LM 20UU OP | XIC | Linear Motion Bearing | LM-OP Series

The LME 16 UU is a closed‑type linear ball bearing designed to run along a 16 mm shaft, delivering smooth, low‑friction linear motion for machines and mechanisms that require shaft‑guided translation. It has an inner bore (shaft diameter) of 16 mm, an outer diameter of 26 mm, and a housing length of 36 mm. Inside, it contains five rows of steel balls held in a resin retainer, which roll on precision‑ground inner raceways to ensure smooth, vibration‑free motion with minimal friction. The bearing is sealed on both ends (“UU” = double-side rubber seals), which helps keep out dust, dirt, and moisture, extending operational life and reducing maintenance efforts. Its hardened steel outer sleeve provides rigidity and wear resistance under repeated load cycles. In terms of load capacity, the LME 16 UU offers a basic dynamic load rating around 578 N and a static load rating about 892 N. Because of its compact size, sealed design, and reliable linear‑motion performance, this bearing is commonly used in CNC machines, 3D printers, automation equipment, and other machinery where accurate, stable, shaft‑guided linear motion is required.
