Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-30S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-30S 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 MACJ50X160-30S
Double-acting and adjustable, this MACJ puts a 50 mm stainless barrel to work on a 160 mm stroke you can trim at the machine. Air drives the rod both ways and a variable cushion softens each landing. At 0.5 MPa the bore pushes 981.3 N and pulls 880.8 N; at 0.7 MPa that climbs to 1373.8 N, with a theoretical ceiling of 200.1 kgf. The external stop screw shortens the extend stroke anywhere inside a 30 mm window, from 130 to 160 mm, without swapping hardware.
Construction gives it a real edge in damp or washdown spots: the high-precision stainless round barrel, riveted aluminium-alloy covers and 20 um hard-chrome rod shrug off corrosion that kills painted minis. The magnet ships built in, so CMSG, DMSG or EMSG switches clip on straight away. Run it on 40 um-filtered air at 0.15-1.0 MPa (22-145 psi), -20 to +70 C, at 30-800 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 MACJ50X160-30S Is Used
Capping head on a bottling line
Pressing caps home through a 160 mm guarded reach; the 30 mm window lets the same cylinder serve several bottle heights without re-plumbing air lines.
Coolant-side scrap gate
Sweeping aluminium offcuts off a CNC discharge chute, where the stainless barrel and chrome rod resist the coolant mist that rusts painted mini bodies.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-30S the Right Cylinder?
A 160 mm stroke sees side loads in most fixtures, so guide the load on rails or a guide rod and let this cylinder supply pure thrust. FA flange and LB foot mountings bolt to the covers; I and Y rod knuckles suit swinging linkages. The trim screw only sets the extend end stop and does not lock the rod when air drops, so add a locking valve where a drifting load would matter.
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 MACJ50X160-30S FAQ
At 0.5 MPa the 50 mm bore pushes 981.3 N and pulls 880.8 N. The theoretical maximum at 1.0 MPa is 200.1 kgf. Stroke runs 160 mm with a 30 mm adjustable window, cushioned at both ends, rated 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s.
Yes. The piston magnet is fitted as standard on every MACJ, so CMSG, DMSG or EMSG switches mount on the stainless barrel straight from the box, with no special piston or factory delay. The port thread is 1/4 in and the male rod thread is M14x1.5.
