About this product

Shandong Bote JSA-LG20Z is a standard rectangular ball linear guideway in the LG-ZL family, a guide range the manufacturer identifies for industrial robots and precision instruments. Its published dimensions include 30 mm assembled height, 20 mm rail width and 70 mm slider length. The source lists rated-load symbols C/C0 as 13.6/22.7 kN, with separate directional static-moment ratings. Rail length, slider quantity, seals and preload remain order selections; the longer C-block models are separately accounted. Cover image: Manufacturer series image; size may vary.
