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.
NUTR 40 — Track Roller / Yoke‑Type Support Roller
The NUTR 40 is a yoke‑type track roller bearing (support‑roller / track‑roller) built for heavy‑duty industrial applications where parts run on tracks or guides. It has a 40 mm inner bore, an 80 mm outer (roller) diameter, and a total width of 32 mm (with the outer‑ring width around 30 mm). Internally, it uses a double‑row, full‑complement of cylindrical rollers (i.e. many rollers without a cage), which grants it high radial load capacity. The outer ring has a crowned running surface, and the bearing comes sealed on both sides (labyrinth‑seal or shielded), often pre‑lubricated — and in many versions it supports relubrication via the inner ring. The basic radial load ratings for NUTR 40 are on the order of 56–57 kN dynamic and 80 kN static, and the bearing can handle permissible dynamic radial loads around 31 kN under continuous operation. Its design — thick‑walled outer ring, sealed full‑complement rollers, crowned surface — allows it to tolerate heavy radial loads, some axial or skew loads (from misalignment or tilting), and to perform reliably in conveyor systems, cam‑follower assemblies, guide‑rails, linear motion tracks and other heavy‑duty industrial machinery where durability and smooth track‑rolling under load are needed.

Internally it uses a double‑row, full‑complement cylindrical roller set (i.e. many rollers without a cage) which gives it high radial load capacity and good resistance to shock and wear. The outer ring has a crowned running surface, helping ensure smooth movement and allowing some misalignment or skew between shaft and track. Like other NUTR rollers, it’s supplied sealed with labyrinth‑type seals on both sides, and includes a lubrication hole in the inner ring so it can be relubricated for extended life. Load‑rating data for NUTR 3072 shows a basic dynamic radial load capacity around 48.4 kN, and a basic static radial load capacity around 61 kN. Typical applications include cam‑follower systems, conveyor and guide‑rail systems, linear motion tracks, and other heavy‑duty industrial machinery where durability, reliability, and smooth rolling performance under load are required.
