High-thrust industrial cylinder designed for heavy-duty automation applications. Features dual chrome-plated piston rod (hardness HRC 45-55) and precision honed aluminum barrel with oxidation-resistant treatment. The TC mounting variant provides stable fixation for vertical/horizontal force transmission. Requires 40μm filtered air and ISO VG32 hydraulic oil lubrication (optional oil-free operation).
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Construction material compression molds
- Waste baling machine actuators
- Shipbuilding jig alignment mechanisms
Installation guidelines:
Maintain 0.05-0.15mm alignment tolerance during mounting. Apply initial lubrication (30-40 drops of oil) through air ports before first use.
Allow 50mm rear clearance for cushion adjustment. Anti-rotation lock nuts (M36) require 220N·m torque.
