High-torque industrial cylinder optimized for heavy-duty linear motion applications. Features dual anti-rotation guide rods (12mm diameter) and wear-resistant rod bearing for precise axial alignment. The nickel-plated end caps provide enhanced corrosion resistance in humid environments. Requires 40μm filtered compressed air with dew point -25℃ below ambient.
- Automotive press line material handling systems
- Foundry equipment core-pulling mechanisms
- Shipbuilding plate bending machine actuators
- Heavy conveyor gate control in mining operations
- Plastic injection molding machine ejectors
Maintenance Protocol:
Perform axial load alignment checks every 5,000 cycles. Use shim washers when mounting
to prevent housing distortion (max 0.1mm parallelism deviation). Buffer adjustment
should be set to 2/3 stroke position for optimal energy absorption.
