About the Airtac MGC Stainless Steel Mini Cylinder MGC40X200S
The AirTAC MGC40X200S is a double acting, JIS-standard round-body mini cylinder with a 40 mm bore and 200 mm stroke, fitted with a variable air cushion at both ends. Unlike the bumper-type MG, the cushion needles let you dial in end-of-stroke deceleration, so this cylinder can run at higher piston speeds (up to 800 mm/s) and carry heavier moving loads without hammering the covers. At 0.5 MPa it delivers 628.3 N of push force and 527.8 N of pull, rising to 879.6 N push at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa. The -S code means a magnet is built into the piston, so CMSG, DMSG or EMSG reed switches can be slid onto the barrel for position feedback.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with the front and back covers riveted and rolled into place, plus a 16 mm hard-chrome plated (20 um) carbon-steel rod with M14x1.5 male thread. The two-way piston seal also stores lubricant for long maintenance intervals. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, over a temperature range of -20 to +70 C, using air filtered to 40 um. As a rule of thumb, halve the 0.5 MPa push force for a safe vertical lift of roughly 38 kg on this model. Mounting is via LB foot or FA flange, with I and Y rod knuckles available.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC40X200S Is Used
High-speed pusher on packaging lines
The variable air cushion absorbs end-of-stroke energy at speeds up to 800 mm/s, letting this 628.3 N cylinder eject cartons or trays fast without cover impact.
Conveyor divert and stop stations
Adjustable deceleration at both ends suits repeated diverting or stopping of product flow, with the -S magnet feeding CMSG or DMSG switches for position confirmation.
Light press and forming fixtures
With 879.6 N push at 0.7 MPa (about 64 kgf at 0.5 MPa, roughly 38 kg safe vertical lift), the MGC40X200S handles small staking, marking and assembly presses.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC40X200S the Right Cylinder?
At 40 mm bore, the MGC40X200S sits in the upper-middle of the MGC range: 628.3 N push at 0.5 MPa, about 64 kgf, with 879.6 N available at 0.7 MPa. Size down to the 32 mm bore (402.2 N push) if force is generous, or up to 50 mm (981.3 N) and 63 mm (1557.9 N) for heavier loads. If you do not need end-of-stroke deceleration, the bumper-type MG covers bores 20-40 as a lower-cost alternative. The 200 mm stroke is well within the 500 mm maximum standard stroke for this bore, so it ships as a catalog item; strokes up to 800 mm are made to order. Choose the -S magnet (as here) if you need CMSG/DMSG/EMSG sensing, and pick LB foot or FA flange mounting plus I or Y rod knuckles to suit your fixture. With a 200 mm stroke, verify rod alignment and side load: the 16 mm hard-chrome rod tolerates only modest lateral forces, so use guides if the load overhangs.

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 MGC40X200S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa that rises to 879.6 N push and 738.9 N pull, with a theoretical maximum of 128.1 kgf at 1.0 MPa. For sizing, treat about 0.6 of the 0.5 MPa push force as a safe working load, roughly 38 kg for vertical lifting.
The cushion is an adjustable air cushion at both stroke ends: turn the needle valve to decelerate the piston smoothly before it reaches the cover, which permits higher speeds and heavier moving loads than the fixed-bumper MG. It only decelerates the stroke end - it is not a lock or brake, and the cylinder will not hold position on air loss. Use an external rod lock or pilot check valve for a held load.
