Airtac MG Stainless Steel Mini Air Cylinder MG25X450
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG25X450 is a genuine double acting JIS-standard round-body mini air cylinder with a Ø25mm bore and 450mm 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 MG25X450
With a 450 mm stroke on a 25 mm bore, this MG delivers 245.3 N push and 206.1 N pull at 0.5 MPa (343.4 N / 288.5 N at 0.7 MPa) in a double acting design, so compressed air drives the rod both out and back. The JIS-standard round body pairs a SUS304 stainless barrel with a hard-chrome plated 10 mm rod, riveted covers sealing the tube without tie rods. A fixed anti-impact bumper pad at each end softens the direction change - it decelerates only and is not an adjustable air cushion.
For sizing, treat roughly 147 N (about 15 kg of thrust) as the practical working force at 0.5 MPa; halving the raw 25 kg vertical-lift equivalent gives a 2:1 margin, so plan on lifting about 12 kg vertically. The long 450 mm stroke suits sliding doors, ejectors and indexing slides, but keep side loads off the M10x1.25 rod. Note that this SKU carries no magnet: the optional S code is required before a CMSG, DMSG or EMSG switch can be fitted.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG25X450 Is Used
Bottling line gate actuator
The 450 mm stroke swings or pushes a conveyor gate across a 400 mm product lane, with the 245.3 N push at 0.5 MPa easily cycling a lightweight aluminium gate at 30-800 mm/s.
Indexing pusher on an assembly slide
A 15 kg-class working thrust (about 147 N) parts and indexes small housings along a fixture table, while the SUS304 barrel shrugs off cutting-fluid mist.
Lift-assist for small trays
With a 2:1 margin the cylinder lifts about 12 kg vertically, enough to raise loaded bakery or electronics trays between bench and conveyor levels.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG25X450 the Right Cylinder?
At 25 mm bore you sit mid-range: the 20 mm MG gives about 157 N push at 0.5 MPa, while stepping up to 32 mm raises that to about 402 N - choose the larger bore if your 450 mm stroke moves a heavier slide. Remember a plain MG does not hold position when air is lost; the piston drifts, so add an external rod lock or pilot check valve for held loads. Mount with LB foot, FA flange, CB clevis or SDB pivot (with CB), and order the -S magnet version if you need CMSG / DMSG / EMSG sensing. For very high speeds or heavy loads needing adjustable deceleration, the cushioned MGC is the related variant.

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 MG25X450 FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa that rises to 343.4 N push and 288.5 N pull. Theoretical maximum force at 1.0 MPa is 50 kgf. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-800 mm/s, and a 1/8" port on this 25 mm bore.
Not as supplied - this SKU has no magnet. Order the S-coded version (e.g. MG25X450S) to enable CMSG, DMSG or EMSG reed/hall switches on the 10 mm rod. Also note the fixed bumper pads only soften stroke-end impact; they do not lock or hold a load, and the rod will drift if air pressure is removed.
