The SCD250X450S industrial cylinder delivers 19.6kN thrust force at 0.5MPa, designed for heavy-duty linear motion applications. Features dual adjustable cushions for smooth deceleration and reduced impact noise. Corrosion-resistant construction with hardened piston rod surface (HRC 35-40) ensures durability in harsh environments. Requires 40μm filtered air with ≤5% relative humidity.
- Metal stamping press ejection systems
- Automotive assembly line clamping units
- Construction machinery boom actuation
- Waste compaction equipment
- Shipbuilding fixture positioning
Installation note:
Align cylinder axis within 0.2mm perpendicularity tolerance. For vertical mounting,
add mechanical lock nut on piston rod thread. Allow 1.5× bore size clearance
for cushion sleeve adjustment.
