About the Airtac MGC Stainless Steel Mini Cylinder MGC20X350S
The AirTAC MGC20X350S is a double acting, JIS-standard round-body mini cylinder with a 20 mm bore and a 350 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-style MG, the cushion needles let you dial in smooth deceleration near end of travel, so this 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 and 184.7 N pull 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 into place, plus a hard-chrome plated (20 um) 8 mm carbon-steel rod with an M8x1.25 male thread. Air supply is M5x0.8 on both ports, operating pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, temperature range is -20 to +70 C, and speed runs 30-800 mm/s. Because the S code magnet is fitted, CMSG, DMSG or EMSG switches can be mounted 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 MGC20X350S Is Used
High-cycle parts ejection
At 30-800 mm/s with adjustable cushioning, the MGC20X350S can run fast push-off strokes on small sorting or eject stations, decelerating smoothly instead of slamming the head cover.
Light packaging pushers
With 157 N push at 0.5 MPa (about 16 kgf), it slides small cartons or blisters off a conveyor lane, while the 350 mm stroke clears a wide product pitch.
Position-monitored test fixtures
The fitted magnet accepts CMSG, DMSG or EMSG switches, so the stroke can report extend and retract positions to a PLC in bench-top or small assembly fixtures.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC20X350S the Right Cylinder?
Bore 20 is the smallest MGC size, so choose MGC20X350S when your budget of force is modest: 157 N push at 0.5 MPa works out to roughly 16 kgf, and a safe vertical lift figure is about 8 kg (half of that). If you need more muscle, step up to the 25 mm bore (245.3 N push at 0.5 MPa) or the 32 mm bore (402.2 N). If your application is slow and light and you do not need end-of-stroke damping, the plain bumper MG in the same bore is the lower-cost alternative for 20-40 mm bores. The 350 mm stroke sits comfortably inside the 500 mm maximum standard stroke for this bore, so it ships as a standard item; strokes up to 800 mm are made to order. Mount with the FA flange or LB foot, add I or Y rod knuckles if the tooling needs a pivot, and keep the -S in the code if you want CMSG/DMSG/EMSG sensing. At this stroke, watch side loading: the 8 mm rod has limited bending capacity, so guide external loads separately rather than cantilevering them off the rod.

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 MGC20X350S FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N; at 0.7 MPa those rise to 219.8 N push and 184.7 N pull. The theoretical maximum at 1.0 MPa is 32 kgf. In practice, size the load at about 0.6 of the 0.5 MPa push force, roughly 9.5 kgf, and about half that for vertical lifting.
The cushion is an adjustable air dam at both stroke ends: turn the needle to throttle exhaust near end of travel and decelerate the piston smoothly, which suits higher speeds and heavier moving loads than the fixed-bumper MG. Because the S code magnet is fitted, CMSG, DMSG or EMSG reed switches can be clipped onto the SUS304 barrel for position sensing.
