Description

MB cylinder selection

MB cylinders provide double-acting pneumatic motion in 32–125mm bores. Choose the bore and stroke, mounting arrangement, port thread, cushioning and magnetic sensing options as a complete configuration. The pictured MBB50X75 is a basic-mount cylinder with 50mm bore and 75mm stroke.
