Heavy-duty industrial cylinder designed for high moment load applications requiring precise linear motion. Features wear-resistant bronze bushings and triple sealing system (rod wiper + primary seal + rod seal). Optional auto switch grooves accommodate multiple sensor types (inductive, reed). Corrosion-resistant construction with IP65 protection rating.
- Press machine ejection systems
- Automotive welding fixture positioning
- Steel coil handling equipment
- Plastic injection molding clamp units
- Paper roll lifting mechanisms
Installation guidelines:
Ensure proper rod alignment (max 0.2° angular misalignment). Use SAE VG32 hydraulic oil for lubrication.
Allow 20mm clearance around cylinder body for heat dissipation. Magnetic sensors require 18-30VDC power supply.
Maintenance alert:
Replace cushion seals every 500,000 cycles in high-speed applications. Avoid side load exceeding 220N·m.
Always exhaust through speed controller during adjustment.
