Carriage Shift Cylinder Double-acting Hydraulic Cylinder
Product Overview
CDH1 MF3 series metallurgical grade mill type hydraulic cylinder designed for heavy-duty industrial applications. This double-acting cylinder features 80mm bore, 56mm rod, and 270mm stroke, built to ISO 6022 standards for reliable performance in demanding environments.
Key Features
- Viton (FKM) rod and piston seals rated for continuous fluid temperatures up to 150°C
- Compatible with HFA, HFC, and HFD fire-resistant hydraulic fluids per ISO 12922
- External metal wiper scraper prevents mill scale slag and metallic debris ingress
- Thermal radiation shield plate mounting bosses for installations near continuous casting mold zones
- MF3 round flange with 8-bolt pattern and precision machining for rigid alignment
- Double-hardened piston rod surface with induction case depth and hard chrome plating
- Integrated stroke limit proximity switch mounting groove for M12 inductive sensors
- 200+ hours salt spray resistance for aggressive mill cooling water environments
