About the Airtac MG Stainless Steel Mini Air Cylinder MG32X500S
With a 32 mm bore pushing about 402 N at 0.5 MPa, this MG32X500S is a double acting JIS round-body mini cylinder built for long-travel work on compact machines. The 500 mm stroke is the maximum standard length for this bore, and the riveted SUS304 stainless barrel with a hard-chrome plated 12 mm rod shrugs off damp shop air and light washdown far better than painted-steel minis. A fixed anti-impact bumper pad at each end softens the direction change - it decelerates the stroke end only, it is not an adjustable air cushion.
The S code means a magnet is built into the piston, so CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke signalling without any modification. Because the MG follows the JIS mini-cylinder standard, its mounting footprint accepts standard JIS brackets and I or Y rod knuckles, which makes spare-part swaps and machine redesigns straightforward. Ports are 1/8" on every bumper MG bore, and the two-way piston seal stores lubricant for long service intervals.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X500S Is Used
Bottle-line pusher gate
A 500 mm stroke sweeps a full lane of bottles off a conveyor in one move; 402 N at 0.5 MPa easily clears a crowded 300 mm-wide row of 500 ml PET bottles.
Carton flap tucker
The long travel reaches across a 400 mm carton top to fold the far flap, with the bumper pad absorbing the snap at the end of each fast 800 mm/s cycle.
Sample tray indexer
In a lab automation line, the built-in magnet and a CMSG switch confirm each 500 mm tray advance, and the stainless barrel tolerates frequent wipe-downs.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X500S the Right Cylinder?
At 402.2 N push and 345.6 N pull at 0.5 MPa (563 N / 483.8 N at 0.7 MPa), the 32 mm bore sits between the 25 mm MG (245.3 N push at 0.5 MPa) and the 40 mm MG (628.3 N push). If your load needs more than roughly 240 N of real work - a sensible planning figure at 0.5 MPa - step up to the 40 mm bore; if 245 N is enough, the 25 mm saves space. For very high speeds or heavy loads that hammer the stroke ends, the cushioned MGC in 50 or 63 mm is the alternative. Note that a plain MG does not hold position when air is lost - the rod drifts - so add an external rod lock or a pilot check valve for suspended loads. This SKU already carries the -S magnet, so no re-order is needed to fit sensors. With a 500 mm stroke, keep side loads off the rod and use clevis (CB) or pivot (SDB) mounting to avoid rod bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA / CB / SDB) & knuckle
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 MG32X500S 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), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, and the port is 1/8". For vertical lifting, halve the push force for margin: it lifts about 20 kg safely.
Yes - the S in MG32X500S means a piston magnet is already fitted, so CMSG, DMSG or EMSG reed or electronic switches mount directly on the barrel to signal extend and retract positions. No magnet version (MG32X500) cannot take these switches.
