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

Description LM 30 UU Linear Ball Bearing The LM 30 UU is a single-row linear ball bearing designed for smooth, precise motion along a shaft in automation systems, CNC machines, 3D printers, and other linear motion applications. The “UU” suffix indicates that the bearing has metal shields on both sides, which protect the balls and internal raceways from dust and debris while retaining lubricant for longer service life. Its robust construction ensures low friction, smooth travel, and accurate positioning even under moderate radial loads. Inner Diameter (Shaft Size): 30 mm Outer Diameter: 42 mm Length (Housing Length): 50 mm Sealing: Metal shields on both sides (UU) Bearing Type: Single-row linear ball bearing Material: Hardened steel balls and steel raceway Applications: CNC machines, linear actuators, 3D printers, automation systems Features: Low friction, smooth linear motion, moderate load capacity, dust protection
