities within a compact design. Part of the versatile NA Series, it is specifically designed with an inner ring, making it suitable for arrangements where the shaft cannot be hardened and ground. The precision cage guides the needle rollers, ensuring smooth operation, reduced friction, and suitability for higher speeds.
As a premier supplier of industrial parts, we provide NA 6906 bearings that meet stringent quality standards. Their robust construction and low cross-sectional height make them an excellent choice for space-constrained yet demanding industrial and automotive applications.
