About the Airtac MG Stainless Steel Mini Air Cylinder MG32X450S
With a 32 mm bore pushing 402.2 N at 0.5 MPa (563 N at 0.7 MPa), this double acting MG32X450S covers mid-range clamping, lifting and feeding over a long 450 mm stroke. The round barrel is rolled from SUS304 stainless steel onto the covers, so the body shrugs off washdown and damp shop air far better than painted minis, while the hard-chrome plated 12 mm rod keeps seal wear low. It follows the JIS mini-cylinder standard, so standard JIS brackets and rod knuckles bolt straight on.
The 450 mm stroke ends on a fixed anti-impact bumper pad that softens direction change at speed - it decelerates, it is not an adjustable air cushion. Because the magnet is built in (the S code), CMSG, DMSG or EMSG switches can be clipped on anywhere along the barrel for end-of-stroke signalling. As a working rule, size the job to about 240 N of push force at 0.5 MPa, which is roughly 24 kg of vertical lift with margin to spare.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X450S Is Used
Packaging line reject pusher
The 402.2 N push at 0.5 MPa kicks misaligned cartons or trays off a conveyor across a 450 mm span, and the bumper pad absorbs the stop at each cycle.
Bottle-riser lifting station
With about 24 kg of practical vertical lift at 0.5 MPa, the cylinder raises bottles or small containers on a filling carousel; the built-in magnet feeds position signals to the PLC.
Lab sample gate actuator
In automated sample handling, the SUS304 stainless barrel tolerates frequent wipe-downs, and the long stroke slides gates or trays between two stations.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X450S the Right Cylinder?
At 402.2 N push and 345.6 N pull at 0.5 MPa, the 32 mm bore sits between the 25 mm MG (245.3 N push) and the 40 mm MG (628.3 N push). If your load needs under about 240 N of working force, step down to the 25 mm bore; if you need over 400 N, go to 40 mm or the cushioned MGC, which extends the range to Dia 50 and 63. For long 450 mm strokes, watch side loads: the 12 mm rod tolerates little bending, so guide the load externally rather than letting the rod carry it. Mounting choices are LB foot, FA flange, CB clevis or SDB pivot, and I or Y knuckles take the rod side. Note that this cylinder does not hold position when air is lost - the piston drifts freely - so add an external rod lock or a pilot check valve if the load must stay put. Ports are 1/8" on every MG bore.

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 MG32X450S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa, 563 N push and 483.8 N pull. The theoretical maximum is 82 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and rod speed runs 30-800 mm/s.
The S means a piston magnet is built in, which is what lets CMSG, DMSG or EMSG reed/electronic switches detect position along the stainless barrel. A plain MG32X450 without the S has no magnet, so switches cannot sense it - order the S version if you need end-of-stroke feedback.
