The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X350-30S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø32mm bore and 350mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
A 30 mm trim window makes the MAJ32X350-30S easy to dial in: fit the cylinder, run it once, then turn the external stop screw until the extend stroke lands exactly where the machine needs it - anywhere from 320 mm to the full 350 mm. Double-acting, it develops 402.2 N of push and 345.6 N of pull at 0.5 MPa.
The build is a riveted round body: stainless tube rolled onto aluminium-alloy covers, with a 20 um hard-chrome plated 12 mm rod that shrugs off washdown and damp plant air far better than painted minis. Theoretical vertical lift at 0.5 MPa is about 41 kgf; planning for roughly 20 kg with a 2:1 margin keeps the cylinder well inside its comfort zone. The piston magnet is standard, so CMSG, DMSG or EMSG switches drop on without a special-order piston.

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.

| ×350 | Stroke length in mm. |
| -30 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |

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.
Sets timber or aluminium extrusion length on a cut-off saw; the 30 mm window absorbs blade-kerf and fence adjustments without shimming.
Sorts cartons at a belt junction; 345.6 N of pull retracts the blade sharply for 30-800 mm/s cycling under PLC control.
Advances bakery trays onto a conveyor in 350 mm pitches; the magnet-fed DMSG switch counts each index for the line controller.
Downsize to the MA25 (245.3 N push at 0.5 MPa) when the task is lighter, or upsize to the MA40 (628.3 N) when it grows. With 350 mm of stroke, external guiding is worth specifying - long rods magnify any side load. FA flange or LB foot mounting, I / Y knuckles as accessories, and a standard magnet for CMSG / DMSG / EMSG switches round out the spec. The 30 mm adjuster is purely an extend-stroke end limit; it cannot clamp a load in place if the air supply drops, so add a locking valve where holding matters.
Quick checklist
At 0.5 MPa: 402.2 N push and 345.6 N pull. At 0.7 MPa: 563.0 N push and 483.8 N pull. Maximum theoretical output at 1.0 MPa is 82 kgf. Air supply is 0.15-1.0 MPa (22-145 psi), speed spans 30-800 mm/s, the port is 1/8" and the male rod thread is M10x1.25. PT is the standard thread; G and NPT are order options.
Yes - the magnet is a standard part of the MA piston, so CMSG, DMSG and EMSG reed or electronic switches snap onto the barrel with no special-order piston and no surcharge. Because the body is a riveted round tube rather than a tie-rod stack, the switches sit directly on the stainless barrel.
