About the Airtac MGC Stainless Steel Mini Cylinder MGC50X100S
The AirTAC MGC50X100S is a double acting, JIS-standard round-body mini cylinder with a 50 mm bore and 100 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 a push force of 981.3 N and a pull force of 824.3 N; at 0.7 MPa those rise to 1373.8 N and 1154 N, 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) 20 mm carbon-steel rod with an M18x1.5 male thread and 1/4" ports. The two-way piston seal also stores lubricant for long service life. Because the S code is present, a magnet is built in and CMSG, DMSG or EMSG switches can be clipped on for position sensing. One practical note: the air cushion only decelerates the stroke end, it is not a lock or brake, so for a held load add an external rod lock or pilot check valve. As a computed buyer insight, the 981.3 N push at 0.5 MPa equals about 100 kgf, so a safe working figure for vertical lifting is roughly 60 kg.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC50X100S Is Used
Pallet push-off stations
The 981.3 N push at 0.5 MPa moves loaded pallets or tote bins clear of a conveyor stop, and the adjustable cushion stops the mass smoothly at high cycle rates.
Light press and staking
With 1373.8 N available at 0.7 MPa, the 50 mm bore suits light pressing, snapping and staking jobs where the cushion absorbs the impact at bottom of stroke.
Conveyor diverters and gates
Fast diverting gates benefit from the variable air cushion at both ends, and the fitted magnet with CMSG/DMSG/EMSG switches confirms gate open and closed positions.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC50X100S the Right Cylinder?
Sizing: at 0.5 MPa the 50 mm bore pushes 981.3 N (about 100 kgf), comfortably above the 628.3 N of the 40 mm MGC and below the 1557.9 N of the largest MGC, the 63 mm bore. If you do not need end-of-stroke deceleration, the plain bumper MG is the no-cushion alternative, but it stops at 40 mm, so the MGC is also the route to 50 mm and 63 mm bores in this family. The variable air cushion is the main reason to choose this model when cycle speeds are high or the moving mass is heavy. Mounting is by FA flange or LB foot, with I and Y rod knuckles available as accessories. The -S code means the magnet is fitted for CMSG/DMSG/EMSG switches. The 100 mm stroke is well inside the 500 mm standard range, but on long strokes keep the rod side load low or add external guidance to protect the hard-chrome rod and seals.

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 MGC50X100S FAQ
At 0.5 MPa it pushes 981.3 N and pulls 824.3 N; at 0.7 MPa, 1373.8 N push and 1154 N pull. The theoretical maximum is 200.1 kgf at 1.0 MPa. A common rule of thumb is to size at about 0.6 of the push force, so roughly 60 kg is a safe vertical lifting figure.
Adjustable cushion needles at both stroke ends throttle the exhaust air to decelerate the piston smoothly, which suits speeds up to 800 mm/s and heavy moving loads. The cushion is not a brake or lock: on air loss the MGC50X100S will not hold position, so use an external rod lock or pilot check valve for a held load.
