Airtac MDJ Adjustable Cylinder MDJ25X15-10S
The AirTAC Airtac MDJ Adjustable Cylinder MDJ25X15-10S is a genuine MD multi-mount cylinder (adjustable stroke), 25 mm bore. Its compact square body fixes from six directions and mounts side by side to save space. It delivers about 245.4 N of push force at 0.5 MPa. A bumper cushions the impact.

About the Airtac MDJ Adjustable Cylinder MDJ25X15-10S
The MDJ25X15-10S is an adjustable-stroke multi-mount cylinder from AirTAC's MD family: a compact square-body cylinder that can be fixed from 6 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. With a 25 mm bore, a 15 mm base stroke and a 10 mm adjustable range, it handles short clamping and positioning moves where the end of stroke is tuned on the machine; it is double acting, delivers about 245.4 N of theoretical push force at 0.5 MPa, and is cushioned by a bumper.
This is a genuine AirTAC part. The MD family is the standard multi-mount series (rod rotation is allowed; the MK family prevents rotation). The trailing S means this unit comes WITH a magnet for position-sensing switches. Operating pressure is 0.15-1.0 MPa (22-145 psi) and the medium is air filtered to 40 um. We can 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
Choose the 25 mm bore when you need about 245.4 N of push force at 0.5 MPa on the push side. MD means a standard multi-mount cylinder where rod rotation is allowed; pick MK if the rod must not rotate. The MDJ adjustable-stroke variant is double acting and adds a 10 mm adjustable range on top of the 15 mm base stroke for on-machine stroke setting.
Keep the base stroke within the bore's stroke table (25 mm bore: up to 60 mm); a 15 mm stroke keeps the body compact, and an over-long stroke should be avoided. The trailing S means this SKU carries the magnet for switch sensing - order the version without S if you do not need it. Thread is PT as standard, with G-thread available via the G suffix. Side-load limits and exact dimensions depend on the stroke - confirm from the datasheet or ask us.
Applications
Small-parts clamp with end-position sensing
Clamp small components in a compact assembly fixture and use the magnet and switch slots to confirm the clamp is fully closed before the next station starts.
Gate/stopper on a sorting conveyor
Raise and lower a short stopper gate to divert cartons or bins, setting the exact gate height with the 10 mm adjustable range and verifying position via the magnet.
Lift-and-locate pin in a welding jig
Raise a locating pin to seat a panel in a weld fixture, with several cylinders fixed from 6 directions around the jig to keep the tooling compact.
FAQ
How much force does the 25 mm bore produce and how far can the stroke be adjusted?
At 0.5 MPa this double-acting 25 mm bore gives about 245.4 N of theoretical push force. The MDJ25X15-10S has a 15 mm base stroke with a 10 mm adjustable range on top, so the effective stroke can be set within that window on the machine.
Are there stroke limits I should watch with this cylinder?
Yes. The cover is designed for short strokes, so avoid specifying an over-long stroke beyond the bore's table (25 mm bore: up to 60 mm). A 15 mm base stroke keeps the body compact. Exact dimensions and side-load limits come from the datasheet - ask us to confirm them.
