The AirTAC Airtac MTK Multi-position Locking Cylinder MTK32X20S is a genuine MK multi-mount cylinder (single acting, pull type), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 242.1 N of pull force at 0.5 MPa. A bumper cushions the impact. As an MK unit a fixed rod stops the piston rod rotating.
A multi-mount cylinder is a compact square-body air cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side to save panel space. This MTK32X20S is the single-acting pull type on a 32 mm bore with a 20 mm stroke: compressed air retracts the rod and the internal spring extends it, suiting short retract-and-return duties. It runs on air filtered to 40 um at 0.2-1.0 MPa, tolerates -20 to 70 C, cushions with a bumper and reaches single-acting speeds of 50-500 mm/s.
This is a genuine AirTAC part from the MK family, where a fixed rod and no-rotating plate stop the piston rod from turning, keeping the rod end square to the workpiece. The S suffix means this model carries a magnet for magnetic-switch detection. We confirm exact dimensions, pull-side thrust 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.
Pick the bore for the force you need: the 32 mm pull-side thrust at 0.5 MPa is listed in the datasheet and is lower than the push side, so confirm the figure with us before sizing. MK prevents rod rotation; where rotation is acceptable, the standard MD family is the alternative. Acting choices run from double acting (MK) through single-acting push (MSK), single-acting pull (MTK), double rod (MKD) and adjustable stroke (MKJ). Single-acting strokes go up to 20 mm, and the short cover means an over-long stroke should be avoided. This SKU has the magnet (S) and a PT thread; a G thread is available. Ask us about side-load limits.
In a compact pick-and-place head, the spring-extended no-rotating rod presents a gripper square to small parts; air pulls it back over the 20 mm transfer move and the magnet signals position to the controller.
Fixed through the side rail of a packaging line, the rod holds back products between cycles; switching detection via the magnet lets the PLC confirm the stopper is retracted before release.
Mounted side by side on a machining jig, units clamp small brackets in a row, with the non-turning rod keeping clamp pads flat against the workpiece.
The trailing S means the piston carries a magnet, so magnetic switches seated in the slots around the body can detect rod position. The magnet is optional on this family: the same cylinder without the S suffix, MTK32X20, is supplied without a magnet. Both keep the PT thread and the 1/8 inch port on the 32 mm bore.
The MK family's fixed rod and no-rotating plate stop the piston rod turning, so a stopper blade or clamp pad stays square to the product instead of twisting under load. Combined with the square body that fixes from six directions and mounts side by side, it fits tightly packed stations. Confirm side-load limits from the datasheet before applying side forces.
