Airtac MKJ Adjustable Cylinder MKJ20X60-20
The AirTAC Airtac MKJ Adjustable Cylinder MKJ20X60-20 is a genuine MK multi-mount cylinder (adjustable stroke), 20 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 157.1 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 MKJ20X60-20
The MKJ20X60-20 is an adjustable-stroke, no-rotating multi-mount cylinder from AirTAC's MK family. Its square body fixes from six directions - front, back, left, right, top and bottom - and cylinders can be mounted side by side to save space, with switch slots around the body and high guide precision without added lubricant. At 20 mm bore on double-acting air it delivers a theoretical push of about 157.1 N at 0.5 MPa, suiting clamping and positioning of small parts, and the cushion is a bumper.
This is a genuine AirTAC part. MK (rather than MD) means rod rotation is stopped by a no-rotating plate, bushing and fixed rod; typical materials are an aluminium-alloy body, stainless or S45C rod and NBR seals - confirm bore-specific detail from the datasheet. With no trailing S, this SKU is supplied WITHOUT a magnet; switch detection can be planned separately if needed. Dimensions vary with stroke, so we confirm 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 20 mm bore when about 157 N of push at 0.5 MPa (131.9 N on the pull side) meets the load; go up a bore for more thrust. MKJ is adjustable stroke on a double-acting cylinder, and MK over MD means rotation is prevented. Stroke is 60 mm with a 20 mm adjustable range coded on top; the short cover cautions against pushing stroke length beyond the design, so validate with the datasheet through us. No S means no magnet on this SKU - add S if sensing is required. Thread is PT here (G available). Side-load limits come from the datasheet - ask us.
Applications
Fixture clamp with tuned stroke
The 20 mm adjustable range lets a fixture builder trim exactly how far the non-rotating pad travels to bear on the workpiece.
Chute divert gate
Fixed top or bottom, the rod swings a gate that cannot twist, routing small parts between two chutes on a compact panel of side-by-side cylinders.
Lab sampler actuator
Six-direction fixing lets the cylinder drop vertically into tight benchtop analyser frames, where the fixed rod keeps a probe aligned.
FAQ
Does MKJ20X60-20 include a magnet?
No. There is no trailing S in this model code, so the cylinder is supplied without a magnet; magnet versions carry an S at the end of the code. Everything else decodes the same: MK family no-rotating, adjustable-stroke, double acting, 20 mm bore, 60 mm stroke, 20 mm adjustable range, PT thread.
Where can this cylinder be fixed from?
The multi-mount square body fixes from six directions - front, back, left, right, top and bottom - and several units can be mounted side by side to save space. Exact dimensions for the 60 mm stroke and any allowable side-load figures come from the datasheet, which we confirm on request.
