Airtac MSK Multi-position Locking Cylinder MSK10X20S
The AirTAC Airtac MSK Multi-position Locking Cylinder MSK10X20S is a genuine MK multi-mount cylinder (single acting, push type), 10 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 15.8 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 MSK Multi-position Locking Cylinder MSK10X20S
The MSK10X20S is an AirTAC multi-mount cylinder, a compact square-body air cylinder with the no-rotating feature: a fixed rod and no-rotating plate stop the piston rod from turning. The body fixes from 6 directions (front, back, left, right, top, bottom) and mounts side by side to save space, with magnetic-switch slots around the body. This is the single acting, push type - air drives the rod out and an internal spring returns it - in a 10 mm bore with 20 mm stroke. At 0.5 MPa it delivers about 15.8 N of push, and the cushion is a bumper.
This is a genuine AirTAC part from the MK family (no-rotating); the MD family is the standard variant where the rod may rotate. This SKU includes the magnet (trailing S), so switch positions can be sensed from the body slots. Typical construction is an aluminium-alloy body, stainless or S45C rod, NBR seals and a TPU bumper. We confirm exact dimensions and 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.
How to choose
For light push duties, the 10 mm bore gives about 15.8 N of push at 0.5 MPa; a 16 or 20 mm bore delivers more. Choose MK over MD when the rod or attached plate must not rotate. This MSK code is single acting, push type (spring return); double acting (MK), single acting pull (MTK), double rod (MKD) and adjustable-stroke (MKJ) are the alternatives. The 20 mm stroke is at the top of the single-acting range of up to 20 mm - the short covers discourage over-long strokes, and side-load capability is best confirmed with us. This SKU carries the magnet (S), and the port thread is PT; a G thread is available.
Applications
Small-parts clamping
Spring return pushes a clamp pad onto a small part in a fixture, holding it while it is processed - the spring releases the part the moment air is removed.
Gate and stopper duty
Side-by-side mounting along a light conveyor lets the non-rotating rod push a stopper square into the flow to pause or divert small parts, with magnet sensing from the body slots.
Jig positioning
Fixed from 6 directions in a tight jig, the non-rotating rod indexes a workpiece into position without twisting any bracket on the rod end.
FAQ
What does the MSK and the S in MSK10X20S mean?
MSK is AirTAC's single acting, push type version of the MK no-rotating multi-mount cylinder: air pressure pushes the rod out and an internal spring returns it. The trailing S means this SKU comes with the magnet, so position switches can be sensed from the slots around the body. Operating pressure is 0.2-1.0 MPa (28-145 psi) with about 15.8 N of push at 0.5 MPa for this bore.
Why does the MK family not rotate, and why keep the stroke short?
The MK body adds a no-rotating plate, brass bushing and fixed rod, so the piston rod cannot turn - useful when the load must stay square. The 20 mm stroke here is the maximum for single-acting MSK cylinders; the compact covers mean over-long strokes are discouraged, and exact dimensions and side-load limits come from the datasheet.
