Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø20mm bore and 160mm stroke, 1/8" 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.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-10S
Fine-tuning is the whole point of the MACJ20X160-10S: a 10 mm window on a 160 mm stroke lets operators creep the extend position in small steps for processes where a few millimetres decide pass or scrap. This 20 mm bore double-acting mini pushes 157 N at 0.5 MPa (220 N at 0.7 MPa) and cushions at both ends, so dialled-in stops stay gentle.
Construction follows the proven MA recipe: a stainless-steel round barrel, a hard-chrome plated rod and aluminium covers rolled in place for a sealed body. Because the magnet comes standard, CMSG, DMSG and EMSG switches read position with no special piston. Derating matters on accurate set-ups - work to about 94 N of true force at 0.5 MPa, which is roughly an 8 kg vertical lift at half the rating.

Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-10S Is Used
Glue nozzle fine set
Trims a hot-glue nozzle height on a case tucker by millimetres so beads land on the flap, not the board.
Vision-station micro-set
Holds a 2D camera bracket at the exact focal distance above blister packs on an inspection line.
Dial-table stop pin
Sets the index stop on a small rotary assembly table; cushioned landings keep the pin from ringing.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-10S the Right Cylinder?
At 157 N push, bore 20 more than doubles the 16 mm figure of 100.5 N but sits below the 25 mm bore's 245.3 N at 0.5 MPa; pick by part weight rather than by price. The 10 mm trimmer is a mechanical end stop only - if air fails, the rod still moves - so never rely on it to park a load. Match FA flange or LB foot hardware, order PT, G or NPT threads, and keep side loads off the 8 mm rod on the long 160 mm stroke to avoid bending.
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 MACJ20X160-10S FAQ
Push is 157 N and pull 131.9 N at 0.5 MPa; at 0.7 MPa push reaches 219.8 N, and the theoretical ceiling is 32 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi) of 40 um filtered air, run 30-800 mm/s, and use the 10 mm window to trim the extend stroke below 160 mm.
Both work together: the screw sets where the extend stroke ends, and the variable cushion decelerates the piston into that stop, so re-trimming does not reintroduce impact. LB foot or FA flange mounts fix the body, and the standard magnet feeds CMSG, DMSG or EMSG switches.
