LME 20 UU | XIC | Linear Motion Bearing | LME Series

The LME 8 UU is a compact linear ball bearing (a “linear bushing”) designed to slide along an 8 mm shaft, making it ideal for precise, low‑friction linear motion in small or lightweight systems. Its internal diameter (shaft size) is 8 mm, outer diameter 16 mm, and overall length is 25 mm. The bearing is of the closed type and sealed on both ends (“UU” designation), which helps prevent dust, dirt, and moisture from entering — thus enhancing durability and reducing maintenance. Inside, it uses four rows of steel balls held in a plastic (resin) retainer, allowing smooth, stable sliding along the shaft. Because of its small size and sealed design, LME 8 UU is well‑suited for compact machines such as desktop CNC machines, 3D printers, linear actuators, and other small automation or precision‑motion devices that require reliable linear guidance. Its combination of small footprint, low friction, and contamination protection makes it a popular choice for lightweight, precision linear motion applications.
