Airtac MTK Multi-position Locking Cylinder MTK20X5
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK20X5 is a genuine MK multi-mount cylinder (single acting, pull type), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 92.3 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 MTK20X5
The MTK20X5 is a genuine AirTAC compact multi-mount cylinder with a 20 mm bore and a very short 5 mm stroke. Its square body fixes from six directions - front, back, left, right, top and bottom - so units can be mounted side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. This is a single-acting, pull-type cylinder: compressed air does the work in one direction and a spring returns the piston, running at 50-500 mm/s with a bumper as the cushion. It operates on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to 70 C (up to 150 C only with the optional high-temperature seal material).
This belongs to AirTAC's MK family, so a no-rotating plate, brass bushing and fixed rod stop the piston rod from turning - the rod keeps its orientation without an external anti-rotation guide. As the SKU shows, this model is supplied without a magnet. Typical materials are an aluminium-alloy body, covers and piston, stainless or S45C rod, NBR seals and a TPU bumper; bore-specific detail is in the datasheet, which we will confirm for you on request along with dimensions and sizing.

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 20 mm bore when you need a compact no-rotating pull cylinder; the exact pull-side thrust for this single-acting model should be confirmed from the datasheet. MTK is the right pick when the rod must not rotate; if rotation is acceptable and double-acting force in both directions is needed, an MD multi-mount cylinder is the alternative. The 5 mm stroke suits short-travel jobs such as indexing pins and clamps, and the short covers reward keeping the stroke brief rather than stretching it. This SKU has no magnet; add the trailing S if you need position sensing. Port thread is PT as shown, with G available.
Applications
Short-stroke clamp in a machining fixture
A 5 mm pull stroke is ideal for a spring-extend clamp pin that secures a machined part in a fixture; air retracts the non-rotating rod to release the part, and the body fixes top-down on the fixture plate.
Product stopper on a tight-pitch line
Mounted beside a conveyor with parts in close pitch, the spring-extend rod lifts a stopper blade to hold small products; air pulls it down to release flow, and the non-rotating rod keeps the blade square.
Eject pin for small formed parts
In a small forming or molding station, the cylinder spring-extends an eject pin that pushes a finished part clear of the die; the compact body mounts side by side with other cylinders in the tooling.
FAQ
What does MTK20X5 decode to, and does it include a magnet?
MTK is AirTAC's no-rotating, single-acting pull-type multi-mount cylinder: 20 mm bore, 5 mm stroke, no magnet (there is no trailing S) and PT port thread. In a pull type, air pressure retracts the rod and the spring extends it, so the default position is out. If you need position sensing, choose the same cylinder with the S suffix; if you need air to push the rod out instead, choose the MSK push type.
Why is a short cover important with a 5 mm stroke?
The multi-mount body fixes from six directions and mounts side by side to save space, and its short covers suit brief strokes - stretching a cylinder beyond the travel the job needs wastes space and can destabilize the tooling. Keep the 5 mm stroke matched to short-travel work; allowable side load and exact dimensions for this bore and stroke come from the datasheet, and we will confirm them on request.
