About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X150-20S
Between the fine 10 mm and the wide 100 mm variants, the MAJ32X150-20S offers a middle 20 mm trim window on a 150 mm stroke - enough to absorb real fixture drift without giving up travel. Double-acting bore 32 output is 402.2 N push and 345.6 N pull at 0.5 MPa, or 563.0 N at 0.7 MPa.
The body is a rolled stainless-steel tube with riveted aluminium end covers and a 12 mm hard-chrome rod, compact enough for tight conveyor frames. In practice expect about 20 kg of vertical lift at 0.5 MPa with a 2:1 margin, or roughly 241 N of honest push for continuous duty. Fixed bumper pads soften both stroke ends, and the standard magnet pairs with CMSG / DMSG / EMSG switches out of the box.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAJ32X150-20S Is Used
Tray denester feed
Feeds the bottom tray from a denesting magazine on a ready-meal line, with the 20 mm window trimming feed depth to suit each tray size.
Index stop on a chain conveyor
Drops a stop blade in front of 5 kg totes at an assembly station; 402.2 N of push at 0.5 MPa squares them up against the fixture.
Spray-booth damper slide
Slides a fresh-air damper on a spray-booth duct; the stainless barrel and chrome rod shrug off overspray, with EMSG switches proving full-open.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X150-20S the Right Cylinder?
Match the bore first: 402.2 N push at 0.5 MPa sits a clear step above the MAJ25's 245.3 N and below the MAJ40's 628.3 N. The 20 mm adjuster is an extend-side end stop - never count on it to park a load against gravity when air fails; add a check valve or an external lock for that duty. FA flange and LB foot mounting plus I and Y knuckles cover most frames; over 150 mm of unsupported travel, guide the load externally to protect the 12 mm rod. The cylinder arrives sensor-ready thanks to the standard magnet.
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 MAJ32X150-20S FAQ
Double-acting, 150 mm stroke, extend stroke trimmable by 20 mm via the external stop screw. Push 402.2 N and pull 345.6 N at 0.5 MPa; push 563.0 N and pull 483.8 N at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa; 30-800 mm/s at 0.15-1.0 MPa (22-145 psi).
FA flange and LB foot are the catalogue mounts, with I and Y rod knuckles for hinged loads; the adjustable-stroke version does not take SDB or a back-cover mount code. After setting the stop screw, re-check the trim during the first runs so vibration has not walked the stroke length.
