Constructed from high-quality bearing steel, it is ideal for automotive gearboxes, industrial machinery, and mechanical linkages where precise rotation and durability are essential.
NKIA 5903
The NKIA 5903 needle roller bearing features an inner ring and is designed for compact, high-load applications. With a 17 mm bore, 30 mm outer diameter, and 25 mm width, it provides smooth rotation and excellent radial load support. Made from durable bearing steel, this bearing is ideal for transmissions, gearboxes, and other machinery requiring precision, reliability, and long-lasting performance.
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.

Its dense assembly of fine rollers ensures good load distribution, high stiffness, and smooth rotational performance even under heavy or continuous load. The compact profile and rugged steel construction make it suitable for gearboxes, pumps, automotive components, and general machinery needing reliable and durable bearing support.
NUTR 2562 — Track Roller / Yoke‑Type Support Roller
The NUTR 2562 is a yoke-type track roller bearing designed for heavy-duty industrial applications, such as cam-follower systems, conveyor guides, and linear motion tracks. It features a 25 mm inner bore, a 62 mm outer diameter, and an overall width of 25 mm, with a 24 mm wide outer ring. Internally, it uses a double-row, full-complement cylindrical roller configuration, providing excellent radial load capacity and resistance to shock. The outer ring has a crowned surface to accommodate minor misalignments, and the bearing comes sealed on both sides, often with provisions for relubrication. It has a basic dynamic radial load rating of approximately 35.8 kN and a static load rating around 48 kN, with a maximum recommended speed of roughly 3200 rpm when grease-lubricated. Its robust construction, high load tolerance, and sealed, ready-to-mount design make the NUTR 2562 ideal for demanding industrial environments requiring durability, reliability, and smooth rolling performance under heavy loads.
NUTR 4090 — Track Roller / Yoke‑Type Support Roller
The NUTR 4090 is a yoke‑type track roller bearing (support roller) built for heavy‑duty industrial applications such as cam‑follower systems, conveyor tracks, guideways, and other machinery requiring a bearing to run directly on a track or rail. It has a 40 mm bore (inner diameter) and a 90 mm outer (roller) diameter, with a total width of 32 mm (outer‑ring width ~ 30 mm). Internally, the bearing uses a double‑row full‑complement of cylindrical rollers (i.e. many rollers, no cage), which gives it high radial load capacity and good shock resistance. The outer ring has a crowned running surface — this helps the roller to run smoothly on a track and tolerate slight misalignments or tilts.
The NUTR 4090 is supplied sealed on both sides (labyrinth/contact seals), and includes internal lubrication provisions (relubricatable by grease), which increases reliability and life in industrial use. In terms of load‑carrying capability: its basic dynamic radial load rating is roughly 68.2 kN and the static radial load rating around 91.5 kN. Its maximum recommended operating speed under grease lubrication is about 1,600–1,800 rpm, reflecting the full‑complement design (which tends to limit high‑speed capability but improves load capacity and durability).
Because of these characteristics — thick‑walled outer ring, crowned surface, full‑complement rollers, seals and relubrication — NUTR 4090 is ideal where high radial loads, durability, long life and smooth track‑rolling under heavy load are required. Typical applications include conveyors, cam‑drives, linear guides, material‑handling equipment, printing or packaging machines, and other industrial systems where parts roll or slide on tracks rather than rotate on a shaft.
