Airtac MDJ Adjustable Cylinder MDJ32X45-20S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ32X45-20S is a genuine MD multi-mount cylinder (adjustable stroke), 32 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 402.1 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ32X45-20S
The MDJ32X45-20S is an AirTAC multi-mount cylinder with a compact square body you can fix from six directions: front, back, left, right, top and bottom. Units mount side by side so banks of cylinders fit into minimal panel space. This model is double acting with a 32 mm bore and a 45 mm stroke, the last 20 mm of which is adjustable, giving wide on-machine tuning of the end position. At 0.5 MPa it produces about 402.1 N of theoretical push force, and the cushion is a bumper.
This is a genuine AirTAC part from the MD family, the standard multi-mount series where rod rotation is allowed; choose the MK family when rotation must be prevented. The trailing S in the code means the magnet is included for magnetic-switch detection. 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
Pick the 32 mm bore for the highest thrust in this range, about 402.1 N push at 0.5 MPa. MDJ is the double-acting adjustable-stroke variant; this code gives a 45 mm stroke with a 20 mm adjustable range, within the 60 mm stroke maximum for bore 32. MD allows rod rotation, MK prevents it. The S suffix means the magnet is fitted, and the thread is PT on this model with G as the alternative. Respect the short-cover stroke caution and check side-load capacity against the datasheet with us.
Applications
Conveyor gate stopper
Bolted to the side frame of a small conveyor, the cylinder raises and lowers a stopper blade, with the 20 mm adjustable range setting exact stop height.
Test-rig jig clamping
In a compact test jig, side-by-side multi-mount bodies clamp fixtures sequentially, each 32 mm bore applying about 402.1 N of push at 0.5 MPa.
Vertical part lift
Fixed top or bottom under a small lifting plate, the double-acting cylinder raises parts about 45 mm while the magnet S version signals end-of-stroke via a magnetic switch.
FAQ
What is the difference between MDJ32X45-20S and the MK equivalent?
MDJ is the standard adjustable-stroke series, where some rod rotation is allowed; MKJ would be the no-rotating version with a fixed rod and plate that stops the rod turning. Both are 32 mm bore double-acting adjustable-stroke designs with the same 402.1 N push at 0.5 MPa.
How is the adjustable stroke set up on this model?
The code means a 45 mm stroke with a 20 mm adjustable range, so the effective stroke can be tuned within that range on the machine using the adjusting mechanism described in the datasheet. Exact adjustment details and dimensions for this stroke should be confirmed from the datasheet.
