NA 4904
The NA 4904 is a single‑row needle roller bearing with a machined outer ring and inner ring, featuring flanges on the outer ring for axial guidance. Its compact, low‑cross‑section design allows it to support high radial loads with stable rotation, making it ideal for gearboxes, pumps, motors, and other mechanical assemblies where space is limited. Thanks to its robust steel construction and dense needle‑roller configuration, the NA 4904 delivers dependable performance and long service life even under continuous or heavy‑duty conditions.

NKI 1516
The NKI 1516 is a machined‑ring needle roller bearing with inner ring, providing a hardened raceway independent of the shaft — which means it can be used even if the shaft is not specially treated. It offers excellent radial load capacity while maintaining a compact cross‑section, making it ideal for gearboxes, small motors, and industrial machinery requiring low-profile bearings. The needle‑roller and cage assembly ensures smooth rotation, good rigidity, and reduced friction under load
NA 6905
The NA 6905 is a needle roller bearing with a machined inner ring and flanges on the outer ring, designed for applications where high radial load capacity and compact cross-section are required. Its many small-diameter needle rollers provide excellent rigidity and load distribution, which makes this bearing suitable for industrial gearboxes, pumps, electric motors, and other heavy-duty machinery. The design allows for smooth rotation, low friction, and good durability under continuous or heavy loads — ideal where shaft grinding or hardening is impractical. Made of high-grade bearing steel, NA 6905 delivers reliable performance and a long service life when properly lubricated and installed.
NA 4909
The NA 4909 is a machined‑ring needle roller bearing with an inner ring, designed to deliver high radial load capacity while still maintaining a relatively low cross‑section — making it ideal for applications where radial space is limited but load demands are significant. Its dense arrangement of needle rollers provides high stiffness, good load distribution and smooth rotation under load. The outer ring includes flanges for axial guidance, and the bearing’s design offers stable, reliable service even under continuous or heavy loads. This makes the NA 4909 suitable for industrial gearboxes, pumps, transmissions, and other heavy‑duty mechanical systems where compactness and durability matter.
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.
