About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X130-30S
Behind a riveted stainless-steel barrel just large enough to house an 8 mm rod, this double-acting MA-series mini cylinder delivers 157 N of push and 131.9 N of pull at 0.5 MPa (219.8 N / 184.7 N at 0.7 MPa). The extend stroke can be dialled down on site with an external stop screw across a 30 mm window, so one cylinder serves several station spacings. A hard-chrome plated rod shrugs off the condensation that pits painted-steel minis in bottling rooms and outdoor panels.
The magnet ships built in, so CMSG, DMSG or EMSG reed switches clip straight onto the barrel without a special piston order. Fixed anti-impact pads soften stroke-end contact - they decelerate only, while true adjustable cushioning lives in the MACJ range. At 0.5 MPa plan on roughly 94 N of usable work rather than the full 157 N rating, and expect about 8 kg of vertical lifting capability once you keep a 2:1 margin.

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 MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X130-30S Is Used
Tray pusher on a bakery line
A pneumatic pusher that nudges cookie trays onto a side lane; the 30 mm window lets one part number match lanes set anywhere from 100 to 130 mm apart.
Position confirm on an assembly cell
A CMSG switch on the barrel flags full extension of a clamp arm before the robot is allowed to release the part, with no special piston needed.
Bracket ejection from a small press die
Knocking finished brackets clear of a stamping die, where 157 N of push is ample and the chrome rod survives cutting-fluid mist.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X130-30S the Right Cylinder?
For 130 mm of travel at this force class the 20 mm bore sits between the 16 mm version (100.5 N push at 0.5 MPa) and the 25 mm version (245.3 N); step up if your mechanism needs pull above 132 N. Longer strokes on a slender rod invite side loading - guide the payload externally and stay inside the 30-800 mm/s speed band. Foot (LB) or flange (FA) mounts plus I / Y rod knuckles cover most fixtures; the stop screw is a mechanical end stop, not a lock, so a drifting piston on air loss still needs external interlocking.
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X130-30S FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa those rise to 219.8 N and 184.7 N. The theoretical ceiling at 1.0 MPa is 32.0 kgf. Run it on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) with speeds of 30-800 mm/s.
No. Every MA-series barrel carries a magnet as standard, so CMSG, DMSG and EMSG switches mount directly. FA flange, LB foot and I / Y knuckles complete the mounting options.
