Airtac MDJ Adjustable Cylinder MDJ32X40-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ32X40-10S 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 MDJ32X40-10S
The AirTAC MDJ32X40-10S is an adjustable-stroke, double acting multi-mount cylinder with a 32 mm bore, 40 mm base stroke and an extra 10 mm adjustable range, so you can fine-tune the effective stroke without changing cylinders. The compact square body fixes from 6 directions (front, back, left, right, top and bottom) and can be mounted side by side with neighbours to save space, with magnetic-switch slots around the body and high guide precision without added lubrication. Cushioning is a bumper. At 0.5 MPa this bore gives a theoretical push force of 402.1 N, suited to clamping, positioning and pushing jobs on compressed air filtered to 40 um, with an operating range of 0.15-1.0 MPa (22-145 psi) and a working temperature of -20 to 70 C.
This is a genuine AirTAC part. The MD family is the standard multi-mount series, where rod rotation is allowed; the MK family adds a no-rotating plate when rotation must be prevented. The trailing S in the SKU means this unit is supplied WITH a magnet, which pairs with the body's switch slots. We confirm overall dimensions and sizing for your stroke 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
Choose the 32 mm bore when you need the strongest thrust in the range: 402.1 N push (345.6 N pull) at 0.5 MPa, within a 0.15-1.0 MPa operating window. This MDJ variant is double acting, and the adjustable-stroke design adds a 10 mm tuning range on top of the 40 mm base stroke. If rod rotation must be prevented, step across to the MKJ no-rotating series instead of MDJ. Keep the base stroke within the bore 32 table (up to 60 mm); the short body cover cautions against over-long strokes, so ask us before pushing past the catalogue. Magnet (S suffix) and thread (PT default or G) are the other ordering choices; side-load capability is confirmed from the datasheet.
Applications
Small-parts clamping
Bolt the square body top or bottom into a fixture and use the 402.1 N push at 0.5 MPa to clamp small parts, with the 10 mm adjustable range setting exact clamp height.
Machine indexing stop
Mount cylinders side by side on a machine frame as a stopper or indexing pin, advancing and retracting with double acting air and landing on the bumper cushion.
Press-fit assist
Fix the body from the front or back of a compact assembly station and deliver short, tunable pressing strokes where a full-size cylinder will not fit.
FAQ
What does the 10 in MDJ32X40-10S mean?
MDJ is the adjustable-stroke version of the double acting MD multi-mount cylinder. 32 is the bore, 40 the base stroke in mm, and -10 adds a 10 mm adjustable range on top. The S suffix means the unit is supplied WITH a magnet for the body's switch slots.
Can I mount this cylinder on any face of the body?
Yes. As a multi-mount cylinder it fixes from 6 directions: front, back, left, right, top and bottom, and units can be mounted side by side to save space. For exact overall dimensions at your stroke, side-load limits and mounting details, confirm from the datasheet or ask us.
