The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X150-10S is a genuine double acting, adjustable stroke + cushion 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. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.
A fine 10 mm trim window on a 150 mm extend stroke makes this 16 mm MACJ the pick when final positioning must be nudged on the machine rather than re-engineered. It is double-acting with variable cushioning at both ends, rated 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s. At 0.5 MPa expect 100.5 N of push, about 60 N of dependable working force once you keep a sensible margin, and 140.7 N at 0.7 MPa.
The rolling-packed body pairs a stainless barrel with a hard-chrome carbon-steel rod, so light corrosion and washdown are non-issues where painted minis would flake. The magnet comes standard, feeding CMSG, DMSG or EMSG switches out of the box.

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.
Seating small connectors into housings on an electronics assembly cell, using the 10 mm window to dial in exact seating depth after tooling swaps.
Driving a lightweight print head on a packaging date coder, where the stainless rod resists ink and cleaner residue and the trim screw squares up the print gap.
Raising microplates about 5 kg-equivalent in a screening station, with the 60 N working margin keeping lifts smooth at 0.5 MPa.
The 16 mm bore is the smallest in the MA range, so if 100.5 N at 0.5 MPa is still surplus, trim the supply pressure down instead of hunting for a smaller cylinder. The next size up, 20 mm, delivers 157.0 N push at 0.5 MPa. Treat the -10 adjuster as a mechanical extend limit only; it cannot hold position when air is lost, so park loads against a hard stop or a valved circuit. FA flange and LB foot mounts, plus I and Y knuckles, cover the fixing options.
Quick checklist
Push at 0.5 MPa is 100.5 N and pull is 86.4 N; at 0.7 MPa push is 140.7 N and pull 120.9 N. The theoretical maximum is 20.5 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, double-acting with a 10 mm adjustable extend window.
Yes. The round barrel is high-precision stainless steel and the rod is carbon steel with a 20 um hard-chrome plating, so splash zones, food washdown and outdoor cells will not rust it the way painted or plain aluminium minis corrode. The riveted aluminium covers keep the seal integrity intact over years of cycling.
