Bottom Hydraulic Oil Cylinder

Product Attributes

Packaging & Delivery

Double-acting hydraulic cylinder are engineered for extreme thermal environments, featuring specialized heat-resistant designs that operate reliably in continuous 300-500°c temperatures near molten metal. Hydraulic cylinder for sale heavy-duty actuators incorporate multiple thermal protection systems including ceramic thermal barriers, high-temperature fluorocarbon seals, and water-cooled gland assemblies to maintain performance in steelmaking furnaces, glass tanks, and foundry applications. Industrial hydraulic cylinder deliver 50-2,000 ton thrust forces for precise furnace door operation, bottom electrode adjustment, or material pushing, with positioning accuracy within ±1mm despite radiant heat exposure. Their nickel-chromium alloy piston rods with plasma-sprayed alumina coatings resist scaling and oxidation, while graphite-impregnated bushings provide dry-running capability during cooling system interruptions.

Advanced models feature integrated heat pipes that actively dissipate thermal energy from critical seal areas, extending maintenance intervals to over 18 months in 24/7 operation. The compact designs minimize exposure area while providing full stroke lengths up to 3 meters for large furnace applications. Dual safety systems combine hydraulic holding valves with mechanical locks to prevent dangerous movement during power outages. Smart versions incorporate temperature and vibration sensors connected to predictive maintenance systems, alerting operators to abnormal conditions before failure occurs.
