Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-20S
The AirTAC MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-20S 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 MACJ50X160-20S
Bore 50, stroke 160, 20 mm of trim: this MACJ covers jobs where the stop moves occasionally between two or three positions. It is double-acting with a variable air cushion at both ends, built on a riveted stainless round barrel with a hard-chromed 16 mm rod, and it pushes 981 N at 0.5 MPa.
Supply air at 0.15-1.0 MPa (22-145 psi), run 30-800 mm/s, and clip a CMSG, DMSG or EMSG switch onto the barrel - the magnet is already inside as standard.

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 MACJ50X160-20S Is Used
Fixture clamp on a CNC pallet cell
Move the stop within 20 mm when switching between two fixture heights, keeping one cylinder for the whole cell.
Bottle crate depalletizer push
981 N at 0.5 MPa sweeps layers of PET bottles onto a takeaway conveyor, with cushions easing each sweep.
Sorter gate diverter
Fast cycling across 30-800 mm/s plus the built-in magnet and an EMSG switch gives confirmed divert feedback at each gate.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X160-20S the Right Cylinder?
Push force at 0.5 MPa runs 628 N for a 40 mm bore and 1558 N for a 63 mm bore, so this 50 mm unit at 981 N is the middle choice for eject and clamp duty. The 20 mm adjust window gives room for tooling changes without reordering; the stop positions the rod but will not hold it against drift when air drops. FA flange or LB foot mounts plus I and Y rod knuckles suit most frames, and a 160 mm stroke should see minimal side load or external guides.
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 MACJ50X160-20S FAQ
Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed spans 30-800 mm/s.
FA flange and LB foot are the catalog mounts, with I and Y rod knuckles available for pivoting tool points; the adjustable-stroke version does not use SDB or back-cover codes. The 1/4" ports suit typical plant air, pressure spans 0.15-1.0 MPa (22-145 psi), and the standard magnet accepts CMSG, DMSG or EMSG switches.
