Product Overview: The NA 6905 Needle Roller Bearing
The NA 6905 is a high-capacity machined ring needle roller bearing with an inner ring, featuring dimensions of 25x42x30mm. As a key component in our NA Series, this bearing is designed for applications demanding high radial load-carrying capability within a compact design. The inclusion of a precision-ground inner ring allows it to be used on shafts that are not hardened, providing a versatile and cost-effective solution for various engineering challenges. This bearing is part of our comprehensive range of Needle Roller Bearings, manufactured to stringent industry standards to ensure reliability and optimal performance in demanding industrial environments.
Features of the NA 6905 Bearing
- High Radial Load Capacity: Engineered with a full complement of rollers to support heavy radial loads.
- Compact and Rigid Design: The low cross-sectional height saves space, while the machined outer ring provides high rigidity.
- Includes Inner Ring: Allows for use on standard shafts without the need for special hardening or grinding, reducing overall system cost.
- Cage-Guided Rollers: The cage ensures proper roller guidance, making it suitable for higher speed applications compared to full complement designs.
- Precision Engineering: Manufactured for dimensional accuracy, ensuring a proper fit and reliable operation.
- Separable Components: The inner ring, outer ring, and needle roller cage assembly can be mounted separately, simplifying installation.
Applications of NA 6905 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling high torque and loads.
- Automotive Transmissions: Used in transmission systems where space is limited but high load capacity is essential.
- Construction Equipment: Ideal for pivot points and linkages in heavy machinery like excavators and loaders.
- Two-Stroke Engines: Commonly found in connecting rods and crankshafts due to their high performance in oscillating conditions.
- Pumps and Compressors: Ensures reliable rotation and support for critical components.
- Agricultural Machinery: Withstands the demanding and often contaminated environments of farming equipment.
- Machine Tools: Used in spindles and other precision assemblies requiring high stiffness and accuracy.
