Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-50S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-50S is a genuine double acting, double rod, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 160mm stroke, 1/4" 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.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-50S
Need stroke tuning rather than fixed travel? The MACJ50X160-50S shortens its 160 mm extend stroke anywhere across a 50 mm window, 110 to 160 mm, using an external stop screw.
The stainless round barrel, riveted aluminium-alloy covers and hard-chrome 16 mm rod make it a natural for food-side and outdoor stations where painted minis corrode. Supply is simple: 40 um filtered air, 0.15-1.0 MPa (22-145 psi), -20 to +70 C, cycled between 30 and 800 mm/s. The magnet comes built in, so CMSG, DMSG or EMSG switches need 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.
Theoretical Output Force (Ø50mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 kgf |
MAJ / MACJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-50S Is Used
Lid press on a dairy filler
Pressing lids home on rinse trays in a washdown zone; the stainless barrel and chrome rod take the daily hose-down that swells or rusts painted minis.
Rotary index lock on a dial table
Extending a locking pin into the index plate; the 50 mm window tunes engagement depth per fixture without changing the cylinder.
Tote pusher on a sortation conveyor
Kicking totes onto a cross-belt sorter; both-end cushions tame the push at speeds up to 800 mm/s so the tote does not bounce off the belt.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-50S the Right Cylinder?
Mount via the FA flange or LB foot, with I and Y rod knuckles covering linkages. The trim screw sets end-of-stroke position only and will not lock the rod if supply pressure drops. With 160 mm of travel, support any side load on external guides rather than the rod.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-50S FAQ
Bore 50 mm, stroke 160 mm adjustable over a 50 mm window (110 to 160 mm). Pressure band 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Each end carries a variable cushion you set by needle valve, absorbing load momentum as the piston lands. That lets you run the cycle toward the 800 mm/s ceiling or move heavier tooling without hammering the covers, extending the life of the two-way heterogeneous piston seals.
