The AirTAC Airtac MDJ Adjustable Cylinder MDJ32X70-30S 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.
The AirTAC multi-mount is a compact square-body cylinder that can be fixed from six directions - front, back, left, right, top and bottom - and mounted side by side to save space, with magnetic-switch slots around the body and high guide precision without added lubricant. This MDJ32X70-30S is the adjustable-stroke, double-acting variant with a 32 mm bore and 70 mm stroke plus a 30 mm adjustable range, giving a theoretical push thrust of 402.1 N at 0.5 MPa for clamping, positioning and stopping in compact layouts. Cushioning is a bumper, and it runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), 30-500 mm/s, from -20 to 70 C.
This is a genuine AirTAC part from the standard MD family; the MK family is the no-rotating version, which uses a fixed rod and plate to stop the piston rod turning. The trailing S in the SKU means this model is supplied with a magnet, so it suits the magnetic-switch slots on the body. We can confirm overall 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.
Pick the bore for thrust: at 0.5 MPa this 32 mm bore gives a theoretical 402.1 N on the push side as a double-acting cylinder (the pull side is lower). MD is the standard family where rod rotation is allowed; choose MK if the rod must not turn. Acting options are double acting, single push (MSD/MSK), single pull (MTD/MTK), double rod (MDD/MKD) and adjustable stroke (MDJ/MKJ, which add a 10-30 mm adjustable range). This SKU is coded for a 70 mm stroke with a 30 mm adjustable range; the short covers mean very long strokes should be checked with us first. The trailing S adds the magnet; PT thread is standard and G is available. Side-load ratings and exact dimensions come from the datasheet - ask us.
Fix the square body from the top or side of an assembly station and use the 30 mm adjustable range to set stopper height per product variant, with the magnet feeding position signals to the controller.
Mount the 32 mm bore cylinder top-fixed in a compact lift module; the theoretical 402.1 N push thrust at 0.5 MPa suits raising small pallets or trays between two levels.
Use the adjustable stroke to control the pressing distance when seating bearings, plugs or labels into small parts, with the bumper cushioning the end of the stroke.
The MDJ code is the adjustable-stroke version: it is still a double-acting 32 mm bore cylinder with 402.1 N theoretical push thrust at 0.5 MPa, but the -30 adds a 30 mm adjustable range on top of the 70 mm stroke, so one cylinder can cover several stroke settings in a jig or stopper. The S means it comes with a magnet.
Yes. The multi-mount square body can be fixed from six directions - front, back, left, right, top and bottom - and cylinders mount side by side to save space. Exact dimensions depend on the stroke, and side-load limits are in the datasheet, so confirm both with us before finalising the mounting.
