Product Overview: The NA 6911 Needle Roller Bearing
The NA 6911 is a high-performance needle roller bearing, meticulously engineered for applications requiring high radial load capacity within a compact design. With principal dimensions of 55x80x34mm (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 with flanges to guide the needle rollers, combined with a precision-ground inner ring, making it suitable for direct mounting on shafts that are not hardened. This design ensures optimal performance and reliability in demanding industrial and automotive environments.
As a leading supplier of Needle Roller Bearings, we guarantee that the NA 6911 meets stringent industry standards. Its unique construction provides a rigid bearing arrangement capable of accommodating high speeds and heavy loads, making it an excellent choice for space-constrained applications where other bearing types may not fit.
