Heavy-duty twin rod cylinder engineered for precision linear motion control requiring enhanced rigidity and alignment stability. Features dual guide rods that eliminate rotational movement, with micrometer-grade stroke adjustment via 20mm threaded limit collars. The hardened piston rods and triple-lip seals ensure durability in high-side-load applications.
- CNC machine tool clamping/fixturing systems
- Automated material handling with precise position locking
- Glass cutting/polishing equipment requiring vibration-free operation
- Automotive assembly line positioning arms
- High-precision packaging machinery with space constraints
- Align within 0.2mm/m perpendicularity tolerance for optimal rod bearing life
- For vertical mounting, use auxiliary rod supports when stroke exceeds 150mm
- Adjust cushion screws gradually (1/4 turn increments) for smooth deceleration
- Maintain air quality: 40μm filtration with ISO 8573-1:2010 Class 4.4.2 standard
