Airtac MK Series Multi-position Locking Cylinder MK6X35
The AirTAC Airtac MK Series Multi-position Locking Cylinder MK6X35 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 MK6X35
The MK6X35 is a compact AirTAC multi-mount cylinder with a square body you can fix from 6 directions - front, back, left, right, top and bottom - so it can sit side by side with neighbors to save panel space. This 6 mm bore, 35 mm stroke, double acting no-rotating version holds 14.1 N of theoretical push thrust at 0.5 MPa, and a bumper cushions the stroke at each end. Operating range is 0.2-1.0 MPa on air filtered to 40 um, with speeds of 30-500 mm/s and a temperature window of -20 to 70 C.
This is a genuine AirTAC part from the MK family, where a no-rotating plate, bushing and fixed rod stop the piston rod from turning - useful when the load must stay aligned. The SKU shows no S suffix, so this unit is without a magnet. We confirm 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
Bore sets the force: at 6 mm you get 14.1 N theoretical push at 0.5 MPa (10.6 N on the pull side), so step up to 10, 16, 20, 25 or 32 mm if the job needs more. MK means the rod is prevented from rotating; choose MD if some rod rotation is acceptable. This is a double acting unit with a 35 mm stroke, and the 6 mm bore stroke table tops out at 35 mm, so check the datasheet if you are considering anything longer. The no S suffix means no magnet; add an S suffix model if you need position sensing. Port thread is PT by default; a G thread is available as a suffix option.
Applications
Small-parts clamping
Bolted from the side of a fixture, the no-rotating rod pushes straight into a 6 mm part to clamp it without twisting, and the square body fixes from any of 6 directions to fit the jig layout.
Rotary valve indexing
A fixed rod plate drives an indexed dial or selector plate that must land square every cycle, since the MK design stops the rod turning between the cylinder and the load.
Slide gate actuation
Mounted top or bottom on a small slide gate, the 35 mm stroke opens and closes a parts divert or metering gate, with units placed side by side where panel space is tight.
FAQ
What does the MK prefix tell me about this cylinder?
MK is the no-rotating version of the multi-mount family: a plate, bushing and fixed rod stop the piston rod from turning, so a plate or gate stays aligned. The MD prefix is the standard version where the rod may rotate. Both are double acting, and both use a bumper cushion.
How many ways can I mount this cylinder, and what about loads off the rod axis?
The square body fixes from 6 directions - front, back, left, right, top and bottom - and the magnetic-switch slots sit around the body, so units can be mounted side by side to save space. Side-load ratings and exact body dimensions are stroke specific, so confirm them from the datasheet.
