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.

NUTR 3072 — Track Roller / Yoke‑Type Support Roller

The NUTR 3072 is a yoke‑type track roller bearing designed for heavy‑duty cam, guide‑way or conveyor‑type industrial applications. It has a 30 mm inner bore, a 72 mm outside (roller) diameter and an overall width of 29 mm (outer‑ring width ~28 mm). 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.

NUTR 1747 — Track Roller / Yoke‑Type Support Roller

The NUTR 1747 is a yoke‑type track roller bearing (support/track roller) with an inner ring and sealed outer ring — ready to install without requiring a hardened shaft. It is built around a full‑complement, double‑row cylindrical‑roller assembly and a thick‑walled outer ring with a crowned running surface, which helps the bearing tolerate misalignment or skew and operate smoothly even under heavy radial loads or shock loads. Because the bearing is sealed and includes a lubrication‑hole in the inner ring, it’s well‑suited for conveyor rails, cam‑drives, guide‑rails and general track‑guided mechanical applications, offering high load capacity, reliable long service life, and easy maintenance.
