Ultra-compact stainless steel cylinder with dual adjustable rods, designed for precision linear motion in corrosive environments. Features a unique "step-less stroke adjustment" mechanism allowing 0-500mm stroke fine-tuning via lock nuts. The symmetrical dual-rod design eliminates rotational torque for stable payload guidance. Mirror-polished rods (Ra≤0.4μm) prevent particulate contamination.
- Cleanroom automation in semiconductor manufacturing
- Chemical dosing systems with aggressive media exposure
- High-cycle packaging lines requiring stroke flexibility
- Marine equipment actuators with saltwater resistance
- Pharmaceutical tablet press ejection mechanisms
Installation tip:
Use anti-seize compound on stainless steel threads. For full stroke adjustment range,
maintain 15mm minimum engagement on both rod threads. Lubricate with ISO VG32
hydraulic oil for food-grade applications.
Critical note:
Avoid side loads exceeding 15N·m. When used in vertical orientation,
install mechanical brake or counterbalance valve. Maximum lateral
misalignment tolerance: ±0.2mm at rod ends.
