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.
