About the Airtac MG Stainless Steel Mini Air Cylinder MG40X460S
The MG40X460S is a double acting, JIS-standard round-body mini cylinder from AirTAC with a 40 mm bore and a long 460 mm stroke. Air drives the rod in both directions, and at 0.5 MPa it delivers 628.3 N on the push stroke, which works out to roughly 377 N of usable force if you plan around 60 percent of the rating. In vertical terms that push equals about 64 kgf, so with a 2:1 margin this cylinder lifts about 32 kg vertically. The 460 mm stroke sits inside the 500 mm standard range for the 40 mm bore, so no made-to-order stroke is needed.
The body is a SUS304 stainless barrel with a hard-chrome plated 16 mm rod, riveted together with the covers into a compact round package that shrugs off damp, washdown-prone and outdoor spots better than painted-steel minis. Because the MG follows the JIS mini-cylinder standard, its mounting footprint drops into standard JIS brackets and rod knuckles, which makes spares and redesigns simple. A fixed anti-impact pad at each stroke end softens the direction change, and the built-in magnet lets CMSG, DMSG or EMSG switches report rod position without any retrofit.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG40X460S Is Used
Bottling line pusher
Pushes full crates sideways off a beverage conveyor; 628.3 N at 0.5 MPa moves loaded crates while the SUS304 barrel handles frequent washdown.
Lid-lift on a packaging machine
Raises roughly 32 kg carton lids vertically on a 2:1 margin, with the 460 mm stroke clearing tall stack heights and the magnet confirming open position.
Gate actuator on an outdoor saw station
Swings a timber-mill dust gate via a CB clevis; the stainless round body and hard-chrome rod resist weathering, and the bumper pad softens each stroke end.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG40X460S the Right Cylinder?
At 40 mm bore this is the largest base MG, pushing 628.3 N at 0.5 MPa. If your load needs less, the 32 mm bore (402.2 N push at 0.5 MPa) saves space and air; if you need more force or adjustable end-of-stroke deceleration at higher speeds, step up to the cushioned MGC series, which extends to 50 and 63 mm bores. With a 460 mm stroke, keep the rod side-loaded minimally and guide the load externally, since a long thin rod bends under side forces. Note that when air is removed or the valve is centred, the piston drifts freely - for a load that must stay put, add an external rod lock or a pilot check valve. The magnet is already fitted, so CMSG / DMSG / EMSG switches work out of the box; choose LB foot, FA flange, CB clevis or SDB pivot mounting and PT, G or NPT ports when ordering.

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/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MG Stainless Steel Mini Air Cylinder MG40X460S FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum is 128.1 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, speed range 30-800 mm/s, and the port is 1/8".
Yes. The S in MG40X460S means the piston magnet is built in, so AirTAC CMSG, DMSG or EMSG reed/electronic switches clamp directly onto the stainless barrel to signal extend or retract. The fixed anti-impact pads at the stroke ends only soften the impact - they do not cushion adjustably or hold the load when air is lost.
