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.
PB 6
The PB 6 is a miniature spherical plain bearing designed for small-shaft applications where compact size and smooth rotation with angular accommodation are required. With a 6 mm bore, 18 mm outer diameter, and 9 mm width, PB 6 is ideal for very compact linkages, small actuators, or light mechanical pivots. It supports a dynamic radial load of approximately 4.3 kN and a static radial load of around 9.8 kN, sufficient for light-load conditions or delicate link mechanisms. The bearing’s hardened inner spherical ring and durable outer ring provide reliable sliding contact and resistance to wear, even during repeated cycles of motion. PB 6 is especially useful for small-scale automation, mechanical linkages, or lightweight pivot joints where space is limited but smooth, stable movement is critical.
PB 8
The PB 8 is a small spherical plain bearing suitable for light to moderate radial loads and small-shaft applications. With an 8 mm bore, 22 mm outer diameter, and 12 mm width, it fits in tight spaces while offering reliable rotational and angular motion. It supports a dynamic radial load around 6.8 kN and a static radial load near 16 kN, making it appropriate for small linkages, hinges, or pivot points in machinery, automation systems, or light mechanical assemblies. Its steel outer ring and hardened inner spherical surface provide durability and stable sliding contact, even under repeated motion. PB 8 is particularly useful where compact size and smooth pivoting under load are needed.
PB 10
The PB 10 is a compact spherical plain bearing designed to allow smooth rotational and slight angular motion between a shaft and housing while supporting moderate radial loads. With a 10 mm bore, 26 mm outer diameter, and 14 mm width, this bearing is suitable for small to medium-sized mechanical linkages, pivots, or oscillating joints. Its steel outer ring combined with a hardened spherical inner ring ensures durability and wear resistance under load. PB 10 is well-suited for light machinery, linkage systems, pneumatic or hydraulic actuators, or any mechanical system where compact spherical plain bearings are required.
PB 18
The PB 18 is a robust spherical plain bearing designed to accommodate both rotational and angular motion while supporting substantial radial loads. With an 18 mm bore, 42 mm outer diameter, and 23 mm overall width, it offers a compact yet sturdy profile suitable for mechanical linkages, pivots, suspension arms, and oscillating components. Its spherical inner design allows tilting or angular misalignment up to approximately 15°, making PB 18 especially useful in assemblies where alignment varies during motion. Constructed from high-carbon steel and bearing-grade materials, PB 18 provides high strength and durability under demanding operational conditions. With a dynamic load capacity of around 25,700 N, this bearing is ideal for heavy-duty applications where reliability, smooth articulation, and resistance to wear are required, such as in agricultural machinery, industrial linkages, hydraulic systems, and mechanical suspension components.
ST 162837 B
The ST 16 B is a small, lightweight linear ball bushing designed for smooth linear motion on 16 mm shafts. With a 16 mm bore, 28 mm outer diameter, and 37 mm length, this bearing is ideal for compact linear guide systems, light automation setups, and precise motion mechanisms. Its dynamic load capacity of approximately 1,910 N and static load rating of about 1,980 N make it suitable for light to moderate loads. The ST 16 B’s compact size and efficient design provide reliable, low-friction linear movement where space is limited and accurate, repeatable motion is required.
ST 203245 B
The ST 20 B is a compact linear ball bushing designed for smooth, low-friction linear motion along a 20 mm diameter shaft. With a 20 mm bore, 32 mm outer diameter, and 45 mm length, it is ideal for light-to-medium duty linear guides, automation equipment, and small-scale mechanical systems.
