Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-75S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-75S 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 MACJ50X160-75S
Among the MACJ trim options, the -75S carries the widest window: the extend stroke can be set anywhere from 85 to 160 mm at the machine. The design is double-acting throughout, variably cushioned at both ends.
Structurally you get the MA signature: a riveted stainless round barrel, aluminium-alloy covers and a 16 mm hard-chrome rod that copes with damp, dusty or outdoor air. Every cylinder includes the position magnet, so CMSG, DMSG or EMSG switches mount directly on the barrel. Feed it 40 um-filtered air at 0.15-1.0 MPa (22-145 psi) and cycle between 30 and 800 mm/s.

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 MACJ50X160-75S Is Used
Fixture clamp across a welding cell
Clamping steel brackets into a jig; the wide 75 mm trim adapts clamp height when the jig family changes, and cushioned landings protect the weldment.
Quick-change press depth on an assembly press
Setting punch depth per SKU from the same cylinder across a 75 mm range, trimming changeover time on mixed-model assembly lines.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-75S the Right Cylinder?
Cross-check against neighbours: bore 40 pushes 628.3 N at 0.5 MPa for lighter tooling, bore 63 pushes 1557.9 N for heavier fixtures. The 75 mm window suits lines with frequent changeovers where one cylinder must serve several stroke positions. FA flange and LB foot are the mounting bases, with I and Y knuckles for rod-end joints. The stop screw fixes only the extend end stop and is not a load-holding brake, so specify a locking valve wherever gravity could back-drive the load. At 160 mm of stroke, external guides should carry any side load instead of 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 MACJ50X160-75S FAQ
Bore 50 mm with a 16 mm chrome-plated rod, 1/4 in ports and an M14x1.5 male rod thread. Stroke 160 mm adjustable across a 75 mm window (85 to 160 mm), 30-800 mm/s, 0.15-1.0 MPa (22-145 psi).
Choose the FA flange for face mounting on a machine plate or the LB foot for base mounting; I and Y rod knuckles suit swinging links. The stop screw sets the extend end stop and is not a mid-stroke lock, so the rod still moves if air pressure is lost. Cushion needles sit in both covers for end-of-stroke tuning.
