About the Airtac MGC Stainless Steel Mini Cylinder MGC50X100
The AirTAC MGC50X100 is a double acting, JIS-standard round-body mini cylinder with a 50 mm bore and 100 mm stroke, built with a variable air cushion at both stroke ends. Unlike the bumper-type MG, the cushion needles let you dial in end-of-stroke deceleration, so this cylinder handles higher piston speeds and heavier moving loads without hammering the covers. At 0.5 MPa it 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. The 20 mm hard-chrome plated rod carries an M18x1.5 male thread, and air supply is through 1/4" ports.
Construction follows the JIS mini-cylinder pattern: a SUS304 stainless barrel with the front and back covers and stainless block riveted and rolled into place, no tie-rods and no extruded profile. The two-way piston seal also stores lubricant for long service intervals. Operating pressure spans 0.15 to 1.0 MPa (22 to 145 psi) with 1.5 MPa (215 psi) proof pressure, temperature range -20 to +70 C, and speed range 30 to 800 mm/s. As a computed buyer insight, the 981.3 N push force equals roughly 100 kgf, so a safe working load of about 60 kg is a sensible rule of thumb for horizontal duty. Note that the cushion only decelerates the stroke end; it is not a lock, and the cylinder will not hold position on air loss, so use an external rod lock or pilot check valve for a held load.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC50X100 Is Used
Conveyor stop and divert
The 981.3 N push force at 0.5 MPa stops loaded cartons or totes on powered conveyor lines, while the variable air cushion absorbs the impact of fast-approaching loads at both stroke ends.
Case clamp and eject
Clamping or ejecting filled cases at packaging stations benefits from the adjustable cushion, which prevents the 50 mm piston from slamming the covers during rapid 30 to 800 mm/s cycling.
Machine tool push-off
Pushing finished parts off fixtures or chutes in machining cells, where the roughly 60 kg safe working load rule of thumb and smooth end-of-stroke deceleration protect both part and cylinder.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC50X100 the Right Cylinder?
At 50 mm bore this is the second-largest MGC, pushing 981.3 N at 0.5 MPa (about 100 kgf) and 1373.8 N at 0.7 MPa. If you need more force, step up to the 63 mm bore at 1557.9 N push at 0.5 MPa; if you need less, the 40 mm bore gives 628.3 N. For 20 to 40 mm bores where end-of-stroke damping is not needed, the bumper-type MG is the no-cushion alternative. The variable air cushion is the reason to choose MGC: it absorbs kinetic energy at both stroke ends, which matters at higher speeds or with heavier moving masses. Mount with the FA flange or LB foot, and add I or Y rod knuckles if the tooling needs a pivot. Order the -S magnet option if you want position sensing with CMSG, DMSG or EMSG switches; without the magnet no sensor can be fitted. The 100 mm stroke is well within the 500 mm standard range, but keep side loads off the 20 mm rod on long strokes and guide external loads separately.

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 MGC50X100 FAQ
At 0.5 MPa it pushes 981.3 N and pulls 824.3 N; at 0.7 MPa push is 1373.8 N and pull is 1154 N. The theoretical maximum is 200.1 kgf at 1.0 MPa. Operating pressure is 0.15 to 1.0 MPa (22 to 145 psi) with 1.5 MPa (215 psi) proof pressure.
Yes, both stroke ends have a variable air cushion: turn the needle to set how strongly the piston decelerates, which is ideal at higher speeds or with heavier moving loads. The cushion only slows the piston near the end of stroke; it is not a brake, and the MGC does not hold position if air is lost, so fit an external rod lock or pilot check valve for a held load.
