Airtac MKJ Adjustable Cylinder MKJ16X15-20
The AirTAC Airtac MKJ Adjustable Cylinder MKJ16X15-20 is a genuine MK multi-mount cylinder (adjustable stroke), 16 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 100.5 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 MKJ Adjustable Cylinder MKJ16X15-20
The MKJ16X15-20 is an adjustable-stroke, no-rotating multi-mount cylinder from AirTAC. Its compact square body fixes from 6 directions - front, back, left, right, top and bottom - so cylinders can sit side by side and save space on the machine. With a 16 mm bore, 15 mm basic stroke and an added 20 mm adjustable range, it provides theoretical double-acting push thrust of 100.5 N at 0.5 MPa, cushioned by a bumper. Magnetic-switch slots run around the body.
This is a genuine AirTAC part from the MK family, which prevents piston rod rotation with a fixed rod and plate; the MD family is the standard type that allows rotation. This model code carries no S, so it is supplied without a magnet. Typical construction is aluminium alloy body, stainless or S45C rod and NBR seals - we confirm exact dimensions and bore detail 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 16 delivers 100.5 N theoretical push thrust at 0.5 MPa and 86.4 N on the pull side; move to bore 20 or 25 for heavier clamping. Pick MK when rod rotation must be prevented, MD when it does not matter. Acting options span double acting, single-acting push (MSK), single-acting pull (MTK), double rod (MKD) and adjustable-stroke (MKJ). Double-acting bore 16 strokes go up to 50 mm, and this unit adds a 20 mm adjustable range over its 15 mm basic stroke. No S suffix means no magnet; order thread as PT (blank) or G. Short strokes suit the compact covers best, and side-load capability should be confirmed with us from the datasheet.
Applications
Gate stopper
Bolt the body to the side of a conveyor frame and extend the rod as a stopper gate for parts; the no-rotating plate faces the product squarely and the bumper softens each arrival.
Small-parts clamp
Fix the cylinder from the top face of a tight fixture to hold a small component during a press or screwdriving step, tuning the 15-35 mm stroke range to the part height.
Jig positioning
Set the adjustable stroke to register workpieces against a jig datum on every cycle; the fixed rod and plate keep the contact face from twisting out of alignment.
FAQ
How much force does the MKJ16X15-20 produce?
At 0.5 MPa the 16 mm double-acting bore gives 100.5 N of theoretical push thrust, with 86.4 N available on the pull side. Operating pressure spans 0.15-1.0 MPa (22-145 psi) for this bore, and thrust scales with your supply pressure within that range.
Is there a limit on the stroke length?
Yes - the multi-mount design uses short covers, so keep strokes within the bore's table (bore 16 runs up to 50 mm double acting) rather than specifying an over-long stroke. For this adjustable model you get a 15 mm basic stroke plus a 20 mm adjustable range, with exact dimensions listed in the datasheet.
