Airtac MTK Multi-position Locking Cylinder MTK6X5S
The AirTAC Airtac MTK Multi-position Locking Cylinder MTK6X5S 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 MTK6X5S
Multi-mount cylinders are compact square-body actuators that fix from six directions - front, back, left, right, top and bottom - and sit side by side to save space, with magnetic-switch slots machined around the body. The MTK6X5S is the no-rotating single-acting pull type: air retracts the rod and an internal spring extends it, keeping the tool presented on air loss. The 6 mm bore and 5 mm stroke suit very short, light moves at 50-500 mm/s, with a bumper as the cushion.
This is a genuine AirTAC part. MD-family cylinders are the standard type with a free-rotating rod, while MK-family models 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 includes the magnetic piston, useful for switch detection in the body's slots. 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 gives light force; catalogue thrust tables list push-side values for single-acting cylinders and the pull side is lower, so confirm the exact figure from the datasheet. Between the families, MD permits rod rotation while MK prevents it via a no-rotating plate, brass bushing and fixed rod. MTK is single-acting pull: air retracts, spring extends. The 5 mm stroke is well inside the single-acting range (up to 20 mm), cushioned by a bumper; keep strokes proportionate to the short covers and ask us about side load. The trailing S selects the magnetic piston, and the port is M5x0.8 with PT thread (G on request).
Applications
Position-checked spring gripper
The spring holds gripper pads out on a small pick head; air retracts them to release. The magnetic piston feeds a switch signal so the controller confirms pad position in a body too tight for an external sensor.
Signalled micro stopper
A spring-extended stopper blade halts small cartons on a light conveyor; air retracts it to release. The magnet plus the body's switch slots verify retraction before the next product is sent.
Tote stop in a compact sorter
Bolted top-down between sorter lanes, the spring-extended pin stops totes at a divert point; air retracts it for release, and the magnet confirms the stop is clear.
FAQ
How do I read the code MTK6X5S?
MTK means a no-rotating, single-acting pull-type multi-mount cylinder; 6 is the 6 mm bore and 5 is the 5 mm stroke. The trailing S means the magnetic piston is included, and the missing thread letter means PT as standard, with G available as an option.
Why choose the MK no-rotating type?
When a flat pad, flag or stopper must stay square to the work, the MK family's no-rotating plate, brass bushing and fixed rod stop the rod from turning. In a pull-type MTK the spring holds the rod out and air retracts it, so the tool stays presented if air is lost.
