Airtac MTK Multi-position Locking Cylinder MTK20X20S
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK20X20S 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 MTK20X20S
The MTK20X20S is a genuine AirTAC compact multi-mount cylinder with a 20 mm bore and 20 mm stroke. Its square body fixes from six directions - front, back, left, right, top and bottom - so several units can sit 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 includes a magnet for position sensing. Typical materials are an aluminium-alloy body, covers and piston, stainless or S45C rod, NBR seals, a TPU bumper and a sintered NdFeB magnet; 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. At 20 mm, this stroke sits at the maximum for single-acting cylinders in this family, and the short covers mean an over-long stroke is best avoided - match the stroke to the job. The trailing S means this SKU includes a magnet; drop it for an unmagnetized unit. Port thread is PT as shown, with G available.
Applications
Spring-extend stopper on a conveyor
A spring-extend, air-retract pin holds small parts or totes at a gate on a conveyor line. Air pulls the pin down to release flow, and if air is lost the stopper stays up - mounted top-down on the frame with no rod rotation.
Reject gate actuator
Mounted on the side of a narrow conveyor, the pull-type rod retracts a swing or diverter gate to kick defective parts off the line, its non-rotating rod keeping the gate blade square to the product flow.
Lift-and-present pin in a test jig
In a compact test or assembly jig, the cylinder spring-extends a locating pin that lifts a workpiece into position; side-by-side mounting puts several pins in tight pitch along the fixture edge.
FAQ
What does MTK20X20S mean, and why choose a pull type?
MTK is AirTAC's no-rotating, single-acting pull-type multi-mount cylinder: 20 mm bore, 20 mm stroke, with a magnet (the 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 - useful for fail-safe stoppers and pins. If you need air to push the rod out instead, choose the MSK push type.
Can I mount this cylinder in any orientation?
Yes. The multi-mount square body fixes from six directions - front, back, left, right, top and bottom - and units mount side by side to save space. Note the short covers: keep the stroke matched to the task rather than over-long. Allowable side load and exact dimensions for this bore and stroke come from the datasheet; ask us and we will confirm them.
