About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X80-50S
Where a profile body will not fit, this riveted round MAJ32X80-50S slots a 50 mm trim window into an 80 mm stroke. Thrust stays true to the 32 mm bore: 402.2 N forward and 345.6 N back at 0.5 MPa, an 82 kgf force class in a compact package.
Aluminium-alloy covers and a stainless block are rolled onto the stainless barrel, giving a short, sealed body that resists the damp and washdown which defeat painted minis. Size real work at roughly 241 N of usable force - 60 percent of the 0.5 MPa push - and add I or Y rod knuckles where the tooling needs float. The piston magnet for CMSG, DMSG or EMSG sensing ships as standard.

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 MAJ32X80-50S Is Used
Die ejector
Ejecting sintered bronze bushings from a small press die: 402 N at 0.5 MPa clears the part, and the 50 mm trim shortens the return cycle.
Terminal insert press
Seating crimp terminals into connector housings on a light assembly cell, where the 82 kgf force class of the 32 mm bore is more than enough.
Guard gate latch
Latching a machine guard gate closed before spindle start, with an FA flange on the frame and a Y knuckle linking the gate arm.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X80-50S the Right Cylinder?
Three sizes bracket this one at 0.5 MPa: 245.3 N from a 25 mm bore, 402.2 N here, 628.3 N from a 40 mm bore. If your cycle later grows toward the bore's 500 mm maximum stroke, add an external guide - the compact round barrel is not a side-load stiffener.
The trim stop fixes where the rod ends its travel; it does not secure the piston against drift, so a gravity load needs another means of restraint when air is lost. FA flange, LB foot, I and Y knuckles cover the mounting, and the piston magnet supports CMSG, DMSG and EMSG switches without any special order.
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 MAJ32X80-50S FAQ
Figures to size with: 402.2 N push and 345.6 N pull at 0.5 MPa; 563.0 N push and 483.8 N pull at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. The operating band is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure and 30-800 mm/s speed.
Choose an FA flange for face mounting or an LB foot for base mounting, and add I or Y rod knuckles when the tooling needs a little float. The adjustable-stroke version has no SDB option or back-cover code, and the piston magnet for CMSG, DMSG or EMSG switches is included as standard.
