Airtac MSK Multi-position Locking Cylinder MSK6X20
The AirTAC Airtac MSK Multi-position Locking Cylinder MSK6X20 is a genuine MK multi-mount cylinder (single acting, push type), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 5.7 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 MSK6X20
The AirTAC MSK series is a compact multi-mount cylinder with a square body that can be fixed from six directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space. This MSK6X20 is the single-acting, push-type version: air pressure extends the rod, and on the 6 mm bore it gives a theoretical push force of 5.7 N at 0.5 MPa. It runs on air filtered to 40 um at 0.2-1.0 MPa, at 50-500 mm/s, with cushioning provided by a bumper.
This is a genuine AirTAC part. As an MK-family cylinder it is no-rotating: a fixed rod and plate stop the piston rod from turning, so anything you attach keeps its orientation. This SKU carries no S suffix, so it is supplied without a magnet - choose MSK6X20S if you need one. Full dimensions and sizing details can be confirmed 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
Choose bore 6 when the job needs a light push - about 5.7 N theoretical at 0.5 MPa on this single-acting bore. Pick MD if rod rotation is acceptable; pick this MK family when rotation must be prevented. MSK is the push type (MTK is the pull version, MK and MKD are double acting). Single-acting strokes run up to 20 mm, so this 20 mm stroke sits at the top of the table - the compact covers are not intended for over-long strokes, so check the fit before selecting. Operating range is 0.2-1.0 MPa (28-145 psi). The trailing S adds a magnet, and the port thread is PT as standard with G available. Side-load limits are not listed here - confirm them with us from the datasheet.
Applications
Small-parts clamping
A light 5.7 N push at 0.5 MPa clamps tiny components in assembly fixtures, and the no-rotating rod keeps the contact face from twisting out of position.
Pick-and-place ejection
Ejects or lifts tiny parts at a pick-and-place station over a 20 mm move; the side-by-side mounting keeps multi-cylinder stations compact.
Indexing stopper
Acts as a stopper or indexing pin on small rotary and linear indexing fixtures, with the no-rotating rod holding the pin face square to the part.
FAQ
How long can the stroke be on this cylinder?
On single-acting multi-mount cylinders such as the MSK6X20, strokes run up to 20 mm, so this model is at the maximum. The compact covers are not designed for over-long strokes, so do not stretch beyond the table. Adjustable-stroke versions (MKJ) are double-acting models and add a 10, 20 or 30 mm adjustable range on top of the base stroke.
What does no-rotating mean on the MSK6X20?
As an MK-family cylinder, it has a no-rotating plate and fixed rod that stop the piston rod from turning, so attached tooling keeps its orientation - useful for stopper pins, gates and light clamping where the face must stay square. Standard MD-family cylinders do not prevent rotation. Side-load limits and exact dimensions come from the datasheet - confirm with us.
