High-force industrial cylinder designed for heavy-duty linear motion applications. Features dual adjustable air cushions for smooth deceleration and anti-vibration design. The hard chrome rod with triple sealing system ensures reliable operation in dusty environments. Requires 40μm filtered lubricated air (ISO 8573-1 class 4).
- Press machine ejection systems
- Automotive welding fixture positioning
- Steel coil handling equipment
- Plastic injection molding machine clamps
- Paper roll lifting mechanisms
Installation guidelines:
Maintain ≤0.1mm/m alignment tolerance during mounting. For vertical installations,
use rod-down orientation to prevent seal wear. Lubricate through air ports using
ISO VG32 turbine oil before initial operation.
Critical note:
Avoid side load exceeding 150N. When stroke ≥800mm, mandatory use of intermediate
support brackets is required to prevent rod deflection. Maximum permissible
lateral play: 0.5mm at full extension.
