Product Overview: The NA 4910 Needle Roller Bearing
The NA 4910 is a high-precision machined ring needle roller bearing designed for applications demanding high radial load capacity within a compact design. With principal dimensions of 50x72x22mm (Bore x Outer Diameter x Thickness), this bearing is a key component in our NA Series. It features a robust machined outer ring and comes complete with an inner ring, making it suitable for use on shafts that are not hardened or ground. This versatility simplifies design and assembly processes in various industrial settings.
As part of our extensive range of Needle Roller Bearings, the NA 4910 is engineered to provide superior performance where radial space is limited. The cage-guided rollers ensure smooth operation, reduced friction, and suitability for higher speeds compared to full complement designs. Trust our expertise as a leading supplier of industrial bearings to provide reliable and durable components like the NA 4910 for your most demanding machinery.
Features of the NA 4910 Bearing
- High Radial Load Capacity: The line contact of the needle rollers allows for excellent distribution of heavy radial loads.
- Compact and Space-Saving: Its low cross-sectional height makes it ideal for applications with limited radial space.
- Includes Inner Ring: Allows for use with shafts that are not specially heat-treated or ground, offering greater design flexibility.
- Machined Outer Ring: Provides high rigidity and dimensional accuracy, ensuring a precise fit in the housing.
- Cage-Guided Rollers: The cage prevents roller-to-roller contact, reducing friction and heat generation, which allows for higher operational speeds.
- Durable Construction: Manufactured from high-quality bearing steel for enhanced durability and a long service life under tough conditions.
