NSK LAS30CL Linear Guide
The NSK LAS30CL is a standard square-type (non-flanged) linear guide block from the LAS/LS series, designed for general industrial automation and precision machinery. It features a 4-row Gothic arch ball groove design (3-line grooves on each side) that delivers equal load capacity and rigidity in all four directions (up, down, left, right). This structure offers high rigidity, shock resistance, smooth motion, and excellent accuracy.
