Airtac MTK Multi-position Locking Cylinder MTK6X20S
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK6X20S is a genuine MK multi-mount cylinder (single acting, pull type), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 2.2 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 MTK6X20S
Multi-mount cylinders are compact square-body actuators that fix from six directions - front, back, left, right, top and bottom - and mount side by side to save space, with magnetic-switch slots machined around the body. The MTK6X20S is the no-rotating single-acting pull type in this family: applying air retracts the rod and an internal spring extends it, so the rod stays out if air is lost. The 6 mm bore with a 20 mm stroke, the maximum listed for single-acting models, suits light, short-move work at 50-500 mm/s, and the cushion is a bumper.
This is a genuine AirTAC part. MD-family cylinders are the standard type with a rod free to rotate, while MK-family models like this one add a no-rotating plate, brass bushing and fixed rod that stop the piston rod turning. The trailing S in the code shows this SKU carries the magnetic piston; codes without an S are supplied without a magnet. It runs on air filtered to 40 um at 0.2-1.0 MPa (28-145 psi), and we confirm 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.
How to choose
Bore 6 is the smallest and lightest bore in the range. AirTAC's thrust tables list push-side figures for single-acting cylinders and the pull side is lower, so confirm this MTK's exact pull force from the datasheet before sizing. Choose MK over MD when rotation must be prevented: the no-rotating plate and fixed rod hold a flat tool or pad square to the work. The acting choice here is single-acting pull - air retracts, spring extends - useful for fail-safe out positions. Stroke 20 mm is the single-acting maximum; avoid over-long strokes on short covers, and send side-load questions to us. The trailing S selects the magnet option; the port is M5x0.8 with PT thread (G available).
Applications
Fail-safe conveyor stopper
Mounted under a light conveyor frame, the spring-extended rod lifts a stopper blade into the product path; applying air retracts it to release flow. The no-rotating plate keeps the blade face square to oncoming parts.
Spring-clamp small-parts nest
The rod stays out at rest to hold a small bracket in a drilling nest; a blast of air pulls it back for unloading. Side fixing from the fixture wall saves space in a crowded jig.
Lift pin for thin pallets
The 20 mm spring-extended stroke raises a locating pin through a thin pallet plate; air retracts it for transfer. Six-way fixing lets the body bolt beneath a cramped indexing table.
FAQ
What does the MTK6X20S model code mean?
MTK identifies a no-rotating, single-acting pull-type multi-mount cylinder: air retracts the rod and a spring extends it. The 6 is the 6 mm bore and 20 is the 20 mm stroke. The trailing S shows this SKU carries the magnet, and the missing thread letter means PT (G is available as an option).
Where can I mount this cylinder?
From any of six directions: front, back, left, right, top or bottom. The square body also lets you bolt cylinders side by side to save space, and magnetic-switch slots run around it. Dimensions for a given stroke come from the datasheet - ask us for a copy.
