The LME 10 UU is a compact linear‑ball bearing (often called a linear bushing) designed to slide smoothly along a 10 mm shaft for precise, low‑friction linear motion. The “10” refers to its inner bore (shaft diameter) of 10 mm, while “UU” indicates that the bearing is sealed on both ends with rubber/dust seals — which helps prevent contamination from dust, dirt, or moisture. Internally, it features four rows of steel balls retained by a resin retainer, allowing the balls to roll along the shaft with minimal friction. The bearing has an outer diameter of 19 mm and an overall length of 29 mm, making it small and lightweight (≈ 0.03 kg) but suitable for linear‑motion tasks requiring compact size and precision. Its dynamic load rating is about 372 N and static load rating about 549 N. The sealed design and ball‑circulation mechanism make it ideal for applications such as small CNC machines, 3D printers, linear actuators, robotics, or automation equipment — wherever accurate, smooth linear movement along a round shaft is needed and contamination protection is important.
