Guide cylinder EN series double piston pneumatic cylinder, double force, bore sizes range 10mm-32mm. Cylinder body, front cover and mounting plate of the pneumatic cylinder are simultaneously machined in Horizontal machining center, which gives strong guarantee for extremely high precision and concentricity. The double piston pneumatic cylinder has high bending resistance and tensional strength performance with non-return precision and low piston rod deflection, well supporting lateral loading performance. With elongated slide supporting guide, no extra lubrication is needed with better guiding performance for the double piston cylinder. The cushion pad of front cover gives a good adjustment for cylinder stroke and better impact power reducing down. Two sets of IN/OUT ports are available for more suitable choice, while 3 sides are designed with suitable mounting holes.
