RNA6916 iso9001 Needle Roller Bearing NA6916 gcr15 steel needle bearing
NA6916 is a needle roller bearing with a separable design (the inner ring and needle roller assembly can be removed from the outer ring), featuring standard internal clearance, and is typically supplied unlubricated. Its core design relies on precision-engineered needle rollers—small-diameter, high-length rollers that enable it to withstand heavy radial loads while occupying a compact radial space. The separable structure facilitates easy installation, maintenance, and replacement, as the inner ring-roller assembly can be handled independently from the outer ring.
The needle rollers are manufactured with high surface finish and dimensional accuracy, ensuring uniform load distribution across their contact areas with the inner and outer rings. This design not only maximizes load-carrying capacity but also maintains stable, low-friction operation even under high-speed or intermittent load conditions. The standard internal clearance balances rotational flexibility and load stability, while the unlubricated supply format allows users to select optimal lubrication (grease or oil) based on specific operating temperatures, speeds, and environmental demands.
