High-precision double rod cylinder engineered for bidirectional force applications requiring exceptional rigidity and alignment accuracy. Features symmetrical load distribution through twin piston rods and dual guide bearings, minimizing deflection during operation. The hard chrome-plated piston rods and corrosion-resistant construction ensure durability in humid environments.
- Precision press-fitting operations in automotive assembly
- Vertical lifting mechanisms for CNC material handling
- Synchronized clamping systems in injection molding
- Paper feed control in high-speed printing machinery
- Positioning stages for optical component manufacturing
Installation guidelines:
Maintain parallel alignment within 0.2mm/m tolerance. Use floating joints
to compensate for minor misalignment. For vertical installations,
always install air vents upward. Recommended air filtration: 5μm with
auto-drain function. Lubricate using ISO VG32 hydraulic oil if extended
storage occurs.
Critical note:
Avoid side load exceeding 30N. Maximum allowable moment: 18Nm.
When used in tandem configurations, synchronize pneumatic circuits
using flow control valves to prevent differential movement.
