The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X150-100S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 150mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
The widest trim window in the MAJ range belongs to this model: the external stop screw can pull the extend stroke back from 150 mm to as little as 50 mm, so one cylinder covers a family of end positions on a packaging or assembly fixture. It is double-acting on both faces - air extends and retracts the 6 mm rod - and delivers 100.5 N pushing and 86.4 N pulling at 0.5 MPa.
The riveted round body pairs a stainless-steel barrel with a hard-chrome plated 6 mm rod, a real edge over painted minis in damp or washdown corners. In practice, plan on roughly 60 N of usable push at 0.5 MPa, and expect the bore to lift about 5 kg vertically once you keep a 2:1 margin. Anti-impact bumper pads are fixed at each end; they soften the stop but are not an adjustable cushion. The magnet is built in as standard, so CMSG / DMSG / EMSG switches clip on without special ordering.

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.

| 0.7 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.
Trims extend travel down to 50 mm to seat flaps of varied box heights on a small carton sealer.
The 60 N working push caps lab vials and micro-plate lids without crushing the plastic.
Switches small plastic components off a mini conveyor between two chutes at selectable depths.
Bore 16 is the smallest MA tube, so step up rather than down when force runs short: the 20 mm bore pushes 157.0 N at 0.5 MPa against this model's 100.5 N. With a 100 mm trim window the stop screw is a mechanical end stop only - on air loss the piston still drifts, so do not count on it to park a load. FA flange or LB foot mounts suit static fixtures, and the 150 mm stroke on a 6 mm rod wants guided, axis-aligned loading to avoid side-load bending.
Quick checklist
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those rise to 140.7 N and 120.9 N. The theoretical ceiling at 1.0 MPa is 20.5 kgf. Running pressure is 0.15-1.0 MPa (22-145 psi) and speed is 30-800 mm/s.
An external stop screw shortens the extend stroke anywhere from 150 mm down to 50 mm. It is a hard mechanical stop, not an air cushion and not a mid-stroke lock - the fixed bumper pads only soften the hit at each end of travel.
