The AirTAC Airtac MA Mini Cylinders MA32X100SU is a genuine double acting standard round-body mini air cylinder with a Ø32mm bore and 100mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Pushing 402.2 N and pulling 345.6 N at 0.5 MPa (22-145 psi), this 32 mm MA brings real clamp force to the stainless round-body format, rising to 563.0 N at 0.7 MPa. Double acting with fixed anti-impact bumper pads, it covers the 100 mm stroke at 30-800 mm/s.
Because the barrel is high-precision stainless steel and the 12 mm rod is hard-chrome plated carbon steel, the cylinder keeps moving in damp plants and outdoor machinery where painted minis corrode. The magnet is a standard fit, so CMSG, DMSG and EMSG switches report position from day one. For sizing, hold the working force near 241 N at 0.5 MPa, or figure about 20 kg of vertical lift once a 2:1 margin is applied.

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.

| 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.
Lifts a case-packing guard gate of about 20 kg in a small palletising cell, matching the vertical-lift figure.
Presses nylon bushings into punched control-panel housings, drawing on up to 563.0 N at 0.7 MPa.
Drives a sample ram in an environmental test rig, where condensing humidity demands the stainless barrel.
This sits between the 245.3 N MA25 and the 628.3 N MA40, so confirm your force budget before ordering; the 82 kgf theoretical peak at 1.0 MPa is not a working figure. A 100 mm stroke with a 12 mm rod will bend under meaningful side load, so guide the payload on linear rails or a cam and keep the rod in pure thrust. Mounting is flexible: the U flat-end cover for direct bolting, FA flange, LB foot or SDB pivot to suit the frame, plus I and Y knuckles on the rod. Remember the MA is a through-motion cylinder - when air leaves, the piston moves freely, so carry a suspended load only with a rod lock or check valve in the circuit.
Quick checklist
Figures for the 32 mm bore: 402.2 N push and 345.6 N pull at 0.5 MPa; 563.0 N push and 483.8 N pull at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Ports are 1/8", the rod is 12 mm with an M10x1.25 male thread, and the 100 mm stroke is standard (bores in this series run to 500 mm).
No - the pads absorb the last of the travel but there is no adjustment screw as on the MAC range, so at higher speeds keep the external stop solid. The 1.5 MPa (215 psi) proof pressure and 0.15-1.0 MPa (22-145 psi) working band give ordinary shop-air headroom.
