About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X300-50S
Long travel, short trimming: the MAJ32X300-50S runs a 300 mm stroke whose extend length is adjustable across a full 50 mm window by an external screw, all while pushing 402.2 N at 0.5 MPa in a double-acting circuit that cycles at 30-800 mm/s.
Washdown lines and humid workshops favour the stainless round barrel and 20 um hard-chrome rod, which resist the corrosion that flakes painted mini cylinders. Rated up to 82.0 kgf theoretical force at 1.0 MPa, but budget about 20 kg of vertical lifting (half the 41 kg gravity equivalent) to keep duty cycles honest.

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 MAJ32X300-50S Is Used
Dosing gate actuation
Drives a dosing gate on a chemical metering skid, the 50 mm window matching the required valve travel per recipe.
AGV dock latch release
Releases the dock gate latch on an AGV loading station, with the extend stroke matched to the latch travel.
CNC part offload
Sweeps finished parts off a CNC chuck into a collection chute, adjustable to the chuck-to-chute distance.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X300-50S the Right Cylinder?
Sizing check: a bore 25 mini gives 245.3 N at 0.5 MPa, this bore 32 gives 402.2 N, and stepping up to bore 40 buys 628.3 N - pick the first that clears your demand with headroom. The external adjuster is an extend-side end stop, not a mid-stroke brake; loads will sag if supply air is lost.
Over a 300 mm stroke even small misalignment multiplies, so keep lateral forces on dedicated guide rails instead of the rod. FA flange and LB foot brackets, I/Y rod knuckles, and the factory-fitted magnet complete the spec.
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 MAJ32X300-50S FAQ
Use 402.2 N push and 345.6 N pull at 0.5 MPa, or 563.0 N and 483.8 N at 0.7 MPa; the 1.0 MPa theoretical ceiling is 82.0 kgf. Air supply is 0.15-1.0 MPa (22-145 psi) and the 12 mm rod carries an M10x1.25 male thread.
FA flange and LB foot brackets plus I and Y rod knuckles cover the usual fixings (no SDB on adjustable models), and the built-in magnet is standard, so CMSG, DMSG or EMSG switches can be added at any stroke position right away.
