About the Airtac MGC Stainless Steel Mini Cylinder MGC50X150
The AirTAC MGC50X150 is a JIS-standard round-body mini cylinder, double acting, with a variable air cushion at both stroke ends. The cushion needles let you dial in end-of-stroke deceleration, so at the higher end of the 30-800 mm/s speed range the piston settles smoothly instead of hammering the covers - a real advantage over the fixed-bumper MG when the moving load is heavy. With a 50 mm bore this model delivers 981.3 N push and 824.3 N pull at 0.5 MPa (72.6 psi), rising to 1373.8 N push at 0.7 MPa (101.5 psi), with a theoretical maximum of 200.1 kgf at 1.0 MPa (145 psi).
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) 20 mm rod with M18x1.5 male thread. The two-way piston seal also stores lubricant, and ports are 1/4". Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof pressure 1.5 MPa (215 psi), over -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 MGC50X150 Is Used
High-speed push stations
The variable air cushion absorbs the end-of-stroke energy of fast cycles, so a 50 mm bore pushing around 60 kgf safely at 0.5 MPa can run near the top of the 30-800 mm/s range without cover impact.
Conveyor divert and stopper actuation
Adjustable deceleration at both ends suits diverters and stoppers on packaging lines, where the 150 mm stroke and 981.3 N push at 0.5 MPa handle heavier product streams smoothly.
Packaging clamp and press-fit fixtures
With 1373.8 N push at 0.7 MPa (101.5 psi) and a hard-chrome 20 mm rod, this cylinder clamps or lightly presses cartons, trays and fittings in JIS-footprint machinery.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC50X150 the Right Cylinder?
At 50 mm bore, the MGC50X150 sits in the upper half of the MGC range: 981.3 N push at 0.5 MPa (72.6 psi) gives a safe working push of roughly 60 kgf (about 0.6x the theoretical force), and roughly 42 kgf if the same force is used for vertical lifting. Step down to the 40 mm bore (628.3 N push at 0.5 MPa) if space is tight, or up to the 63 mm bore (1557.9 N) when more force is needed. For 20-40 mm bores, the plain bumper MG is the no-cushion alternative; at 50 and 63 mm the cushioned MGC is the only option in this family. The 150 mm stroke is well within the 500 mm standard range, and non-standard strokes up to 800 mm are made to order. Mount with the FA flange or LB foot, add I or Y rod knuckles where the tooling needs a pivot, and order the -S suffix if you plan to fit CMSG, DMSG or EMSG sensors - without the magnet no sensor can be mounted. Because this is a round-body cylinder, support long strokes against side load.

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 MGC50X150 FAQ
At 0.5 MPa (72.6 psi) it pushes with 981.3 N and pulls with 824.3 N; at 0.7 MPa (101.5 psi) push is 1373.8 N and pull is 1154 N. The theoretical maximum is 200.1 kgf at 1.0 MPa (145 psi). A practical rule of thumb is to size the load at about 0.6x the push force, so roughly 60 kgf horizontal; for vertical lifting halve that to about 42 kgf.
The needle valves at both ends throttle the exhaust near end of stroke, giving adjustable deceleration - ideal at higher speeds or with heavier moving loads. The cushion only slows the piston; it is not a lock or brake, and the MGC50X150 does not hold position on air loss. For a held load, add an external rod lock or pilot check valve. Position sensing requires the -S magnet option with CMSG, DMSG or EMSG switches.
