About the Airtac MGC Stainless Steel Mini Cylinder MGC50X150SCB
The AirTAC MGC50X150SCB is a double acting, JIS-standard round-body mini cylinder with a 50 mm bore and 150 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-style MG, the cushion needles are adjustable, so you can dial in smooth deceleration near end of travel when the piston is running fast or carrying a heavier moving load. At 0.5 MPa this bore delivers 981.3 N push and 824.3 N pull, rising to 1373.8 N push at 0.7 MPa, with a theoretical maximum of 200.1 kgf at 1.0 MPa.
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 (20 mm diameter, male thread M18x1.5) and a two-way piston seal that also stores lubricant. The 1/4" ports take PT thread, and the fitted magnet (the S code) allows CMSG, DMSG or EMSG switch mounting. Operating range is 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, -20 to +70 C, on air filtered to 40 um. Note that the cushion only decelerates the stroke end; 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 MGC50X150SCB Is Used
High-speed carton press and seal
The 981.3 N push at 0.5 MPa presses flaps or seals at conveyor pace, while the variable air cushion absorbs the end-of-stroke impact so the fixture does not hammer at 500+ mm/s.
Conveyor line divert and stop
Fast-acting diverters and stoppers benefit from adjustable deceleration at both ends, and the fitted magnet feeds a CMSG or DMSG switch to confirm extend and retract positions.
Clamping on light machining fixtures
With 1373.8 N push at 0.7 MPa (about 140 kgf) and an LB foot or FA flange mount, the cushioned 50 mm bore clamps jigs smoothly without shocking the fixture at cycle end.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC50X150SCB the Right Cylinder?
At 50 mm bore this is one of the two largest MGC sizes, second only to the 63 mm bore (1557.9 N push at 0.5 MPa) and well above the 40 mm bore (628.3 N). If you do not need cushioning and stay at 40 mm bore or below, the bumper-style MG is the no-cushion alternative in the same JIS footprint. Use the 0.5 MPa push force of 981.3 N (about 100 kgf) as your sizing baseline and keep the working load near 0.6x of that, roughly 60 kg, for a margin-safe selection; for vertical lifting halve it to about 50 kg. The 150 mm stroke sits comfortably inside the 500 mm standard range for this bore, but keep rod side loads low on longer strokes. Mount with the FA flange or LB foot, add I or Y rod knuckles where the tooling needs a swivel, and the fitted magnet means CMSG, DMSG or EMSG switches can be clipped on for position feedback.

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 MGC50X150SCB FAQ
At 0.5 MPa it pushes 981.3 N and pulls 824.3 N; at 0.7 MPa it pushes 1373.8 N and pulls 1154 N. The theoretical maximum force at 1.0 MPa is 200.1 kgf. A practical safe working load is about 0.6x the 0.5 MPa push force, roughly 60 kg.
Needle valves at both stroke ends throttle the exhaust to decelerate the piston smoothly; adjust them to suit speed and load. Yes - this model carries the S magnet code, so CMSG, DMSG or EMSG switches mount directly on the SUS304 stainless barrel.
