About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X500-20S
Framing machines and palletisers often need one cylinder that covers several product sizes, which is exactly the MAJ32X500-20S case: a 500 mm base stroke with a 20 mm on-site trim via the external stop screw. Air works both directions - 402 N out, 346 N back at 0.5 MPa.
Mounting flexibility is a quiet strength here: an FA flange pins the front cover, an LB foot bolts beneath it, and I or Y rod knuckles absorb small misalignment on swinging links. The magnet is built in as standard, so a CMSG or DMSG switch signals the trimmed end without any piston change. At 0.5 MPa the 402 N rating covers about 241 N of continuous work once a sensible margin is applied.

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 MAJ32X500-20S Is Used
Palletiser layer squaring
Before shrink-wrapping, 402 N at 0.5 MPa squares a carton layer on the pallet; the 20 mm trim absorbs slightly undersized layers.
Case-erector hold-down clamp
It pins a glue flap square while the case folds, then retracts with 346 N of pull to clear the next blank.
Fixture clamp in a welding cell
Clamping jigs beside a weld torch see spatter and heat - the stainless barrel and chrome rod hold up better there than painted units.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X500-20S the Right Cylinder?
This 32 mm bore bridges the 25 mm MAJ (about 245 N at 0.5 MPa) and the 40 mm MAJ (near 628 N), so it fits mid-weight slides and gates. Remember the adjuster is an end stop for the extend stroke, not a mid-stroke lock - if air fails, a loaded piston will still move. For the full 500 mm travel, support any side load externally to protect the 12 mm hard-chrome rod from bending. Ports on this bore are 1/8 PT, and the rod thread is M10x1.25.
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 MAJ32X500-20S FAQ
At 0.5 MPa: 402 N push and 346 N pull. At 0.7 MPa push climbs to 563 N, and the theoretical ceiling is 82 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with proof at 1.5 MPa (215 psi).
Choose FA flange, LB foot, or an I or Y rod knuckle. The external stop screw shortens the extend stroke within the ordered 20 mm window; it cannot extend travel beyond 500 mm, and it is not a position lock if air pressure is lost.
