About the Airtac MDJ Adjustable Cylinder MDJ20X10-10
The MDJ20X10-10 is an AirTAC MDJ adjustable-stroke multi-mount cylinder with a 20 mm bore and a 10 mm base stroke, extendable by a 10 mm adjustable range. Its square compact body fixes from 6 directions (front, back, left, right, top and bottom) and can be mounted side by side to save space, with magnetic-switch slots around the body. As a double acting cylinder it works at 0.15-1.0 MPa (22-145 psi) and at 0.5 MPa delivers a theoretical push force of 157.1 N, with a bumper as the cushion. No magnet is fitted on this SKU.
This is a genuine AirTAC part. The MD family is the standard multi-mount cylinder, where the rod is free to rotate unless your fixture prevents it; the MK family is the separate no-rotating version. Thread on this model is PT. We confirm exact 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
Bore 20 on this double acting cylinder gives a theoretical push force of 157.1 N at 0.5 MPa, so check your load against that figure. Choose MD if rod rotation is acceptable and MK if it must be prevented; MDJ gives double acting operation with an adjustable stroke. The 10 mm base stroke sits well inside the bore 20 table (up to 60 mm), and the MDJ design adds a 10 mm adjustable range on top, useful for fine-tuning the end position. The short cover means an over-long stroke should be avoided for this compact body; keep the stroke within the datasheet table. This SKU has no magnet; choose the S suffix if you need magnetic-switch detection. Thread is PT by default, with G available on request. Side-load limits depend on the mounting, so confirm from the datasheet.
Applications
Small-parts clamping
The 10 mm base stroke with a 10 mm adjustable range lets you fine-tune the clamp position on a 20 mm bore cylinder, holding small parts with 157.1 N of push force at 0.5 MPa while the square body fixes from 6 directions in a tight fixture.
Jig positioning
Side-by-side mounting of these compact square bodies lets a jig fixture place several MDJ cylinders next to each other for positioning pins or stops, saving space on the mounting plate.
Pick-and-place Z-stroke
A short, adjustable downward stroke suits compact pick-and-place heads: the 6-way mounting lets the cylinder bolt top or bottom as the layout demands, and the adjustable range trims the grip height.
FAQ
What does the -10 at the end of MDJ20X10-10 mean?
It is the adjustable stroke. The MDJ variant is double acting with a 10 mm base stroke, and the -10 suffix adds a 10 mm adjustable range on top, so the effective stroke can be extended by up to 10 mm within the design limits.
How many ways can this cylinder be fixed, and how do I check its dimensions?
The multi-mount square body fixes from 6 directions: front, back, left, right, top and bottom, and cylinders can be mounted side by side to save space. Because overall dimensions depend on the stroke, confirm the exact figures for MDJ20X10-10 from the datasheet, and route any side-load question to us.
