Airtac MK Series Multi-position Locking Cylinder MK32X70
The AirTAC Airtac MK Series Multi-position Locking Cylinder MK32X70 is a genuine MK multi-mount cylinder (double acting), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 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 MK32X70
The AirTAC MK32X70 is a 32 mm bore, 70 mm stroke, double acting no-rotating multi-mount cylinder. Its square body fixes from 6 directions - front, back, left, right, top and bottom - and cylinders mount side by side on the same pitch to save space. At 0.5 MPa this bore delivers about 402.1 N theoretical push force with cushioning by a bumper, running 30-500 mm/s on air filtered to 40 um.
This is a genuine AirTAC part. The MK family is the no-rotating version of the MD series: a fixed rod and plate stop the piston rod from turning, unlike a standard MD where rotation is allowed. This SKU is ordered without a magnet. Note that the standard bore 32 double-acting stroke table tops out at 60 mm, so please confirm the 70 mm stroke's availability and dimensions with us from the datasheet before ordering.

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 the bore for thrust: the 32 mm bore is the largest in the range, about 402.1 N push and 345.6 N pull at 0.5 MPa. MK is the no-rotating family; MD fits where rod rotation is acceptable. Acting is double acting here, with single-push MSK, single-pull MTK, double-rod MKD and adjustable-stroke MKJ variants available. This code decodes to 70 mm of stroke, beyond the standard 60 mm maximum shown for bore 32 double acting, so confirm the exact length with us before design freeze. Thread is PT (G available); no magnet is fitted. Keep strokes within the bore's table on these short covers and send side-load questions to us.
Applications
Wide-carton stopper
The longer decoded stroke suits a stopper plate that must clear a wider conveyor lane, with the non-rotating rod keeping the plate square to the flow.
Parts-lift ejector
Mounted under a chute and fixed through any of the 6 body faces, the cylinder lifts and lowers a small ejector blade, the bumper softening each retract.
Slide positioning
The fixed rod holds a small slide's orientation through repeated index moves, with cylinders mounted side by side where panel space is tight.
FAQ
The MK32X70 shows a 70 mm stroke - is that a standard length for a 32 mm bore?
The published stroke table for double acting bore 32 runs up to 60 mm, so a 70 mm stroke should be confirmed before you build it into a design. Contact us and we will check current availability and dimensions from the datasheet.
What stops the rod from rotating on this cylinder?
The MK family adds a no-rotating plate, brass bushing and fixed rod to the multi-mount body, so the piston rod cannot turn under load. The trade-off is that an MD should be used instead where the application does not need the orientation held.
