The AirTAC Airtac MA Mini Cylinders MA32X50SU is a genuine double acting standard round-body mini air cylinder with a Ø32mm bore and 50mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Short-stroke clamping is where the MA32X50SU earns its keep: a 32 mm stainless round barrel, double acting with fixed bumper pads, driving 402.2 N forward and 345.6 N back at 0.5 MPa over just 50 mm. The riveted body shrugs off mild corrosion in damp shops where painted minis peel.
Treat 241 N as the practical working push at 0.5 MPa; vertically that is about 20 kg of lift at a 2:1 margin. Air supply from 0.15-1.0 MPa (22-145 psi) drives it at 30-800 mm/s. Because the magnet is built in, a CMSG or DMSG switch snaps onto the barrel to confirm clamp-closed. The bumper pads trim impact at each stroke end but are not an adjustable cushion - variable deceleration remains the MAC family's job.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.
Clamps an aluminium bracket into a machining jig; 402 N at 0.5 MPa holds the part against side cutting forces with margin to spare.
Kicks finished parts out of a shallow forming die each cycle; the 50 mm stroke matches tight die pockets and 30-800 mm/s speed keeps the pace.
Latches food-tray lids on a washdown line, where the stainless barrel outlasts painted-steel bodies exposed to daily hose-downs.
Between the 25 mm bore at 245.3 N push and the 40 mm bore at 628.3 N (both at 0.5 MPa), this 32 mm sits mid-range; if the clamp must deliver close to 241 N of real work, step up. The U flat-end back cover suits fixed mounting, with FA flange, LB foot or SDB pivot brackets as options. With only 50 mm of stroke there is little rod overhang, so side-load worries stay minimal. Remember the piston drifts when air is lost, so pilot a check valve if the clamp must stay shut.
Quick checklist
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa expect 563.0 N push and 483.8 N pull; theoretical maximum force is 82 kgf at 1.0 MPa. Port size is 1/8", rod thread M10x1.25, rod diameter 12 mm.
It presents a flat, drilled face that bolts straight onto a fixed machine frame, skipping extra pivot brackets; FA flange, LB foot or SDB mounting can be added later if the layout changes.
