The LM 35 UU is a closed‑type linear ball bearing (also called a linear bushing) built to run smoothly along a 35 mm shaft for precise linear motion. It has an inner bore of 35 mm, an outer diameter of 52 mm, and a length (along the shaft) of 70 mm. Inside, it contains six rows of steel balls (ball circuits = 6), held in a plastic (resin) retainer, which roll along the shaft for smooth, low‑friction motion. The bearing’s body is made of hardened bearing steel, and it is sealed on both ends (“UU” = sealed both sides) to keep out dust, dirt, and moisture — reducing maintenance needs and improving durability. Its basic dynamic load rating is high (about 1670 N) and the static load rating about 3140 N, making it capable of carrying substantial loads while still enabling smooth linear motion. Because of its size, load capacity, and sealed design, LM 35 UU is commonly used in medium to large‑scale CNC machines, automation equipment, 3D printers, linear actuators, and other mechanical systems where stable, accurate, shaft‑guided linear motion under load is required.
The LME 25 UU is a closed-type linear ball bearing, also known as a linear bushing, designed to slide smoothly along a 25 mm shaft, providing precise, low-friction linear motion. The “UU” designation indicates that the bearing is sealed on both ends to protect against dust, dirt, and moisture, extending its service life and reducing maintenance. Internally, it contains six rows of steel balls retained in a polymer cage, allowing smooth, stable motion along the shaft. The bearing has an outer diameter of 40 mm, an overall length of 58 mm, and a total width of 44.1 mm. It has a basic dynamic load rating of approximately 980 N and a static load rating around 1570 N, enabling it to support moderate loads reliably. The sealed, closed design combined with hardened steel construction makes the LME 25 UU ideal for CNC machines, linear actuators, automation systems, 3D printers, and other equipment requiring precise, shaft-guided linear motion.
The LME 30 UU is a linear ball‑bushing bearing designed to provide smooth, low‑friction linear motion along a 30 mm shaft. The “UU” designation indicates that it is sealed on both ends with rubber seals to protect against dust, dirt, and moisture, extending the bearing’s operational life. It has an outer diameter of 47 mm and an overall length of 68 mm. Inside, it contains six rows of hardened steel balls held in a resin or plastic retainer, which roll along precision‑ground raceways to minimize friction while supporting the moving load. The bearing’s outer housing is made of hardened steel, giving it strength and rigidity for industrial applications. LME 30 UU is commonly used in CNC machines, 3D printers, automation equipment, robotics, and other machinery requiring stable, precise linear motion on a shaft. Its sealed, closed‑type design makes it particularly suitable for environments where contamination or debris could impair performance.
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.
