The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X60-50S is a genuine double acting, adjustable stroke + cushion 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. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.
With a 50 mm adjustment band, the MACJ16X60-50S turns nearly the whole 60 mm travel into an on-site variable: the extend stroke can be set from 10 mm up to the full 60 mm using the external stop screw. Cushioning is variable at each end, so the 100.5 N thrust at 0.5 MPa, rising to 140.7 N at 0.7 MPa, lands softly even near 800 mm/s. Retraction pulls 86.4 N at 0.5 MPa.
This is a rolled, round-body mini cylinder: a stainless tube, hard-chrome plated 6 mm rod and aluminium covers assembled by riveting, so there is no paint to chip in damp workshops or food-area washdowns. Every unit leaves the factory with a piston magnet already fitted, and CMSG, DMSG and EMSG switches attach whenever needed. As a rule of thumb for this bore, roughly 60 N does real work at 0.5 MPa, and the theoretical 10 kgf lift figure halves to about 5 kg for safe vertical lifting.

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.

| 0.5 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.
Seals a test nipple on small cosmetic pump assemblies; 100.5 N at 0.5 MPa holds the fixture closed while air leak testing runs.
Lifts about 5 kg vertically at a 2:1 margin, comfortably handling USB connector cap grippers on a benchtop pick-and-place unit.
Pins fabric plies to a cutting table; the 50 mm window adapts to different ply heights and the stainless tube shrugs off lint and humidity.
Nothing smaller than a 16 mm bore exists in the MA family, so if 100.5 N at 0.5 MPa feels marginal for the job, move to the 20 mm frame and its 157.0 N push. Keep the working pressure between 0.15-1.0 MPa (22-145 psi) with 40 um filtered air, feed it through M5x0.8 ports, and mount with FA flange or LB foot hardware, adding an I or Y knuckle where alignment wanders. The adjustable stop defines the forward limit only - treat it as a travel setting, never as a load-holding brake, because an unpressurized cylinder still coasts.
Quick checklist
Rated output for the 16 mm bore: 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, and 20.5 kgf theoretical maximum at 1.0 MPa.
Bolt it down with an FA flange or LB foot, add an I or Y rod knuckle if alignment drifts, and plumb the M5x0.8 ports with PT, G or NPT threads at 0.15-1.0 MPa (22-145 psi).
