Airtac MKD Multi-position Clamping Cylinder MKD32X40S
The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD32X40S is a genuine MK multi-mount cylinder (double rod), 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 MKD Multi-position Clamping Cylinder MKD32X40S
The AirTAC MKD32X40S is a double-rod multi-mount cylinder with a 32 mm bore and 40 mm stroke, built with a magnet as the S in the code shows. The compact square body fixes from 6 directions - front, back, left, right, top and bottom - so units mount side by side to save space, and the magnetic-switch slots around the body take position-sensing switches. With rods on both ends, each side works on the annular piston area for a theoretical thrust of 345.6 N at 0.5 MPa, cushioning is a bumper, the medium is air filtered to 40 um, proof pressure is 1.5 MPa (215 psi), speed range is 30-500 mm/s, and no added lubricant is needed. It operates from -20 to 70 C, extended to 0-150 C only with the optional high-temperature seal material.
This is a genuine AirTAC part from the MK family, where a no-rotating plate, brass bushing and fixed rod stop the rod turning - the standard MD family allows rotation instead. Typical materials are aluminium alloy body, covers and piston, stainless or S45C rod and NBR seals; bore-specific details, overall dimensions and sizing should be confirmed from the datasheet, which we provide 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
The 32 mm bore gives an annular-side theoretical thrust of 345.6 N at 0.5 MPa over a 0.15-1.0 MPa (22-145 psi) operating range - choose a smaller bore only if that force is more than you need. MKD means a double rod on AirTAC's no-rotating platform: force from both ends with no rod twist. For a single-acting push or pull version choose MSK or MTK, or MKJ if you want an adjustable stroke with a 10/20/30 mm range. The 40 mm stroke is comfortably inside the 60 mm limit for double-acting 32 mm bores; the short cover design rewards keeping the stroke no longer than the application really needs, and side-load capacity should be checked against the datasheet with us. The trailing S means this cylinder carries a magnet for switch sensing; without the S there is none. Thread is PT as standard with G optional; ports are 1/8" on bore 32.
Applications
Indexing table latch
Mounted from the top or side of an indexing dial, the double rod advances and retracts a locking pin from either end while the fixed rod and no-rotating plate keep the pin square, and the magnet lets a switch confirm the locked position.
Vertical stopper in a lift station
Fixed through the frame top or bottom, the rod serves as a non-turning stop or lift post with the magnet signalling up and down positions to the PLC, all in a body short enough to sit beside adjacent cylinders.
Jig positioning pins
A row of MKD cylinders bolted side by side on a weld or assembly jig deploys non-rotating locating pins from both ends, the magnet on this model confirming pin-extended detection for interlocking.
FAQ
Why does the MKD32X40S show 345.6 N rather than a higher push figure?
MKD is a double-rod cylinder, so rods occupy both ends of the bore and each working side acts on the annular piston area. The validated theoretical thrust at 0.5 MPa for this 32 mm bore on that side is 345.6 N, used across the 0.15-1.0 MPa (22-145 psi) operating range.
What does the S at the end of the model code tell me?
The trailing S means this cylinder is built with a magnet, so magnetic switches can be seated in the slots around the body for end-position sensing; the same model without an S has no magnet. Mount it from any of 6 directions and place units side by side to save space.
