Precision-engineered medium-bore cylinder featuring dual anti-rotation design and corrosion-resistant surface treatment. The hexagonal body structure enables wrench tightening (SW19) during installation. Integrated magnet slots (D-M9B) allow position sensor integration. Special wear ring design achieves ≤0.5mm/s low-speed stability.
- Clamping fixtures in CNC machining centers
- Ejection mechanisms for injection molding machines
- Valve actuation in food processing lines
- Paper feed systems in printing equipment
- Positioning stages in semiconductor handling
Maintenance protocol:
Lubricate with ISO VG32 hydraulic oil initially, then replenish 1-2 drops of turbine oil (ISO VG15) every 50km of cumulative stroke. Avoid lateral loading exceeding 30N·m. For vertical mounting, use rod-down orientation with ≤0.3MPa pressure reduction.
