Description
LRM Miniature Linear Guide
1. Stainless steel construction with high rigidity, enabling shared guide rails across same-type carriages
2. Anti-drop ball bearing retention mechanism for simplified installation and replacement
3. Japanese-manufactured steel balls ensuring superior sphericity and wear resistance (ISO3290 G10 compliant)
4. Enhanced oil-scraping wipers and upgraded dust-proof sealing system
5. Streamlined profile with concealed fasteners protecting sealing strips and eliminating large particulate contamination
Category: Linear Guides | Brand: AirTAC | Series: LRM
Maintenance Note:
Relubricate every 100km travel using ISO VG15 grease. Avoid mixing
grease types. Use 0.15-0.25N·m torque for mounting screws with Loctite 243.
