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.

NK 1212
The NK 1212 is a machined‑ring needle roller bearing without inner ring. Its design assumes that the shaft itself will serve as the inner raceway (i.e. the shaft must be hardened/ground). This makes the NK 1212 very compact, low‑profile and suitable for light weight or space‑constrained applications where shaft treatment is already handled, such as small motors or compact gear assemblies.
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.
NKI 2530
The NKI 2530 belongs to the same series of needle roller bearings with inner ring; it is designed for heavier‑duty applications where larger shaft diameter is needed while still offering compact radial space usage. It is suitable for larger industrial gearboxes, conveyors, heavy machinery shafts, and other systems where strong radial load support and compact bearing profile are required.
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.
