Airtac MTK Multi-position Locking Cylinder MTK6X5
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK6X5 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 MTK6X5
A multi-mount cylinder is a compact square-body actuator that fixes from six directions - front, back, left, right, top and bottom - and mounts side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. The MTK6X5 is the no-rotating single-acting pull type: air retracts the rod and an internal spring extends it, so the rod is presented whenever air is lost. The 6 mm bore and 5 mm stroke fit very short, light moves at 50-500 mm/s, and the cushion is a bumper.
This is a genuine AirTAC part. MD-family cylinders are the standard type whose rod may rotate, while MK-family models add a no-rotating plate, brass bushing and fixed rod that stop the piston rod turning. The code has no trailing S, so this SKU is supplied without the magnetic piston; the S versions add it. 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
Pick bore 6 for light-duty force; catalogue thrust is published for the push side of single-acting cylinders and the pull side is lower, so confirm pull figures from the datasheet. MD allows rod rotation, while this MK keeps the rod from turning with a no-rotating plate and fixed rod. MTK is single-acting pull type: air retracts the rod and the spring extends it. A 5 mm stroke sits well inside the single-acting table (up to 20 mm); keep strokes short for this bore and route side-load checks to us. No trailing S means no magnet on this SKU. The thread is PT as standard with G optional, and the port is M5x0.8.
Applications
Indexing pin on a rotary dial
The 5 mm spring-extended stroke drops a flat-tipped pin into dial detents; air retracts it as the dial indexes. The no-rotating plate keeps the tip aligned inside a tight housing.
Micro gate latch on a slide
Bolted to the side of a miniature slide gate, the spring-extended rod holds the gate closed at rest; air pulls the pin clear for opening, with no need to find room for a return spring.
Ejector in an assembly nest
The spring-extended pin pushes a finished micro part out of its nest, and air retraction resets it. Side-by-side mounting lets several ejectors share one compact manifold plate.
FAQ
Does MTK6X5 include a magnet?
No. The code has no trailing S, so this SKU is supplied without a magnetic piston. If you need proximity-switch detection, order the MTK6X5S version instead; the switch slots on the body are present either way.
Can I fit a long stroke to this small bore?
Single-acting models like this are listed up to 20 mm of stroke, and short covers caution against over-long strokes at small bores. This SKU is fixed at 5 mm. Confirm overall dimensions and side-load capability from the datasheet before designing the fixture.
