About the Airtac MGC Stainless Steel Mini Cylinder MGC20X200S
The AirTAC MGC20X200S is a double acting, JIS-standard round-body mini cylinder with a 20 mm bore and 200 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the fixed bumper pad on the plain MG, this adjustable cushion lets you tune the needle valve to decelerate the piston smoothly near end of travel, so the cylinder tolerates higher piston speeds and heavier moving loads without hammering the covers. At 0.5 MPa it delivers 157 N push and 131.9 N pull, rising to 219.8 N push at 0.7 MPa, with a theoretical maximum of 32 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) carbon-steel rod with a two-way piston seal that also stores lubricant. The 8 mm rod carries an M8x1.25 male thread and air is supplied through M5x0.8 ports. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof rating, speed range is 30-800 mm/s, and temperature spans -20 to +70 C. The fitted magnet (the S code) allows CMSG, DMSG or EMSG switches to be clipped on for position feedback. 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 MGC20X200S Is Used
High-cycle ejection on small assembly stations
The variable air cushion lets this 20 mm bore run at the upper end of its 30-800 mm/s range, decelerating the 157 N push stroke smoothly so light punch or ejector tools do not slam the covers at cycle rates a bumper cylinder cannot match.
Sorting gate and diverter actuation
Pushing small parcels or parts off a conveyor line, the MGC20X200S gives 219.8 N at 0.7 MPa with adjustable end-of-stroke damping, and the fitted magnet feeds CMSG or DMSG switches to confirm gate position back to the PLC.
Compact press and clamping fixtures
With about 9.5 kg safe working load from the 157 N push force and FA flange or LB foot mounting, this cylinder suits light clamping and small press-fit jigs where the cushion absorbs the final seating impact.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC20X200S the Right Cylinder?
At 20 mm bore this is the smallest MGC in the range, so there is no smaller cushioned option to step down to; if 157 N push at 0.5 MPa is marginal, step up to the 25 mm bore (245.3 N) or 32 mm bore (402.2 N). If you do not need adjustable deceleration, the bumper-type MG in the same 20 mm bore is the no-cushion alternative. Size the load conservatively: 157 N at 0.5 MPa is about 16 kgf, so roughly 9.5 kg is a safe working figure, and for vertical lifting halve it to about 8 kg. The 200 mm stroke sits well inside the 500 mm maximum standard stroke, so no made-to-order surcharge applies. Mount with the FA flange or LB foot, add I or Y rod knuckles if the load pivots, and remember the S magnet is what enables CMSG/DMSG/EMSG sensing. At longer strokes or higher speeds, guide side loads externally so the 8 mm rod is not loaded radially.

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 MGC20X200S FAQ
At 0.5 MPa the 20 mm bore pushes 157 N and pulls 131.9 N; at 0.7 MPa that rises to 219.8 N push and 184.7 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. In practice, size the load at about 0.6 of the push force, roughly 9.5 kg, and about 8 kg for vertical lifting.
The cushion is an adjustable air chamber at each stroke end: a needle valve meters the exhaust so the piston decelerates smoothly instead of striking the cover, which is what lets the MGC run faster and carry heavier moving loads than the bumper-type MG. It only slows the piston near the end of travel; it is not a brake or lock, so fit an external rod lock or pilot check valve if the load must stay in place on air loss.
