The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X125-30S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 125mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Built on AirTAC's riveted round barrel, the MAJ16X125-30S is a 16 mm bore mini cylinder, double acting, with a 125 mm stroke and a 30 mm adjustable window: an external stop screw trims the extend stroke anywhere in that range on site. At 0.5 MPa it pushes 100.5 N and pulls 86.4 N, enough for light clamping and small-part handling. Air supply runs 0.15-1.0 MPa (22-145 psi) and rod speed 30-800 mm/s.
A stainless-steel barrel with a 20 um hard-chrome plated 6 mm rod shrugs off washdown and mild corrosion, a real edge over painted mini cylinders in damp food or outdoor corners. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight on. In practice, plan on roughly 60 N of usable push at 0.5 MPa, and the bore will lift about 5 kg vertically with a 2:1 margin.

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.

|---|---|
| 16 | Bore size in mm. |
| ×125 | 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). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
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.
Swings a small reject gate on a pharma vial line; the 125 mm stroke and 30 mm trim dial in the swing without shimming.
Drives a 6 mm locating pin into aluminium brackets on a light machining fixture; 100.5 N at 0.5 MPa covers the press fit.
Knocks small trays off a stainless conveyor in a dairy washdown zone where the chrome rod and steel barrel resist corrosion.
This is the smallest MA bore, so size upward when forces climb: the 20 mm bore delivers 157.0 N and the 25 mm bore 245.3 N at 0.5 MPa. Port is M5x0.8 and the rod thread is M6x1.0. Mount with FA flange or LB foot, or add an I or Y rod knuckle. Remember the adjuster is a mechanical end stop for the extend stroke only - it will not hold a load if air pressure drops.
Quick checklist
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa push rises to 140.7 N and pull to 120.9 N. The theoretical maximum at 1.0 MPa is about 20.5 kgf.
Yes. Every MA-series cylinder ships with the magnet built in as standard, so CMSG, DMSG and EMSG switches mount directly on the barrel without a special-order piston.
