About the Airtac MGC Stainless Steel Mini Cylinder MGC32X25S
The AirTAC MGC32X25S is a double acting, JIS-standard round-body mini cylinder with a 32 mm bore and a short 25 mm stroke, built with a variable air cushion at both ends. Unlike the bumper-style MG, the cushion needles let you dial in smooth deceleration near each end of travel, so this cylinder tolerates higher piston speeds and heavier moving loads without hammering the covers. Push force is 402.2 N and pull force is 345.6 N at 0.5 MPa (72 psi), rising to 563 N push at 0.7 MPa (101 psi), with a theoretical maximum of 82 kgf at 1.0 MPa.
Construction follows the MG family recipe: a SUS304 stainless barrel with covers and stainless block riveted and rolled onto it, plus a hard-chrome plated (20 um) 12 mm carbon-steel rod with a male M10x1.25 thread. The two-way piston seal also stores lubricant for long service life. The fitted magnet (the S in the code) accepts CMSG, DMSG or EMSG switches for end-of-stroke detection. Air supply should be filtered to 40 um, operating pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), temperature range is -20 to +70 C, and speed range is 30-800 mm/s. Ports are 1/8". Note that the cushion only decelerates the stroke end; it is not a lock or brake, so use an external rod lock or pilot check valve if the load must be held on air loss.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC32X25S Is Used
High-cycle pick and place
The variable air cushion absorbs end-of-stroke shock at speeds up to 800 mm/s, letting a compact 32 mm bore (402.2 N push at 0.5 MPa) cycle small parts quickly without cover damage, while the -S magnet feeds position signals to the PLC.
Light pressing and forming
With 563 N push at 0.7 MPa (101 psi), the MGC32X25S suits small press-fit, staking and marking stations where cushioned deceleration protects tooling as the rod reaches the work.
Conveyor gating and diverting
A 25 mm stroke is ideal for short pusher and stopper gates; the adjustable cushion stops the moving load smoothly at both ends, and LB foot or FA flange mounting adapts to the conveyor frame.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC32X25S the Right Cylinder?
At 32 mm bore, the MGC32X25S sits mid-range in the cushioned MGC line: it delivers 402.2 N push at 0.5 MPa (72 psi), roughly 41 kgf, so a safe working load is about 24 kg using the 0.6 rule of thumb, or roughly 12 kg for vertical lifting. Step down to bore 20 (157.0 N push) or 25 (245.3 N) if force is generous, or up to bore 40 (628.3 N) for more muscle; bores 50 (981.3 N) and 63 (1557.9 N) top the range. If your application runs slowly with light loads and you do not need adjustable deceleration, the bumper-type MG covers bores 20-40 as the no-cushion alternative. Mounting is FA flange or LB foot, with I and Y rod knuckles available, and the -S magnet enables CMSG/DMSG/EMSG sensing. The 25 mm stroke is well within the 500 mm standard range for this bore (non-standard strokes to 800 mm are made to order), but keep side loads off the rod on any stroke length to protect the bearings.

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 and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGC Stainless Steel Mini Cylinder MGC32X25S FAQ
At 0.5 MPa (72 psi) it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa (101 psi) push rises to 563 N and pull to 483.8 N. The theoretical maximum is 82 kgf at 1.0 MPa. Applying a 0.6 safety factor to the 0.5 MPa push force gives a safe working load of about 24 kg, or roughly 12 kg for vertical lifting.
The cushion is adjustable at both stroke ends: turn the needle valves to meter exhaust and decelerate the piston smoothly, which is why the MGC handles higher speeds and heavier moving loads than the bumper-type MG. It is a deceleration feature only, not a lock or brake, so the MGC32X25S will not hold position on air loss; add an external rod lock or pilot check valve for a held load. The stainless SUS304 barrel and hard-chrome 12 mm rod suit harsh or washdown-adjacent environments, and the fitted magnet accepts CMSG, DMSG or EMSG switches.
