The AirTAC Airtac MKD Multi-position Clamping Cylinder MKD20X10S is a genuine MK multi-mount cylinder (double rod), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 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.
The MKD20X10S is a genuine AirTAC double-rod multi-mount cylinder with a 20 mm bore and 10 mm stroke. Its compact square body fixes from 6 directions - front, back, left, right, top and bottom - and cylinders mount side by side to save space, with magnetic-switch slots around the body. The double-rod design carries a rod on both ends, and the no-rotating plate stops the rod from turning, so a 10 mm stroke suits short-throw, orientation-critical work. At 0.5 MPa the 20 mm bore delivers a theoretical push thrust of 157.1 N (131.9 N on the pull side), cushioning is a bumper, and this SKU carries a magnet for magnetic-switch position sensing. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), from -20 to 70 C.
This is a genuine AirTAC part from the MK family - a no-rotating cylinder where a fixed rod, plate and brass bushing prevent rod rotation, unlike the standard MD family where rotation is allowed. The trailing S in the model code means this unit is fitted with a magnet; the S is optional, not a standard fitting on every model. Typical materials include an aluminium-alloy body, a stainless or S45C rod and NBR seals; we confirm exact 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.
Choose the bore for thrust: this 20 mm bore gives 157.1 N theoretical push at 0.5 MPa (131.9 N pull side). MK is the no-rotating choice when the rod must not turn; standard MD suits applications where rotation is acceptable. This is a double-rod, double acting unit that works from both ends. The 10 mm stroke is well inside the 60 mm maximum for bore 20, but the short cover cautions against over-long strokes - verify the practical range on the datasheet. The S suffix means this SKU includes a magnet for switch sensing; drop the S if you do not need it. Ports are M5x0.8 with PT thread (G available). Side-load figures come from the datasheet - contact us for help.
The no-rotating plate keeps gripper tooling square during the 10 mm stroke, and the magnet signals end positions to the PLC so the pick point is repeatable every cycle.
Rod on both ends clamps or ejects from either side of the fixture, with 157.1 N push at 0.5 MPa and magnet sensing to confirm the part is clamped before machining.
On pallet or gate applications, the fixed rod orientation stops parts square, and the magnet output verifies the stopper is fully extended before the next station fires.
The trailing S means this cylinder is fitted with a magnet, so magnetic reed switches can be seated in the slots around the square body to detect end positions. Magnet is an option, not a given - the same cylinder without the S (MKD20X10) has no magnet.
A fixed rod, no-rotating plate and brass bushing stop the rod from turning, so attached tooling keeps its orientation - ideal for clamps, stoppers and pick-and-place tooling. The compact square body also fixes from 6 directions, and exact dimensions and side-load limits should be confirmed from the datasheet for your installation.
