High-precision industrial cylinder featuring wear-resistant chromium-plated rod and corrosion-resistant aluminum body. The dual adjustable pneumatic cushion minimizes impact at stroke ends, while the multi-lip seal design ensures <3mg/m leakage rate. Requires ISO 8573-1:2010 Class 3-4-3 compressed air.
- Automated assembly line clamping mechanisms
- Plastic injection molding ejector systems
- CNC machine tool chip conveyors
- Automotive welding fixture positioning
- Food processing conveyor gate actuators
Installation guidelines:
Align cylinder axis within ±0.5° deviation. Apply Molykote 111 lubricant
to rod before first use. Maximum side load: 45N. For vertical mounting,
use rod-down orientation to prevent condensate accumulation.
