Airtac MG Stainless Steel Mini Air Cylinder MG25X500S
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG25X500S is a genuine double acting JIS-standard round-body mini air cylinder with a Ø25mm bore and 500mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MG Stainless Steel Mini Air Cylinder MG25X500S
With a 500 mm stroke on a 25 mm bore, this MG25X500S covers long-travel pick-and-place moves while staying double acting: air drives the rod out and pulls it back, so there is no spring to rob force. Push force is 245.3 N and pull 206.1 N at 0.5 MPa, rising to 343.4 N and 288.5 N at 0.7 MPa. The JIS round body is riveted from a SUS304 stainless barrel onto the covers, and the hard-chrome plated 10 mm rod shrugs off washdown and damp shop air far better than a painted mini cylinder.
For sizing, treat about 147 N (roughly 15 kg of thrust) as the realistic working force at 0.5 MPa instead of the full rating; vertically that means the rod lifts about 12 kg with a 2:1 margin. The fitted magnet lets CMSG, DMSG or EMSG switches report end positions directly, and the fixed anti-impact bumper pads soften the direction change at each end of the long 500 mm travel.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X500S Is Used
Bottle rejection gate on a filling line
The 245.3 N push at 0.5 MPa sweeps off-spec bottles off a conveyor across the full 500 mm span, and the SUS304 barrel handles repeated washdown between batches.
Tray elevator with position feedback
Magnet and CMSG switches confirm top and bottom of the 500 mm lift; the rod raises about 12 kg of loaded trays vertically with a 2:1 margin.
Slide gate on a powder hopper
Long 500 mm travel opens a hopper outlet fully, the fixed bumper pad softens each stroke end, and the stainless body resists dusty, humid plant air.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X500S the Right Cylinder?
At 25 mm bore you sit mid-range: the 20 mm MG pushes only 157 N at 0.5 MPa, while stepping up to the 32 mm bore buys 402 N. If your load needs gentler stops at high speed or heavier mass, the cushioned MGC in 50 or 63 mm is the alternative. Note that a plain MG drifts when air is removed or the valve centres, so add an external rod lock or pilot check valve if the load must stay put. This SKU already carries the -S magnet, so sensor-ready mounting is covered. Mount with LB foot, FA flange, CB clevis or SDB pivot, and use I or Y rod knuckles on the M10x1.25 male thread. At 500 mm of stroke, keep side loads off the rod and guide the payload externally.
Quick checklist

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA / CB / SDB) & knuckle
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 MG Stainless Steel Mini Air Cylinder MG25X500S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa those rise to 343.4 N push and 288.5 N pull. The theoretical maximum is 50 kgf at 1.0 MPa. Bore is 25 mm, stroke 500 mm, rod 10 mm with M10x1.25 male thread, and every port is 1/8".
The fixed anti-impact pads at the stroke ends decelerate the piston to soften impact; they are not an adjustable air cushion and they do not lock or hold a load. The S means a magnet is built in, so CMSG, DMSG or EMSG switches can be clamped to the SUS304 barrel for end-position sensing.
