Airtac MTK Multi-position Locking Cylinder MTK32X20
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK32X20 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.

About the Airtac MTK Multi-position Locking Cylinder MTK32X20
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 MTK32X20 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, a simple choice for 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 SKU carries no S suffix, so this model is without a magnet. 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.
How to choose
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 keeps the rod from rotating; 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 no magnet and a PT thread; a G thread is available. Ask us about side-load limits.
Applications
Conveyor gate stopper
Mounted through the top or side of a conveyor frame, the no-rotating rod drops a square-faced stopper into the product flow; air retracts it for the 20 mm pass-through move.
Small-parts clamping
Bolted side by side on a fixture plate, several MTK cylinders can clamp small housings in line, with the fixed rod keeping clamp pads from twisting on the part.
Indexing pin fixture
The spring-extended rod acts as a positioning pin in a rotary index table; applying air pulls the pin clear for each 20 mm index step.
FAQ
What does the MTK code in MTK32X20 mean?
MK is AirTAC's no-rotating multi-mount family, where a fixed rod and plate stop the piston rod turning, and the leading M marks the single-acting pull type: air retracts the rod and the spring returns it. So MTK32X20 is a 32 mm bore, 20 mm stroke, single-acting pull cylinder without a magnet (no S suffix) and a PT thread.
Can I fix this cylinder from any side of the machine?
Yes. The square body can be fixed from six directions - front, back, left, right, top and bottom - and units mount side by side to save space, with magnetic-switch slots around the body. Note the short cover: keep the stroke well inside the single-acting table, and confirm side-load limits and exact dimensions from the datasheet.
