Compact cylinder for precision testing
The Festo DMM-20-50-P-A is a compact cylinder with a 50 mm stroke designed as test equipment for electricians and automation technicians. It delivers controlled linear movement in a small footprint, making it suitable for bench testing, fixture actuation and prototype validation where space is limited.
Replaces larger actuators in tight setups
This cylinder upgrades from bulkier pneumatic units when a 50 mm stroke is sufficient and mounting envelope is constrained. The jump is worth it when the application demands repeatable positioning without the bulk of standard bore sizes, reducing fixture weight and cycle time in confined cells.
Simple pneumatic installation
Installation uses standard pneumatic ports and threaded body mounting; connect filtered compressed air, align the load axially and secure the cylinder. Misalignment or side loading on the piston rod is the most common cause of premature seal wear and erratic stroke behaviour.

Questions about this item
What mounting dimensions does the DMM-20-50-P-A compact cylinder require?
The cylinder uses a 20 mm bore and 50 mm stroke; check the 158528 datasheet for exact flange or thread pattern before drilling.
Which installation step is most often missed when fitting this compact cylinder?
Align the piston rod to the load centreline and torque the mounting bolts to the specified value; misalignment causes premature seal wear.
When should the seals on this cylinder be inspected or replaced?
Plan a seal inspection after three years of service or one year of heavy cycling; the parts warranty covers three years and labour one year.
