Industrial-grade heavy-duty cylinder designed for precision stroke control in high-load applications. Features dual-stage shock absorption with hydraulic cushioning adjustment screws at both ends. The steel pipe construction ensures superior rigidity for lateral force resistance, while the chrome-plated piston rod withstands over 10,000km of reciprocation cycles. Requires 40μm filtered air with 1-2 drops of ISO VG32 turbine oil per m³ for optimal lubrication.
- Press machine ejection systems (plastic injection molding)
- Shipbuilding fixture positioning mechanisms
- Steel coil handling equipment in rolling mills
- Automotive welding line clamping devices
- Foundry mold core pulling operations
Installation requirements:
Maintain 0.05-0.15mm clearance between guide bushing and load guide rail.
Lubricate adjustment screws with Molykote EM-30L grease monthly.
Max side load: 1,800N at mid-stroke. Always install rod-end support when stroke exceeds 400mm.
