Airtac MG Stainless Steel Mini Air Cylinder MG32X40S
The AirTAC Airtac MG Stainless Steel Mini Air Cylinder MG32X40S is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.

About the Airtac MG Stainless Steel Mini Air Cylinder MG32X40S
With a 32 mm bore pushing 402.2 N at 0.5 MPa (563 N at 0.7 MPa), this MG32X40S is a double acting JIS round-body mini cylinder built for compact clamping and short-stroke positioning. Air drives the rod both ways, a 12 mm hard-chrome plated rod transmits the force, and a fixed anti-impact bumper pad at each stroke end softens the direction change. The 1/8" ports, PT thread and 0.15-1.0 MPa (22-145 psi) operating band suit standard plant air.
The barrel is SUS304 stainless steel riveted onto the covers, so the body shrugs off washdown and damp shop air far better than painted-steel minis, and the JIS mounting footprint drops into standard mini-cylinder brackets and knuckles. Because the magnet is built in, CMSG, DMSG or EMSG switches clamp straight onto the tube for end-of-stroke detection. As a planning figure, keep real work to roughly 240 N (about 24 kg vertical lift) at 0.5 MPa rather than the full 402.2 N rating.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG32X40S Is Used
Small fixture clamping
The 402.2 N push at 0.5 MPa secures aluminium brackets in CNC drilling fixtures, with the 40 mm stroke clearing part loading quickly.
Sensed part ejection
Built-in magnet plus a CMSG switch confirms the 40 mm eject stroke on a packaging line reject chute, cycling at 30-800 mm/s.
Lab press positioning
A short 40 mm advance presses sample caps in a test rig, where the SUS304 barrel tolerates frequent wipe-down between batches.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG32X40S the Right Cylinder?
At 402.2 N push and 345.6 N pull (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): step down when force is marginal, step up for heavier clamps. The 40 mm stroke is short, so keep side loads off the 12 mm rod and guide the workpiece externally. Note that a plain MG drifts when air is lost - the bumpers only soften the stroke end, so add a pilot check valve or external rod lock if the load must stay put. Mounting options are LB foot, FA flange, CB clevis or SDB pivot, with I and Y rod knuckles; the S in this SKU means the magnet for CMSG / DMSG / EMSG sensors is already fitted.

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 MG32X40S 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 is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, speed 30-800 mm/s, and the 1/8" ports take PT thread as standard.
Yes. The S in the model code means a piston magnet is built in, so CMSG, DMSG or EMSG reed/hall switches mount directly on the stainless barrel for end-of-stroke signalling. Keep in mind the fixed bumper pads only soften the stroke end - they are not an adjustable cushion and do not hold a load if air pressure drops.
