About the Airtac MGD Double Rod Mini Cylinder MGD25X500S
The AirTAC MGD25X500S is a double acting, double rod JIS round-body mini cylinder with a 25 mm bore and a 500 mm stroke. A 10 mm rod exits both the front and back covers with the same M10x1.25 male thread at each end, so the two rod ends move together and the output force is equal in both directions: about 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa, with a theoretical maximum of 42 kgf at 1.0 MPa. Because both sides of the piston see the rod-side area, there is no separate push and pull figure, and the through-rod resists rotation and side load while keeping stroke-end position repeatable. The 500 mm stroke exceeds the 300 mm maximum standard stroke for this bore, so it is supplied as a made-to-order item.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with hard-chrome plated carbon-steel rods, riveted covers and a two-way lubricant-storing piston seal, suited to damp and washdown environments. A fixed anti-impact bumper pad softens the stroke ends, though it is not an adjustable cushion and does not hold a load. The fitted magnet (the S in the code) allows CMSG, DMSG or EMSG switches to be mounted on either rod end. Air supply is filtered to 40 um, operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, temperature range is -20 to +70 C, and speed is 30-800 mm/s. Ports are 1/8".

Where the Airtac MGD Double Rod Mini Cylinder MGD25X500S Is Used
Anti-rotation linear slide
The through-rod on the MGD25X500S resists rotation, keeping a 25 mm bore slide square over its 500 mm travel without external guides for light, symmetric loads.
Twin-load push station
With about 206.1 N available at each rod end at 0.5 MPa, one cylinder can drive two small clamp or eject pads simultaneously with identical force both directions.
Rear-mounted switch flag
The back rod end carries a CMSG/DMSG/EMSG switch flag or mechanical stop, giving stroke-end confirmation on this magnet-fitted, made-to-order 500 mm stroke unit.
Is the Airtac MGD Double Rod Mini Cylinder MGD25X500S the Right Cylinder?
At 25 mm bore this is the second-smallest MGD, delivering 206.1 N each way at 0.5 MPa. A practical working load is roughly 0.6 of that, about 123 N, and for a vertical lift that is around 12 kg halved for safety margin. Step up to the 32 mm bore (345.6 N) if you need more force, or down to 20 mm (131.9 N) for lighter duty; for bores of 50 or 63 mm, or if you need an adjustable cushion, move to the MGCD series, and for a single-rod cylinder use the MG. Choose this double-rod model when you need anti-rotation guidance, equal force in both directions, a rear rod end for a switch flag or a second load, or two synchronized outputs from one cylinder. Mounting is FA flange or LB foot, with I and Y rod knuckles available; there is no SDB or CB pivot option on the double-rod design. The -S magnet supports CMSG/DMSG/EMSG position sensing. Note that the 500 mm stroke is non-standard for this bore and is made to order, and on a long stroke keep side load on the rod low and support the workpiece; the cylinder does not hold position on air loss, so add an external rod lock or pilot check valve for a held load.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGD Double Rod Mini Cylinder MGD25X500S FAQ
Because the rod occupies both sides of the 25 mm piston, force is equal in both directions: 206.1 N at 0.5 MPa and 288.5 N at 0.7 MPa, with a theoretical maximum of 42 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), air must be filtered to 40 um, temperature range is -20 to +70 C, speed is 30-800 mm/s, and the port is 1/8". The fixed bumper pad softens the stroke ends but does not hold a load.
The MGD25X500S has a 10 mm rod exiting both covers with M10x1.25 threads at each end, so force is identical extending and retracting, the rod resists rotation and side load, and the rear end can carry a flag or drive a second load. The single-rod MG has a larger extend force but unequal retract force and no rear rod. The fitted S magnet allows CMSG, DMSG or EMSG switches. This 500 mm stroke exceeds the 300 mm standard maximum for bore 25, so it is made to order.
