About the Airtac MGC Stainless Steel Mini Cylinder MGC40X360S
The AirTAC MGC40X360S is a JIS-standard round-body mini cylinder, double acting, with a variable air cushion at both stroke ends. At 40 mm bore it delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa (72.5 psi), rising to 879.6 N push at 0.7 MPa (101.5 psi). The adjustable cushion needle lets you dial in smooth deceleration near end of travel, so this cylinder handles higher piston speeds and heavier moving loads than the bumper-type MG without hammering the covers. The 360 mm stroke sits well inside the 500 mm maximum standard stroke for this bore, so it ships as a standard catalog item.
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) 16 mm carbon-steel rod with an M14x1.5 male thread. The two-way piston seal also stores lubricant for long service life. Operating pressure is 0.15 to 1.0 MPa (22 to 145 psi) with proof pressure of 1.5 MPa (215 psi), speed range 30 to 800 mm/s, and temperature from -20 to +70 C. The fitted magnet (the S in the code) accepts CMSG, DMSG or EMSG reed switches for position sensing. Note that the air cushion only decelerates the piston near end of stroke; it is not a lock or brake, 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 MGC40X360S Is Used
Conveyor stop and divert
The variable air cushion absorbs the impact of fast-moving cartons or pallet stops at 30 to 800 mm/s, protecting the covers where a bumper-only MG would hammer.
Packaging pusher and ejector
With 628.3 N push at 0.5 MPa (about 64 kgf), the 40 mm bore ejects boxes or trays from a packaging line, and the fitted magnet feeds CMSG or DMSG switches for end-position confirmation.
Machine slide actuation
The 360 mm stroke and adjustable end-of-stroke deceleration suit longer machine slides and indexing fixtures, with FA flange or LB foot mounting to match the layout.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC40X360S the Right Cylinder?
Size the MGC40X360S by force and by cushion need. At 0.5 MPa (72.5 psi) the 40 mm bore pushes 628.3 N, about 64 kgf; a safe working load rule of 0.6x that push gives roughly 38 kg for horizontal duty, and for vertical lifting halve it to about 32 kg. If your load is lighter, the MGC32 offers 402.2 N push at 0.5 MPa; if heavier, step up to the MGC50 at 981.3 N. For bores 20 to 40 the plain MG is the no-cushion alternative if you do not need adjustable deceleration, but at higher speeds or with heavy moving loads the variable air cushion here is worth it. Mounting is FA flange or LB foot, with I and Y rod knuckles available, and ports are 1/8". The 360 mm stroke is long for a mini cylinder, so watch side loading on the 16 mm rod and use a guide if the load is not well aligned. Add -S sensing (already fitted here) with CMSG, DMSG or EMSG switches.

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 MGC40X360S FAQ
At 0.5 MPa (72.5 psi) it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa (101.5 psi) push is 879.6 N and pull 738.9 N. Theoretical maximum is 128.1 kgf at 1.0 MPa. A practical rule of thumb is 0.6x the push force, so about 38 kg safe horizontal working load, or roughly 32 kg for vertical lift.
The cushion is an adjustable air restriction at both stroke ends; turning the needle changes how strongly the trapped air decelerates the piston, letting you run higher speeds without impact. It only decelerates end of stroke and is not a lock or brake, so the cylinder will not hold position on air loss. Use an external rod lock or pilot check valve for a held load. The barrel is SUS304 stainless with a hard-chrome plated rod, JIS round-body construction.
