Airtac MKD Multi-position Clamping Cylinder MKD20X20
The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD20X20 is a genuine MK multi-mount cylinder (double rod), 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. As an MK unit a fixed rod stops the piston rod rotating.

About the Airtac MKD Multi-position Clamping Cylinder MKD20X20
The MKD20X20 is an AirTAC MK-series multi-mount cylinder: a compact square body that fixes from 6 directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space. As the MKD double-rod variant it offers a rod on both sides of the body, and as an MK cylinder it is no-rotating, with a plate and fixed rod keeping the rod from turning under load. The 20 mm bore delivers a theoretical 157.1 N push and 131.9 N pull at 0.5 MPa, with a bumper cushion and operation on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi).
This is a genuine AirTAC part from an authorized distributor. In the MD family the rod may rotate; the MK family prevents it - pick MK when your load must stay square. This SKU has no trailing S, so it is supplied WITHOUT a magnet; if you need proximity-switch sensing on the body slots, choose an S version instead. Exact body dimensions depend on the stroke, so confirm the 20 mm stroke envelope from the datasheet - we are glad to help with 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
Size the 20 mm bore for roughly 157.1 N of push (131.9 N pull) at 0.5 MPa. MKD combines the no-rotating MK construction with a double rod, giving you an actuation point at each end - handy for symmetric clamping or push-pull from either side. This unit is a plain MKD20X20: 20 mm stroke, double acting, PT ports at M5x0.8, and no magnet (no S suffix). An S-version adds the magnet if you later need position feedback. Keep strokes modest on these short-cover bodies; an over-long stroke can strain the arrangement, so check any longer option with us. Side-load figures are not stated here - route those to the datasheet.
Applications
Fixture clamping from either side
The double-rod body lets one cylinder clamp or eject from both ends, so a 20 mm bore unit can serve two small clamping points in a tight fixture without rotating the rods.
Vertical gate actuation
Mounted from the top or bottom face, the no-rotating rod drives a slide or gate straight up or down without twisting, ideal for compact diverters beside conveyors.
Stopper pins on pallet lines
With the rod held square by the fixed rod and plate, a stopper pin rises and drops without rotating, keeping pallet location repeatable in space-constrained cells.
FAQ
Does this MKD20X20 include a magnet for proximity switches?
No. This SKU has no trailing S, so it is supplied WITHOUT a magnet. The body does have magnetic-switch slots, so if you want position sensing, order an S version such as MKD20X20S. The MK body is otherwise identical: no-rotating double rod, 20 mm bore, 20 mm stroke, PT-threaded M5x0.8 ports.
Where can I mount this cylinder, and what loads can the rod take?
The square body fixes from 6 directions - front, back, left, right, top and bottom - and cylinders mount side by side to save space, with switch slots around the body. Cushioning is a bumper. Side-load capacity is not quoted here as a number, and overall dimensions change with stroke, so confirm both from the datasheet or ask us.
