This ultra-flat cylinder features a remarkably compact profile (only 50mm body diameter) with 60% space savings compared to standard cylinders. The double-acting design with precision-machined aluminum construction ensures smooth operation in confined spaces. The adjustable air cushion mechanism minimizes end-impact noise while allowing precise stroke-end velocity control. The corrosion-resistant hard oxide coating makes it suitable for humid environments.

Maintenance tip:
Lubricate through air supply (ISO VG32 recommended) and perform monthly rod seal inspection when used in high-cycle applications (>500,000 cycles/year). Avoid side load exceeding 30N to prevent rod deflection.
