About the Airtac MGC Stainless Steel Mini Cylinder MGC25X175
The AirTAC MGC25X175 is a JIS-standard round-body mini cylinder, double acting, with a variable air cushion at both stroke ends. The 25 mm bore delivers 245.3 N push and 206.1 N pull at 0.5 MPa (343.4 N / 288.5 N at 0.7 MPa), with a theoretical maximum of 50 kgf at 1.0 MPa. The adjustable cushion needles let you dial in smooth piston deceleration near each end of the 175 mm stroke, so this cylinder tolerates higher speeds and heavier moving loads than the bumper-type MG without hammering the covers.
Construction follows the MG family recipe: a 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. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature -20 to +70 C, and speed 30-800 mm/s. Ports are 1/8", the male rod thread is M10x1.25, and the rod is 10 mm. Note that the cushion only decelerates end of stroke; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC25X175 Is Used
Conveyor stop and divert
The 245.3 N push at 0.5 MPa stops cartons on light conveyor lines, while the variable air cushion absorbs the moving mass at end of stroke when lines run fast.
Small parts ejection
Pushes machined or molded parts off chutes and fixtures at up to 800 mm/s; the adjustable cushion prevents the part or the covers taking an impact at stroke end.
Packaging pusher arms
Drives pusher and gate arms on packaging machinery where the 175 mm stroke and cushioned ends let products settle into position without bounce or hammer.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC25X175 the Right Cylinder?
At 25 mm bore the MGC25X175 sits just above the smallest cushioned MGC (bore 20, 157.0 N push at 0.5 MPa); stepping up to 32 mm gives 402.2 N if you need more force. If your application runs slow with light loads and no cushion is needed, the plain bumper MG in the same bore is the alternative for 20-40 mm. Size by the real 0.5 MPa push figure: 245.3 N is about 25 kgf, so a safe vertical lift rule of thumb (roughly 0.6 of push force) is about 15 kg. Mounting is FA flange or LB foot, with I and Y rod knuckles available. Add the S magnet code if you want CMSG / DMSG / ESG-style position sensing - this no-S model carries no magnet and accepts no sensor. At 175 mm stroke the 10 mm rod is fine in-line, but for long strokes guard against side load on the rod.

- ✓ Mounting (LB / FA) & 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 and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGC Stainless Steel Mini Cylinder MGC25X175 FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa, 343.4 N push and 288.5 N pull. The theoretical maximum at 1.0 MPa is 50 kgf. A practical safe vertical lift figure is about 15 kg (roughly 0.6 of the 0.5 MPa push force).
Needle valves at each end throttle the exhaust air to decelerate the piston smoothly before it reaches the cover - adjust them to suit speed and load. The cushion only slows end of stroke; it is not a brake or lock, so for a held load fit an external rod lock or pilot check valve. The SUS304 stainless barrel and hard-chrome rod suit washdown-prone areas, and mounting is FA flange or LB foot.
