About the Airtac MGC Stainless Steel Mini Cylinder MGC25X200S
The AirTAC MGC25X200S is a double acting, JIS-standard round-body mini cylinder with a 25 mm bore and 200 mm stroke, built with a variable air cushion at both stroke ends. Unlike the fixed bumper pad on the plain MG, this adjustable cushion lets you tune the needle valve to decelerate the piston smoothly near end of travel, so the cylinder tolerates higher piston speeds (up to 800 mm/s) and heavier moving loads without hammering the covers. At 0.5 MPa it delivers 245.3 N push and 206.1 N pull, rising to 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
Construction follows the JIS mini-cylinder footprint: an SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated (20 um) carbon-steel rod with a two-way piston seal that also stores lubricant. The 10 mm rod carries a male M10x1.25 thread and air supply is via 1/8" ports. Because the S code is fitted, a magnet is built in and CMSG, DMSG or EMSG switches can be mounted for position sensing. Operating range is 0.15 to 1.0 MPa (22-145 psi) with air filtered to 40 um, and the temperature span is -20 to +70 C. Note that the cushion only decelerates the stroke end; it is not a lock or brake, so an external rod lock or pilot check valve is recommended for a held load.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC25X200S Is Used
High-speed conveyor stop and divert
The variable air cushion absorbs the momentum of fast-moving totes or cartons at end of stroke, letting the 25 mm bore cycle at high speed without cover impact, while the fitted magnet feeds position feedback to the PLC.
Packaging machine pusher arms
With 245.3 N push at 0.5 MPa (about 15 kg safe working load), this cylinder pushes product into cartons or onto infeeds, and the adjustable cushion prevents product shift when the pusher reaches its stop.
Small assembly press and clamping
At 0.7 MPa the bore delivers 343.4 N push, enough for light pressing, staking and clamp fixtures, and the cushioned stroke end protects delicate tooling from hard seating.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC25X200S the Right Cylinder?
Size the MGC25X200S by its real force output: 245.3 N push (about 25.0 kgf) at 0.5 MPa. A practical rule of thumb is to use roughly 0.6 of the push force for safe working load, which gives about 15 kg as a conservative vertical-lift figure for this bore. Within the MGC range, bore 25 sits one step above the 20 mm bore (157.0 N push at 0.5 MPa) and one step below the 32 mm bore (402.2 N), so if your load needs more than about 15 kg safe lift, step up to 32; if less, the 20 mm bore saves space. For 20 to 40 mm bores, the bumper-type MG is the no-cushion alternative if end-of-stroke deceleration is not required. The 200 mm stroke is well inside the 500 mm maximum standard stroke for this bore, so no made-to-order surcharge applies. Mounting options are FA flange or LB foot, with I and Y rod knuckles available, and the fitted magnet means CMSG, DMSG or EMSG switches can be added anywhere along the barrel. At longer strokes or higher speeds, guide the load externally to keep side loading off the 10 mm rod.

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 and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGC Stainless Steel Mini Cylinder MGC25X200S FAQ
At 0.5 MPa it produces 245.3 N push and 206.1 N pull; at 0.7 MPa, 343.4 N push and 288.5 N pull. The theoretical maximum is 50 kgf at 1.0 MPa. Applying the standard 0.6 safety factor to the 0.5 MPa push force gives a safe vertical-lift figure of about 15 kg.
The cushion at both stroke ends is adjustable: a needle valve meters exhaust air to decelerate the piston smoothly before it reaches the cover, which suits higher speeds and heavier moving loads. It is a deceleration feature only, not a lock or brake, so the MGC25X200S will not hold position on air loss; use an external rod lock or pilot check valve for a held load.
