Airtac MD Multi-Position Clamping Cylinder MD20X80
The AirTAC Airtac MD Multi-Position Clamping Cylinder MD20X80 is a genuine MD multi-mount cylinder (double acting), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MD Multi-Position Clamping Cylinder MD20X80
The AirTAC MD20X80 is a 20 mm bore, 80 mm stroke, double acting multi-mount cylinder. Multi-mount bodies fix from six directions - front, back, left, right, top and bottom - and can be mounted side by side to save space, with magnetic-switch slots machined around the body and high guide precision without added lubricant. At 0.5 MPa this bore delivers about 157.1 N of theoretical push force, enough for clamping, stopping and positioning light parts, and the bumper cushion absorbs end-of-stroke impact.
This is a genuine AirTAC part from the MD family, the standard multi-mount cylinder; rod rotation is allowed, with the MK family covering no-rotating needs. The SKU carries no S suffix, so it is supplied without a magnet. Note that the standard stroke table lists bore-20 double acting models up to 60 mm, so confirm the 80 mm stroke build and its overall dimensions from the datasheet - we can provide sizing on request.

Specifications follow the official AirTAC MD/MK multi-mount data. The front cover and piston are short, so avoid an over-long stroke. An optional high-temperature seal material extends the range to 0 to 150 C. Overall dimensions vary per stroke and allowable side-load is published as curves — ask us and we confirm from the datasheet.
How to choose
Choose the bore for thrust: 20 mm gives 157.1 N theoretical push at 0.5 MPa, double acting; step up to 25 mm (245.4 N) or 32 mm (402.1 N) for more force. This SKU is double acting - air drives the rod both ways. Its 80 mm stroke is longer than the up-to-60 mm range listed for bore-20 double acting models, so confirm the extended-stroke option from the datasheet before ordering; a long stroke on a short body is more exposed to side load, which we can review with you. No S suffix means no magnet; specify S if you need switch detection. Thread is PT as standard; G is available. Side-load figures are not stated here - confirm from the datasheet.
Applications
Vertical part lift
The 80 mm stroke lifts small parts between two levels of an assembly fixture, with the compact body fixed from the top or bottom plate.
Conveyor gate stopper
Extends across a conveyor lane to stop products at a workstation; side-by-side mounting keeps a row of stoppers on close centres.
Jig positioning
Pushes a workpiece against a jig locator before clamping, with the cylinder bolted from whichever of the six body faces suits the fixture.
FAQ
Why does the 80 mm stroke need checking on a 20 mm bore?
AirTAC's standard stroke table lists bore-20 double acting models up to 60 mm, and MD20X80's 80 mm stroke is outside that range. Confirm the extended-stroke build and its dimensions from the datasheet before ordering. A long stroke on a short body is also more exposed to side load, which we can check for you.
What does the missing S mean on MD20X80?
No trailing S means the cylinder is supplied without a magnet. If you want to fit magnetic switches into the slots around the body, order the S version instead. The port on a 20 mm bore is M5x0.8 with PT thread as standard, and operating pressure is 0.15-1.0 MPa (22-145 psi).
