Airtac MSK Multi-position Locking Cylinder MSK6X20S
The AirTAC Airtac MSK Multi-position Locking Cylinder MSK6X20S is a genuine MK multi-mount cylinder (single acting, push type), 6 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 5.7 N of push 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 MSK Multi-position Locking Cylinder MSK6X20S
The AirTAC MSK series multi-mount cylinder is a compact square-body actuator that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side to save space. This MSK6X20S is a single-acting, push-type cylinder with a 6 mm bore and 20 mm stroke, the top of the standard stroke range for single-acting versions in this bore. At 0.5 MPa it delivers a theoretical push force of 5.7 N, operating at 0.2-1.0 MPa (28-145 psi) and 50-500 mm/s on air filtered to 40 um, with a bumper as the cushion. Magnetic-switch slots are machined around the body.
This is a genuine AirTAC part. The MK family is the no-rotating variant: a fixed rod and plate stop the piston rod from turning, so attached tooling stays aligned, unlike the standard MD family where rotation is allowed. The trailing S in MSK6X20S shows this SKU carries the magnet; SKUs without the S are supplied without one. 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
Choose the 6 mm bore when the job needs light force only: the theoretical push is 5.7 N at 0.5 MPa on this single-acting push type, which runs at 0.2-1.0 MPa (28-145 psi) and 50-500 mm/s. Pick MK over MD when the rod must not rotate; MD is the standard variant where rod rotation is acceptable. Single-acting strokes run up to 20 mm, so this model sits at the maximum - keep the stroke as short as the job allows, since the short cover cautions against over-long strokes. The trailing S orders the magnet version, ports are M5x0.8, and the thread is PT as shown, with G available as an option. Side-load figures and exact dimensions come from the datasheet - confirm with us.
Applications
Small-parts clamp
A single-acting push cylinder extends to hold a small component against a fixture during an assembly step, its no-rotating rod keeping the clamp pad square to the part.
Gate and stopper duty
Mounted side by side along a light assembly line, the compact body blocks or releases small items at a divert or stop point without taking up machine space.
Jig positioning
Fixed from the top or side of a jig, the cylinder pushes a lightweight workpiece into a reference position before fastening, with the rod held from turning.
FAQ
What does the S at the end of MSK6X20S mean?
The trailing S means this SKU includes the magnet, which lets magnetic switches detect piston position in the slots around the body. The same cylinder ordered as MSK6X20 without the S is supplied without a magnet. Magnet is an option on the MD/MK range, never a default.
Can I mount this cylinder from any face of the body?
Yes. The multi-mount design can be fixed from six directions: front, back, left, right, top and bottom. Units can also sit side by side to save space. For allowable side load and exact dimensions for this stroke, confirm from the datasheet or ask us.
