LME 30 UU | XIC | Linear Motion Bearing | LME Series

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.
