Product Overview: The NA 6909 Machined Ring Needle Roller Bearing
The NA 6909 is a high-capacity machined ring needle roller bearing with dimensions of 45x68x35mm. As a key component in our NA Series, this bearing is engineered to handle substantial radial loads within a minimal cross-sectional height, making it an excellent choice for applications where space is a constraint. It features a robust machined outer ring and a full complement of caged needle rollers, ensuring high rigidity and operational accuracy. This model includes an inner ring, allowing for its use on shafts that have not been hardened and ground, providing greater design flexibility.
As a premier supplier of industrial components, we provide top-quality Needle Roller Bearings that meet stringent industry standards. The NA 6909 is designed for demanding environments, offering reliable performance and a long service life in a variety of industrial and automotive machinery. Its construction is ideal for applications requiring precision, strength, and a compact footprint.
Key Features of the NA 6909 Bearing
- High Radial Load Capacity: Engineered with needle rollers to support heavy radial forces.
- Compact and Space-Saving Design: Low cross-sectional height is ideal for radially constrained applications.
