Airtac MSK Multi-position Locking Cylinder MSK32X20S
The AirTAC Airtac MSK Multi-position Locking Cylinder MSK32X20S is a genuine MK multi-mount cylinder (single acting, push type), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 281.5 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 MSK32X20S
The MSK32X20S is a 32 mm bore, 20 mm stroke single-acting push-type cylinder from AirTAC's MK multi-mount series, built with a magnet. The compact square body fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side to save space, with magnetic-switch slots around the body. Air pressure pushes the rod out and a spring returns it, giving a theoretical push thrust of 281.5 N at 0.5 MPa, with cushioning by bumper. As an MK-series cylinder, the rod is prevented from rotating.
This is a genuine AirTAC part. The MK family is the no-rotating variant of the multi-mount range; the MD family is the standard type that allows rod rotation. The trailing S in this SKU shows the cylinder is supplied with a magnet for position detection. Dimensions and sizing for this bore and stroke are per the datasheet, and we will confirm them 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 32 mm bore when the job needs single-acting push force: the theoretical thrust is 281.5 N at 0.5 MPa. Within the multi-mount range, MK prevents rod rotation while MD allows it. This MSK model is single acting, push type: air extends the rod, a spring returns it. Single-acting strokes run up to 20 mm, so 20 mm sits at the top of the range; the covers are short, so do not over-specify stroke. This SKU carries the S suffix, meaning a magnet is fitted; non-magnetic versions are listed without the S. The port is 1/8" with PT thread; G thread is available. Side-load capacity is not quoted here - contact us and we will confirm from the datasheet.
Applications
Small-parts clamping
Air pushes the clamp jaw out to grip small parts and the spring retracts it between cycles. The no-rotating rod keeps the clamp pad square to the work, the magnet signals jaw position to the controller, and the 6-way body fixing suits cramped fixture layouts.
Jig positioning on assembly lines
The push rod extends a locating pin into a jig to set part position, then the spring withdraws it for unloading. With the magnet fitted, the controller confirms pin extension, and several cylinders mount side by side where multi-station jigs need compact actuation.
Conveyor gate and stopper
The rod pushes a stopper blade into the product path to hold parts at a station, with the spring retracting it to release flow. The non-rotating rod keeps the blade level across the belt, and end-of-stroke sensing via the magnet supports interlocked release.
FAQ
Does the S at the end of MSK32X20S mean anything?
Yes - the trailing S means this cylinder is supplied with a magnet, so reed or Hall-effect switches seated in the slots around the square body can detect rod position. The same cylinder without the S suffix, such as MSK32X20, is supplied without a magnet; the magnet is an option, not a standard feature.
Can this cylinder be mounted in any orientation?
The multi-mount body fixes from 6 directions - front, back, left, right, top and bottom - so it can be bolted on whichever face the machine layout offers, and units mount side by side to save space. Keep the stroke within the single-acting limit of 20 mm; the short covers mean an over-long stroke is best avoided. Exact dimensions and side-load figures are in the datasheet - ask us to confirm.
