The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X35-20S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 35mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Double acting on both ends of its travel, the MAJ16X35-20S pairs a 16 mm bore with a 35 mm stroke and a 20 mm extend-trim window set by an external stop screw. Push output at 0.5 MPa is 100.5 N - enough for diverting, marking or light press tasks at the very small end of automation.
Round stainless barrel plus a 20 um hard-chrome rod mean the cylinder survives coolant mist and outdoor splash far better than painted mini bodies, and the riveted construction keeps the footprint tight. In practice, reserve about 60 N of the 100.5 N rating for the actual job; that also translates to lifting roughly 5 kg vertically once a 2:1 margin is applied. CMSG / DMSG / EMSG switches mount on the built-in magnet with no special-order 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. |
| ×35 | 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.
Kicks lightweight blister packs from one lane to another; the 20 mm trim absorbs lane-spacing changes.
Presses a transfer label onto a curved cosmetic bottle with about 60 N of real force at 0.5 MPa.
Stops a light fixture carrier at the indexed angle; a CMSG switch confirms the stop has been reached.
Compare before you buy: the 20 mm MAJ bore delivers 157.0 N push at 0.5 MPa, a solid step up from this 16 mm model. The 20 mm window is wide enough to re-stop the extend stroke between fixture revisions without a reorder. Note the adjuster is a mechanical end stop, not a mid-stroke lock - with no air the rod still moves. FA flange, LB foot, and I / Y rod knuckles cover the common mounting patterns.
Quick checklist
Push at 0.5 MPa is 100.5 N and pull is 86.4 N; at 0.7 MPa expect 140.7 N push and 120.9 N pull, with 20.5 kgf theoretical peak at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), air filtered to 40 um, speed 30-800 mm/s, port M5x0.8.
No - every MA-series cylinder leaves the factory with a built-in magnet, so CMSG / DMSG / EMSG switches clamp on directly. The heterogeneous piston seal also stores grease, stretching the interval between maintenance stops.
