These double-acting hollow cylinders are used when the piston needs to be retracted quickly e.g. with high-cycle pulling applications. Features • Yale ChroMo-Design. • Operating pressure max. 700 bar. • Double-acting with hydraulic return. • With large centre hole diameter. • Cylinder body and piston are made from solid chromium-molybdenum steel and heat-treated. • Hard-chromium plated piston with replaceable, heat-treated saddle. • Metric mounting threads at cylinder body and inside of piston. • Stop ring prevents overtravel of the piston up to full operating pressure. • Interchangeable hardened saddle. • With inner and outer dirt wipers. • Oil port thread 3/8 NPT. • Incl. 2 female coupler halves model CFY-1. • All cylinders with carrying handle, from model YCH-62/250 with 2 lifting rings.
