Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X130-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X130-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø20mm bore and 130mm 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 MACJ20X130-10S
Fine positioning is the job for the MACJ20X130-10S: its 10 mm adjust window trims the extend stroke in small steps, enough to dial in a stop or a dispense point by millimetres without changing hardware. Double-acting and cushioned at both ends, it runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air, pushing 157 N and pulling 131.9 N at 0.5 MPa, or 219.8 N push at 0.7 MPa.
Build quality matches the precision: a rolling-packed stainless-steel barrel, hard-chrome plated rod and aluminium covers, with a grease-retaining two-way piston seal. The magnet is built in as standard for CMSG / DMSG / EMSG position switches. In lift terms the 157 N push equals about 16 kg, so with a 2:1 margin it hoists roughly 8 kg vertically.

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 (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 MACJ20X130-10S Is Used
Glue nozzle micro-trim
Sets the exact stand-off of a hot-melt nozzle above carton flaps; the 10 mm window gives millimetre-level trim during changeover, and dual cushions stop the head without bounce.
Vision inspection stop
Parks electronic connectors under a camera for solder-joint checks; the built-in magnet feeding an EMSG switch confirms the part is in position before the exposure fires.
Rotary index stop pin
Drops into a dial-plate notch to lock an 8-station assembly dial; the 20 mm bore's 157 N push at 0.5 MPa resists indexing backlash at each station.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X130-10S the Right Cylinder?
For delicate positioning, the 20 mm bore gives 157 N push at 0.5 MPa - roughly 8 kg of vertical lift at half margin - while 16 mm (100.5 N) and 25 mm (245.3 N) bracket the range either side. Treat the 10 mm window as a commissioning tool: it trims the extend stroke, it does not lock the piston mid-travel, and the rod will still move if air pressure disappears. Choose FA flange or LB foot mounting, add I or Y knuckles where needed; CMSG / DMSG / EMSG switches read the built-in magnet directly.
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 MACJ20X130-10S 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 peak at 1.0 MPa is 32.0 kgf. The 130 mm extend stroke trims within a 10 mm window, with variable cushions at both ends, 30-800 mm/s speed, and 0.15-1.0 MPa (22-145 psi) supply pressure.
The rolling-packed stainless tube resists corrosion in damp cells, food-adjacent areas and outdoor cabinets where painted steel minis blister. The carbon-steel rod is hard-chrome plated to about 20 um for scratch resistance, and the two-way piston seal holds grease to keep friction low over long cycle lives.
