The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X350-10S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 350mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
A double-acting mini cylinder built for jobs where the forward stop has to land just right: an external stop screw trims the extend stroke anywhere within a 10 mm window without shimming the machine. At 0.5 MPa the 16 mm bore pushes 100.5 N and pulls 86.4 N, enough for ejecting, gating and light lifting tasks.
The riveted round body pairs a stainless-steel barrel with a hard-chrome plated 6 mm rod, so it shrugs off washdown and damp shop air far better than painted minis. A magnet ships built in, so CMSG, DMSG or EMSG switches clip on without a special-order piston. Plan on about 60 N of real work at 0.5 MPa rather than the full 100.5 N rating, leaving margin for friction and pressure drop.

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 | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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.
A 350 mm reach with a 10 mm fine-trim stop suits reagent vial indexing on a compact dosing bench, where 100.5 N at 0.5 MPa seats light vials without crushing them.
Divert envelopes or blister cards on a narrow conveyor; the chrome 6 mm rod and stainless barrel cope with dust and occasional wipe-down at the divert point.
Raise a coding head or stamp onto cartons with the extend stop set a few millimetres short, giving repeatable contact depth batch after batch.
Bore 16 is the smallest MA bore; if 100.5 N at 0.5 MPa feels tight, step up to the 20 mm bore (157 N) or the 25 mm bore (245.3 N). The 350 mm stroke is above the 300 mm standard limit for this bore, so it is made to order, and the slender 6 mm rod should be externally guided against side loads. FA flange or LB foot mounting covers the fixings. Note that the stop screw is a mechanical end stop, so on air loss the rod still drifts - it is not a mid-stroke lock.
Quick checklist
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa the figures rise to 140.7 N push and 120.9 N pull. The theoretical maximum at 1.0 MPa is 20.5 kgf. Port size is M5x0.8 and the rod thread is M6x1.0.
No. The bumper pads are fixed anti-impact pads: they soften the stroke-end hit but are not an adjustable air cushion. The 10 mm window is set by the external stop screw, which shortens the extend stroke only.
