About the Airtac MGC Stainless Steel Mini Cylinder MGC25X150
The AirTAC MGC25X150 is a double acting, JIS-standard round-body mini cylinder with a 25 mm bore and 150 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-type MG, the cushion needles can be adjusted to decelerate the piston smoothly near end of travel, so this 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 at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated (20 um) 10 mm carbon-steel rod with M10x1.25 male thread. The two-way piston seal also stores lubricant for long service life. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and temperature range -20 to +70 C, on air filtered to 40 um. Ports are 1/8". 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 MGC25X150 Is Used
High-cycle pusher on small assembly stations
The variable air cushion lets the 25 mm bore run at higher speeds (up to 800 mm/s) and decelerate parts smoothly at end of stroke, avoiding cover impact in fast eject or push-off positions.
Packaging gate and flap actuation
With 245.3 N push at 0.5 MPa, the MGC25X150 swings gates, diverts cartons and trips flaps, while the adjustable cushion stops the mechanism quietly at both ends.
Light clamping and positioning fixtures
About 25 kgf of push force with JIS-consistent mounting (FA flange or LB foot) makes this cylinder a compact drop-in for jigs and fixtures needing controlled, cushioned approach.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC25X150 the Right Cylinder?
At 25 mm bore, the MGC25X150 sits one step above the smallest MGC (20 mm, 157.0 N push at 0.5 MPa) and below the 32 mm (402.2 N). If you do not need cushioning, the bumper-type MG covers 20-40 mm as a simpler alternative. The 245.3 N push force at 0.5 MPa equates to about 25 kgf; applying the usual 0.6 safety factor gives roughly 15 kg as a safe working load, or about 12.5 kg for vertical lifting. Choose the optional S code (magnet) if you need CMSG, DMSG or EMSG position sensors - without it no sensor can be mounted. Mounting is FA flange or LB foot, with I and Y rod knuckles for the rod side; thread options are PT (blank), G or NPT. The 150 mm stroke is well within the 500 mm standard range for this bore, and strokes up to 800 mm are made to order. On long strokes, guide the load externally to keep side loads off the hard-chrome 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 MGC25X150 FAQ
At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa those figures rise to 343.4 N push and 288.5 N pull. The theoretical maximum is 50 kgf at 1.0 MPa. Applying a 0.6 safety factor to the 0.5 MPa push force gives roughly 15 kg as a safe working load.
Both stroke ends have a variable air cushion: turn the cushion needle to meter exhaust and decelerate the piston smoothly - it is adjustable, not a fixed pad, and it decelerates only (it does not lock or hold the load). The cylinder is double acting with a SUS304 stainless barrel and hard-chrome rod. Adding the S code (magnet) enables CMSG, DMSG or EMSG reed sensors; this MGC25X150 has no magnet, so no sensor can be mounted as ordered.
