The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X60-20S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 60mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Fine-positioning tasks rarely need the full 60 mm, and the 20 mm adjustment window on the MAJ16X60-20S lets a technician dial the extend stroke down on the machine - an external stop screw does the work in minutes. Output sits at the light end of the range: 100.5 N push and 86.4 N pull at 0.5 MPa, rising to 140.7 N at 0.7 MPa; keep the working figure near 60 N for a healthy service margin.
Two build details earn their keep: the hard-chrome plated 6 mm rod slides in a stainless round barrel that resists washdown and mild corrosion, and fixed bumper pads decelerate the stroke end so light parts are not jolted. The magnet is standard, so EMSG switch mounting needs no special piston.

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. |
| ×60 | Stroke length in mm. |
| -20 | 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.
The 60 N practical force at 0.5 MPa is enough to fold the minor flaps on small cartons at slow-to-moderate packaging speeds.
Trim the extend stroke 20 mm so a coated nozzle kisses a test surface without crushing it on a lab dispensing rig.
A stainless barrel survives outdoor weather on a control-cabinet latching mechanism, with a DMSG switch confirming latch status.
If 100.5 N at 0.5 MPa is marginal for your clamp or lifter, the bore 20 MAJ at 157 N is the natural step up; if it is generous, note that bore 16 is already the smallest MAJ size. Vertical lifts: at 0.5 MPa the 100.5 N rating corresponds to about 10 kg, so with a 2:1 margin plan on lifting roughly 5 kg.
The 20 mm window fits nests whose stop position shifts by a couple of centimetres between SKUs. Choose FA flange or LB foot, add I or Y rod knuckles where needed, and remember the adjuster is an end stop - it does not hold position mid-stroke if the air drops.
Quick checklist
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa it delivers 140.7 N push and 120.9 N pull, with a theoretical peak of 20.5 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), speed runs 30-800 mm/s, and the extend stroke is trimmable by 20 mm via the external stop screw.
For the 16 mm bore: M5x0.8 air ports, an M6x1.0 male rod thread on the 6 mm rod, FA flange or LB foot mounting plus I and Y rod knuckles, all inside the compact riveted round body. Fixed anti-impact bumper pads come with every unit; tunable air cushioning belongs to the MACJ variant instead.
