Airtac MK Series Multi-position Locking Cylinder MK6X20S
The AirTAC Airtac MK Series Multi-position Locking Cylinder MK6X20S is a genuine MK multi-mount cylinder (double acting), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 14.1 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 MK Series Multi-position Locking Cylinder MK6X20S
The AirTAC MK6X20S is a compact square-body multi-mount cylinder with a 6 mm bore and 20 mm stroke. The body fixes from 6 directions (front, back, left, right, top and bottom) and cylinders mount side by side, saving space in dense panels and fixtures. As a double-acting no-rotating cylinder it keeps the rod from turning during extension and retraction; at 0.5 MPa it gives a theoretical push thrust of 14.1 N, with a bumper cushion. Magnetic-switch slots around the body make position sensing straightforward, and guide precision is high without added lubrication.
This is a genuine AirTAC part from the MK no-rotating family, which adds a no-rotating plate, brass bushing and fixed rod to the compact square body. The trailing S in the code means this SKU is supplied with a magnet for switch detection, and with PT thread as standard on M5x0.8 ports. 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
Bore 6 delivers 14.1 N theoretical push thrust at 0.5 MPa; move to a larger bore if the job needs more force. Pick MK instead of MD when rod rotation must be prevented - MD is the standard family. This is a double-acting version with a 20 mm stroke, well within the 35 mm stroke limit for bore 6.
The trailing S means the magnet is built in, so reed or Hall-effect switches can be clipped into the body slots; the plain MK6X20 without S has none. Thread is PT here, or choose the G variant. Keep strokes short to suit the compact cover, and route any side-load question to us for a datasheet answer.
Applications
Pick-and-place part ejection
Side-by-side mounted at the end of a small assembly station, the no-rotating rod pushes finished micro-parts off a nest, with magnet-equipped switch slots confirming extend and retract.
Small-parts clamping
Fixed from the top of a compact fixture, the 6 mm no-rotating rod clamps miniature components without twisting, holding the clamp face square to the part.
Indexing pin actuation
Mounted beneath an indexing dial, the cylinder raises a locating pin into each station, and the fixed rod keeps the pin tip oriented exactly.
FAQ
What does the S at the end of MK6X20S mean?
The trailing S means this cylinder is supplied with a magnet in the piston, so magnetic switches can be mounted in the slots around the body to signal position. A code without S, such as MK6X20, is supplied without a magnet. With no trailing G, the thread on this SKU is PT.
Why choose the MK no-rotating version for tight spaces?
The square body fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side to save space, while the fixed rod and no-rotating plate stop the rod from turning - useful for pins and pushers that must stay aligned. Confirm exact dimensions and side-load limits from the datasheet.
