A heavy-duty industrial cylinder optimized for high thrust applications requiring precise linear motion. Features wear-resistant construction with integrated shock absorption and corrosion-resistant coatings. The TC mounting variant provides enhanced stability for vertical or inclined installations. Requires ISO VG32 hydraulic oil lubrication if used in high-cycle (>5Hz) operations.
- Metal stamping press ejection systems
- Automotive welding fixture positioning
- Plastic injection molding machine core pulls
- Heavy conveyor gate actuators
- Paper mill roller engagement mechanisms
Installation note:
Maintain 0.05-0.1mm alignment tolerance during mounting. Lubricate rod ends weekly
with MIL-PRF-6085 grease in dusty environments. Avoid side load exceeding 15% of
maximum thrust capacity.
