About the Airtac MGC Stainless Steel Mini Cylinder MGC40X500S
The MGC40X500S is a JIS-standard round-body mini cylinder, double acting, with a variable air cushion at both stroke ends. The 40 mm bore delivers 628.3 N push and 527.8 N pull at 0.5 MPa (72.5 psi), rising to 879.6 N push at 0.7 MPa (101.5 psi), with a theoretical maximum of 128.1 kgf at 1.0 MPa (145 psi). The adjustable cushion needles let you dial in smooth deceleration near each end of travel, so this cylinder tolerates higher piston speeds and heavier moving loads than the bumper-style MG without hammering the covers. Stroke is 500 mm, the maximum standard length for this bore, on a 16 mm hard-chrome plated rod with an M14x1.5 male thread and 1/8" ports.
Construction follows the JIS mini-cylinder footprint: a SUS304 stainless barrel with the front and rear covers and stainless block riveted and rolled into place, and a two-way piston seal that also stores lubricant. Operating pressure is 0.15 to 1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature range -20 to +70 C, and speed range 30 to 800 mm/s on air filtered to 40 um. Because the S code is fitted, a magnet is built in and CMSG, DMSG or EMSG switches can be mounted for position feedback. Note that the air cushion only decelerates the piston at end of stroke; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss. A practical sizing insight: the 628.3 N push at 0.5 MPa is about 64 kgf, so a safe continuous vertical lift figure is roughly 38 kg at the usual 0.6 derating.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC40X500S Is Used
High-speed conveyor pusher
The variable air cushion absorbs the momentum of a fast-moving carton or tote at end of stroke, letting the 40 mm bore cycle at speed without cover impact, while the fitted magnet feeds a CMSG switch for cycle confirmation.
Case clamping and ejecting
With 628.3 N push at 0.5 MPa (about 64 kgf), the cylinder clamps or ejects cases and trays on packaging lines, and the adjustable cushion prevents the moving mass from bouncing back off the head.
Slide and gate actuation
The long 500 mm stroke suits sliding guards, chutes and gate mechanisms; LB foot or FA flange mounting plus I or Y rod knuckles keeps the 16 mm chrome rod aligned, and the SUS304 barrel resists washdown corrosion.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC40X500S the Right Cylinder?
Size the MGC40X500S two ways. First, by force: 628.3 N push at 0.5 MPa (72.5 psi) suits loads in the 30 to 40 kg class with a sensible margin; if your supply sits at 0.7 MPa (101.5 psi) you have 879.6 N available. Second, by speed and end-of-stroke behavior: the variable air cushion makes this the right pick over the bumper MG when the piston runs fast or carries a moving mass that would otherwise slam the covers. Within the MGC range, bore 32 gives 402.2 N push at 0.5 MPa and bore 50 gives 981.3 N, so 40 mm sits in the middle; if you do not need cushioning, the plain MG in the same bore is the no-cushion alternative. Mounting is FA flange or LB foot, with I and Y rod knuckles available, and the fitted magnet accepts CMSG, DMSG or EMSG switches. The 500 mm stroke is the maximum standard length for this bore, so keep rod side-loading low: guide the load externally rather than cantilevering it off the 16 mm rod, especially near full extension.

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 MGC40X500S 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 rises to 879.6 N and pull to 738.9 N. The theoretical maximum is 128.1 kgf at 1.0 MPa (145 psi). The 0.5 MPa push equals about 64 kgf, so a safe continuous vertical lift figure is roughly 38 kg using the common 0.6 derating rule.
Adjustable needle valves at both ends throttle the exhausting air so the piston decelerates smoothly into end of stroke; you tune the cushioning to the speed and moving mass. It only cushions, it does not lock or brake: if the load must be held against air loss, add an external rod lock or pilot check valve. The cylinder is JIS round-body with a SUS304 barrel, runs 30 to 800 mm/s at 0.15 to 1.0 MPa (22-145 psi), and the fitted magnet accepts CMSG, DMSG or EMSG switches.
