About the Airtac MGC Stainless Steel Mini Cylinder MGC20X100S
The AirTAC MGC20X100S is a double acting, JIS-standard round-body mini cylinder with a 20 mm bore and 100 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-style MG, the cushion needles can be adjusted to decelerate the piston smoothly near end of travel, so this compact 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 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 and a two-way piston seal that also stores lubricant. The S code means a magnet is built in, so CMSG, DMSG or EMSG switches can be mounted for position feedback. Operating range is 0.15 to 1.0 MPa (22 to 145 psi), speed 30 to 800 mm/s, temperature -20 to +70 C, with an M5x0.8 port and PT thread. As a sizing rule of thumb, treat about 0.6 of the push force as the safe working load, roughly 94 N, or about 8 kg for vertical lifting.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC20X100S Is Used
Small parts ejection
Pushes finished components off a fixture or nest at the end of a cycle; the adjustable air cushion stops the piston gently at high cycle speeds, protecting the 20 mm bore covers.
Conveyor diverting and stopping
Acts as a compact pusher or stopper on light product lines, where the variable cushion absorbs the moving load without the bounce of a fixed pad.
Indexing and clamping slides
Drives a small slide or clamp on automated equipment, with CMSG/DMSG/EMSG switches on the magnet confirming extend and retract positions.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC20X100S the Right Cylinder?
At 20 mm bore this is the smallest MGC available, so there is no smaller cushioned option in the family; if you need more force, step up to the 25 mm bore (245.3 N push at 0.5 MPa) or beyond, up to the 63 mm bore at 1557.9 N. If your application runs slowly with light loads and does not need end-of-stroke deceleration, the plain bumper-type MG in the same 20 mm bore is the lower-cost alternative. Choose the MGC20X100S when speed or moving mass calls for an adjustable cushion. The S suffix gives you a magnet for CMSG/DMSG/EMSG sensing; mounting is FA flange or LB foot, with I and Y rod knuckles available. The 8 mm rod suits short and medium strokes; for strokes near the 500 mm standard maximum, support the rod or add a guide to limit side load, and note that strokes up to 800 mm are made to order.

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 MGC20X100S FAQ
At 0.5 MPa the 20 mm bore gives 157 N push and 131.9 N pull. At 0.7 MPa that rises to 219.8 N push and 184.7 N pull, and the theoretical maximum is 32 kgf at 1.0 MPa. For sizing, keep the working load near 0.6 of the push force, about 94 N or roughly 8 kg vertical.
The cushion is a variable air cushion at both stroke ends: turn the needle valve to meter the exhaust and decelerate the piston smoothly before it reaches the cover. It only slows the piston near end of travel; it is not a lock or brake, and the cylinder will not hold position if air is lost. For a suspended or held load, add an external rod lock or pilot-operated check valve.
