The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X500-100S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 500mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
The MAJ16X500-100S pairs AirTAC's smallest bore with a 500 mm run and a generous 100 mm trim window: an external stop screw lets you shorten the extend stroke anywhere within that 100 mm range once the cylinder is on the machine. It is double acting, so air drives the rod both ways, and fixed anti-impact bumper pads soak up stroke-end shock without needing an air cushion.
At 0.5 MPa the 16 mm bore pushes 100.5 N and pulls 86.4 N; in practice that is about 60 N of usable work per cycle after margin, or roughly 5 kg of vertical lift with a 2:1 factor. The riveted stainless round barrel and hard-chromed 6 mm rod shrug off washdown and damp shop air far better than painted minis, and every MA unit carries a built-in magnet, so CMSG / DMSG / EMSG switches snap on with no special order.

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.
On a small vial line the 100 mm window lets technicians dial the fill-head travel to each vial format, then lock the stop screw in place.
With about 60 N of working force the cylinder tucks light carton flaps over a conveyor reach of up to 500 mm.
A lab autoloader gates sample trays with the adjustable end stop, and CMSG switches confirm both rod positions along the long travel.
The 16 mm bore is the floor of the range; if 100.5 N at 0.5 MPa feels thin for your load, step up to MAJ20 (157 N) or MAJ25 (245.3 N) in the same compact adjustable format. Bear in mind the stop screw is a mechanical end stop only - it sets where the rod bottoms out but does not lock it, so the piston will drift if air is lost. On a 500 mm stroke with a 6 mm rod, keep side loads low and guide the load externally; FA flange, LB foot, and I / Y rod knuckles cover the mounting.
Quick checklist
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa those figures rise to 140.7 N and 120.9 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. Ports are M5x0.8, the rod thread is M6x1.0, and pressure runs 0.15-1.0 MPa (22-145 psi).
An external stop screw trims the extend stroke anywhere within the ordered 100 mm window; it is a mechanical end stop, not a mid-stroke lock, and the fixed bumper pads soften the landing at speeds of 30-800 mm/s. The 500 mm stroke is a made-to-order length, since the standard maximum for this bore is 300 mm.
