NA 4902

The NA 4902 is a single‑row needle roller bearing with machined rings, flanges on the outer ring, and an inner ring — designed to deliver high radial load capacity while maintaining a low cross‑sectional height, making it ideal for assemblies where radial space is limited. Its compact form factor and dense arrangement of fine rollers ensure smooth, precise rotation, high stiffness, and reliable load distribution under continuous or heavy-duty conditions. This bearing is commonly used in gearboxes, pumps, alternators, and other mechanical systems needing durable performance and efficient operation.

NA 4903

The NA 4903 is a single‑row needle roller bearing with machined rings and an inner ring, designed to deliver high radial load capacity while maintaining a low cross‑sectional profile. Its dense pack of needle rollers gives it high stiffness and excellent load distribution, making it suited for gearboxes, pumps, small motors, and other compact mechanical assemblies where space is limited but reliability is critical. The outer ring includes two integral flanges for axial guidance and typically features lubrication groove/holes to support maintenance and smooth operation under continuous load.

NA 4906

The NA 4906 is a single‑row needle roller bearing with machined rings and an inner ring, featuring flanges on the outer ring. Thanks to its dense set of fine needle rollers, it can support high radial loads while maintaining a low cross‑sectional height — ideal for compact mechanical assemblies such as gearboxes, pumps, electric motors, and other industrial machinery where space is limited but load demands are high. Its solid outer ring and steel cage construction provide durability, smooth rotation, and good resistance to wear under continuous or heavy‑duty operation.

NA 4907

The NA 4907 is a single‑row needle roller bearing with machined rings and an inner ring, featuring flanges on the outer ring to guide axial alignment. Its dense set of needle rollers provides high radial load capacity and good rigidity while keeping the bearing’s cross‑sectional height low — ideal for compact mechanical assemblies, gearboxes, pumps, and other industrial equipment where space is limited but load demands are high. Designed for durability and smooth rotation, NA 4907 performs well under continuous or heavy‑duty operation.

NA 4910

The NA 4910 is a single‑row, machined‑ring needle roller bearing with inner ring and flanged outer ring. It offers high radial load capacity and excellent stiffness while maintaining a low cross‑sectional height — making it suitable for compact mechanical assemblies, gearboxes, pumps, alternators, and other machinery where radial space is limited but load demands are high. The design allows for smooth, precise rotation, good load distribution, and easy relubrication thanks to lubrication groove/holes in the outer ring. Its robust construction ensures reliability and long service life under continuous or heavy‑duty operation.

NA 5910

The NA 5910 is a machined‑ring needle roller bearing with an inner ring, designed to deliver high radial load capacity while keeping a relatively low cross-section — making it well suited for compact mechanical systems, gearboxes, pumps, and other heavy‑duty industrial applications. Its robust needle‑roller configuration ensures smooth, precise rotation under load and effective load distribution, even in demanding conditions. The inclusion of a lubrication hole in the outer ring helps with maintenance and ensures consistent performance over long service life.

NA 6901

The NA 6901 is a single‑row needle roller bearing with machined rings and an inner ring; its design supports heavy radial loads while keeping a low cross‑sectional height, making it ideal for compact mechanical assemblies, gearboxes, pumps, and other industrial machinery. The dense array of needle rollers provides high load capacity, good rigidity, and smooth rotation under load. The outer ring features flanges for axial guidance, and the design allows for some axial displacement, useful in applications where shaft alignment or slight shaft movement occurs during operation. Made from bearing‑grade steel, NA 6901 delivers robust performance and long service life when properly lubricated.

NA 6902

The NA 6902 is a single‑row needle roller bearing with machined rings and an inner ring — engineered to deliver high radial load capacity while maintaining a low cross‑sectional height. Because of its dense arrangement of fine rollers and the flanged outer ring, it offers strong rigidity, smooth rotation, and reliable load distribution even in tight radial spaces. It’s commonly used in gearboxes, pumps, transmissions and other mechanical assemblies where compactness and high load capacity are required. The bearing is made from bearing‑grade steel and designed for durability, long service life, and efficient operation in demanding conditions.
