The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X100-30S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 100mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
A 16 mm bore mini cylinder with a tunable extend stroke, the MAJ16X100-30S is double-acting and carries a stainless round barrel, a hard-chrome plated 6 mm carbon-steel rod and aluminium covers rolled on for a sealed, riveted body. An external stop screw sets any extend stroke from 70 to 100 mm on site, and at 0.5 MPa the bore delivers 100.5 N on extend and 86.4 N on retract.
For planning, expect about 60 N of usable work at 0.5 MPa rather than the full 100.5 N rating - roughly 5 kg of vertical lift once you take a 2:1 margin. Fixed bumper pads soften the stroke ends (they decelerate only - this is not an air-cushion cylinder), the slim riveted body suits tight machines, and the built-in magnet accepts CMSG / DMSG / EMSG switches with no special-order piston. Operating range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.

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.
| MAJ | Standard round-body mini cylinder (adjustable-stroke). |
|---|---|
| 16 | Bore size in mm. |
| ×100 | 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.
Stepping microplate carriers one position along a 100 mm rail in compact lab automation, where 100.5 N at 0.5 MPa is ample for light carriers.
Tipping lids on tuck-in carton machines beside heat-seal heads, with the stainless barrel wiping clean in damp packaging areas.
Ejecting dowel-pinned parts from a benchtop drilling jig using about 60 N of practical work force at 0.5 MPa.
Bore 16 is the smallest MA size, so compare upward before ordering: MAJ20 pushes 157.0 N and MAJ25 245.3 N at 0.5 MPa. The -30 window trims the extend stroke down to 70-100 mm, but the screw is a stroke end stop only - if air is lost the rod still drifts, so never rely on it to hold a load in place. Mount with an FA flange or LB foot, add I or Y rod knuckles at the rod end, and pick up position feedback from the standard magnet.
Quick checklist
At 0.5 MPa: 100.5 N extend and 86.4 N retract. At 0.7 MPa: 140.7 N extend and 120.9 N retract. Theoretical maximum is 20.5 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi), speed is 30-800 mm/s and the port is M5x0.8.
The barrel is a rolled stainless tube paired with a hard-chrome plated carbon-steel rod and aluminium covers riveted into a sealed round body, so it shrugs off washdown and damp shop air that pit painted minis. Fixed bumper pads cushion the stroke ends; they decelerate only and are not adjustable air cushions.
