Airtac MKJ Adjustable Cylinder MKJ10X25-10S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ10X25-10S is a genuine MK multi-mount cylinder (adjustable stroke), 10 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 39.3 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 MKJ Adjustable Cylinder MKJ10X25-10S
The MKJ10X25-10S is an AirTAC multi-mount cylinder: a compact square-body unit that fixes from 6 directions (front, back, left, right, top and bottom) and mounts side by side with identical units to save space. With a 10 mm bore, double acting operation and a 25 mm stroke adjustable over an additional 10 mm, it suits short, precise movements in tight fixtures. At 0.5 MPa it delivers a theoretical push force of about 39.3 N, and cushioning is provided by a bumper.
This is a genuine AirTAC part. MK is the no-rotating family: a fixed rod and plate stop the piston rod from turning, unlike the standard MD family where the rod can rotate. As the SKU shows, this model includes a magnet for position detection. We confirm overall dimensions and sizing help 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 10 mm bore when the job needs about 39.3 N push at 0.5 MPa; smaller bores give less force, larger bores more. MK gives you a non-rotating rod; pick the standard MD family if rod rotation is acceptable. This is a double acting, adjustable-stroke unit: the 25 mm stroke sits within the bore 10 table (up to 35 mm for double acting), and the -10 suffix adds a 10 mm adjustable range on top. Keep the stroke short - an over-long stroke on a compact body is best avoided. The S suffix means this SKU includes a magnet; drop it if you do not need position detection. Thread is PT as standard; G is available. Side-load limits and exact dimensions: confirm from the datasheet or ask us.
Applications
Jig positioning between stations
The magnet allows end-of-stroke detection, so the non-rotating rod can advance a part to a known position in a jig before the next operation starts.
Small-parts clamping
Side-by-side fixing lets several 10 mm bore cylinders clamp multiple points of a small workpiece from one compact fixture, each with a set stroke stop.
Gate and stopper actuation
Mounted top or bottom on a conveyor line, the cylinder raises and lowers a stopper or gate in a tight footprint, with the bumper cushioning each stop.
FAQ
What does the S at the end of MKJ10X25-10S mean?
The trailing S means this cylinder is supplied with a magnet, which allows position detection near the body. The magnet is optional on the MK family: the same model without the S (MKJ10X25-10) has no magnet. Sensor selection should be confirmed from the catalogue.
How does the no-rotating feature help my application?
A plate, brass bushing and fixed rod stop the piston rod from turning during extension and retraction. That keeps workpieces, gates or levers facing the same direction without an external anti-rotation guide. Allowable side-load figures and exact dimensions are given in the datasheet, which we can supply on request.
