Airtac MKJ Adjustable Cylinder MKJ10X15-20S
The AirTAC Airtac MKJ Adjustable Cylinder MKJ10X15-20S 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 MKJ10X15-20S
The MKJ10X15-20S is an AirTAC MKJ no-rotating multi-mount cylinder with a compact square body that fixes from 6 directions: front, back, left, right, top and bottom. Bodies mount side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. This double-acting model has a 10 mm bore and 15 mm stroke, plus a 20 mm adjustable-stroke range from the J suffix. At 0.5 MPa it delivers a theoretical push thrust of 39.3 N for light clamping, positioning and stopping work, with a bumper as the cushion.
This is a genuine AirTAC part. The MK family prevents rod rotation via a no-rotating plate, brass bushing and fixed rod, unlike the standard MD family. The trailing S means this SKU is supplied WITH a magnet, so magnetic switches can be sensed in the body slots. Operating pressure is 0.2-1.0 MPa (28-145 psi), the medium is air filtered to 40 um, proof pressure is 1.5 MPa (215 psi), temperature is -20 to 70 C (0 to 150 C only with the optional high-temperature seal material), and the thread is PT. 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
Select the 10 mm bore when roughly 39.3 N of theoretical push thrust at 0.5 MPa fits the job; other bores give more or less thrust. Choose MK over MD when rotation must be prevented, and the J version when you need a 10, 20 or 30 mm adjustable range added to the 15 mm stroke (here 20 mm). This is double acting. The S suffix means this SKU includes the magnet for switch sensing; omit S if you do not need it. Thread is PT, with G available. Respect the short body cover and avoid over-long strokes, and route side-load questions to us.
Applications
Sensor-monitored stopper
Stops cartons or parts on a line with a non-rotating plate, while the built-in magnet lets switches in the body slots confirm extend and retract.
Pick-and-place head
Carries small parts between stations in a compact pick-and-place module, with side-by-side mounting and a rod that holds its angular position.
Small-parts clamp
Clamps light components in a tight fixture, fixed from any of 6 body faces and end-stroke position tuned with the adjustable range.
FAQ
What does the S in MKJ10X15-20S mean?
The trailing S means this SKU is supplied WITH a magnet in the piston, so magnetic switches can be sensed in the slots around the body. The same model without the S has no magnet. Magnet is an option on MD/MK cylinders, not a fixed feature, so order the S version only when you need switching.
Why must the stroke stay within the bore's table?
The multi-mount body has a short cover, so over-long strokes reduce guidance quality and reliability. Keep the stroke within the listed range for the bore and use the MKJ adjustable range to fine-tune the end position. Confirm exact dimensions and side-load limits from the datasheet, which we can supply on request.
