The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X75-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 75mm 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.
Tight tolerance is the story here: a 10 mm window lets you fine-trim the 75 mm extend stroke with the external stop screw, useful when a fixture position is settled but needs a millimetre or two of final adjustment. It is double-acting with a variable cushion at both ends, rated 100.5 N push and 86.4 N pull at 0.5 MPa across a 0.15-1.0 MPa (22-145 psi) supply.
Construction follows the MA pattern - a riveted stainless round barrel, aluminium covers and a hard-chrome plated 6 mm rod that resists corrosion in damp or lightly washed corners of the plant. The magnet comes built in; CMSG, DMSG and EMSG switches bolt on as needed. For sizing, treat about 60 N as your working push at 0.5 MPa, which supports roughly 5 kg of vertical lift with a 2:1 margin.

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.
Setting an exact clamp pad position on a machining fixture, where the 10 mm window covers final tweak without a cylinder change.
Advancing a part into a gauging cradle on a quality bench with a repeatable, cushioned 75 mm approach every cycle.
Raising small aluminium fittings between pallet trays - about 5 kg, comfortably inside the halved vertical-lift margin for this bore.
If 100.5 N at 0.5 MPa leaves no headroom, step up to the 20 mm bore (157.0 N push) or 25 mm bore (245.3 N) in the same family. The 75 mm stroke is well inside the 300 mm standard limit for bore 16, so no made-to-order barrel is involved. Choose FA flange or LB foot mounting, fit I or Y knuckles where the load swivels, and remember the stop screw only sets the extend end position - it cannot lock the rod against drift when air is lost.
Quick checklist
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa expect 140.7 N push and 120.9 N pull. Theoretical peak at 1.0 MPa is 20.5 kgf. Bore is 16 mm with a 6 mm rod (M6x1.0 thread) and M5x0.8 port; air supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
The variable air cushion is adjustable at both ends, and the -10 stop screw trims the extend stroke across a 10 mm window. The adjuster sets position only; on air loss the piston drifts freely, so do not rely on it as a brake.
