The AirTAC Airtac MK Series Multi-position Locking Cylinder MK20X10S is a genuine MK 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. As an MK unit a fixed rod stops the piston rod rotating.
The MK20X10S is a genuine AirTAC multi-mount cylinder: a compact square-body actuator that can be fixed from 6 directions (front, back, left, right, top and bottom) and mounted side by side to save space. With a 20mm bore, 10mm stroke and double acting operation, it delivers about 157.1 N of theoretical push force at 0.5 MPa, and the cushion is a bumper. Magnetic-switch slots run around the body, guide precision is high, and no added lubricant is needed.
This is a no-rotating cylinder from AirTAC's MK family: a fixed rod, plate and brass bushing stop the piston rod from turning, which suits jobs where the plate must stay square. The trailing S in the SKU shows this model comes WITH a magnet for switch detection. AirTAC part number MK20X10S is listed and orderable; ask us to confirm dimensions or sizing from the datasheet 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.
Choose the 20mm bore for the thrust you need: at 0.5 MPa this double acting MK cylinder gives about 157.1 N on the push side and 131.9 N on the pull side. The MK series prevents rod rotation, while the MD series allows it, so pick MK where a plate or fixture must stay aligned. Acting type here is double acting with a 10mm stroke; double acting bores of 20mm go up to 60mm stroke, but the short cover means an over-long stroke is not advisable for a compact body. The trailing S means this SKU includes a magnet, and the thread is PT; a G-thread version is available if you prefer. Allowable side load depends on the application, so confirm it with us from the datasheet.
The 20mm bore gives about 157.1 N of push at 0.5 MPa to hold small parts in a fixture, and the no-rotating rod keeps the clamp pad facing the workpiece exactly as set.
Mount the square body from any of 6 directions inside a drill or weld jig, and the fixed rod stops the positioning plate from twisting out of square.
Side-by-side mounting lets banks of MK cylinders act as pop-up gates and stoppers on fixture rails, with the bumper cushioning each short 10mm move.
MK = no-rotating double acting, 20mm bore, 10mm stroke, and the trailing S means the magnet is included. A plate, fixed rod and brass bushing stop the rod from turning; an MD cylinder of the same bore is the standard type where rotation is allowed.
The square body can be fixed from 6 directions (front, back, left, right, top, bottom) and cylinders mount side by side to save space. Overall dimensions depend on the stroke and allowable side load depends on the application, so confirm both from the datasheet before designing the fixture.
