The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD20X5 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.
The MKD20X5 is a genuine AirTAC multi-mount cylinder from the MK family: a compact square-body unit fixed from 6 directions (front, back, left, right, top and bottom) that mounts side by side with other units to save space, with magnetic-switch slots around the body. This double-rod, double-acting, no-rotating model has a 20mm bore with a rod-side theoretical thrust of 131.9 N at 0.5 MPa and a very short 5mm stroke, cushioned by a bumper.
The no-rotating plate, bushing and fixed rod of the MK build stop the rod from turning, which keeps small pads and pins pointing exactly where you set them. The trailing S confirms the magnet is fitted on this SKU, and the thread is PT with a G option. The 5mm stroke uses short covers, so dimensions are per the datasheet; we confirm them 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.
Match the 20mm bore's 131.9 N rod-side theoretical thrust at 0.5 MPa to your load before selecting. MKD double rod gives you a working rod end on both sides of the body, and MK is the family to pick when the rod must never rotate. The 5mm stroke is well inside the 20mm bore table (up to 60mm), but very short strokes like this are built with short covers: keep the application genuinely short-travel and do not stretch beyond the coded stroke. This SKU includes the magnet (S), and PT threading can be ordered as G if needed.
A 5mm nudge is enough to slide a small finished part off a nest or fixture, and the double rod lets the same unit eject from either side of a tight station.
Mount the body vertically and lift a part or sensor flag by 5mm to confirm seating, with the no-rotating rod keeping the contact pad orientation fixed.
Bolt the compact body into a crowded jig and use the short stroke to clamp or release a delicate component where a longer cylinder simply will not fit.
Only if your job genuinely needs 5mm of travel, such as an eject, lift or micro clamp. Very short strokes use short covers on the compact body, and the cylinder should not be ordered with an over-long stroke beyond the bore's table; if you need more travel, step up within the 20mm bore table or ask us to size it from the datasheet.
A standard MD multi-mount cylinder allows the rod to rotate, which is fine for simple push-pull work. The MK family, including this MKD double rod, adds a no-rotating plate, bushing and fixed rod so the rod cannot turn, keeping pads, pins and fixtures aligned. Both mount from 6 directions and side by side.
