About the Airtac MG Stainless Steel Mini Air Cylinder MG32X350S
With a 32 mm bore pushing 402.2 N at 0.5 MPa (563 N at 0.7 MPa), this 350 mm stroke MG32X350S is a double acting JIS round-body mini cylinder built around a riveted SUS304 stainless barrel and a hard-chrome plated 12 mm rod. The stainless construction shrugs off washdown, humidity and outdoor exposure far better than painted-steel minis, and because the MG follows the JIS mini-cylinder standard, its mounting and accessory footprint drops straight into standard JIS brackets and I/Y rod knuckles.
The fitted magnet (the S in the code) lets CMSG, DMSG or EMSG switches report end-of-stroke positions without any retrofit. At the stroke ends, fixed anti-impact bumper pads decelerate the piston to soften direction changes - they are not an adjustable air cushion. As a working rule, plan on roughly 241 N (about 24 kgf) of usable push at 0.5 MPa, or around 20 kg of vertical lifting capacity with a 2:1 margin, so you can match real part weights before ordering.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X350S Is Used
Bottling line pusher
Ejecting or lane-diverting PET bottles and cartons on a washdown conveyor, where the 402.2 N push at 0.5 MPa and the SUS304 barrel handle wet, corrosive conditions.
Small parts press station
Light pressing and staking of bushings or terminals in electronics assembly, using about 241 N of practical working force at 0.5 MPa over the 350 mm reach.
Position-flagged lift fixture
Raising jigs or lids of about 20 kg vertically with a 2:1 margin, with CMSG switches on the fitted magnet confirming up and down positions to the PLC.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X350S the Right Cylinder?
At 32 mm bore this sits mid-range: the 25 mm MG delivers about 245 N push at 0.5 MPa, while stepping up to the 40 mm MG raises that to about 628 N - pick the 32 if your load falls between roughly 150 and 400 N. Note that a plain MG does not hold position when air is lost or the valve centres; the rod drifts, so add an external rod lock or a pilot check valve for held loads. The 350 mm stroke is within the 500 mm standard range for this bore, but long strokes are more sensitive to side load - keep the rod aligned or add a guide. Mount with LB foot, FA flange, CB clevis or SDB pivot; the magnet is already fitted for CMSG/DMSG/EMSG switches, and ports are 1/8" with PT thread.

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 MG32X350S FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N; at 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum is 82 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, and speed spans 30-800 mm/s.
Yes. The S in MG32X350S means a magnet is built into the piston, so AirTAC CMSG, DMSG or EMSG switches can be clipped onto the 32 mm barrel to signal stroke-end positions. The fixed bumper pads at each end only soften the stroke-end impact - they are not an adjustable cushion and do not hold a load if air pressure is lost.
