About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X500-50S
Air at both ports makes the MAJ32X500-50S double-acting, and the -50 code means the extend stroke can be shortened by up to 50 mm with the external stop screw - turn it in, lock it, and the rod stops earlier on every cycle. Push force at 0.5 MPa is 402 N against 346 N on the retract side, enough to lift about 20 kg vertically once you take a 2:1 margin on the 41 kgf theoretical figure.
For mounting, the FA flange bolts the barrel face to a machine plate while the LB foot set seats it on a base; I and Y knuckles take up rod-end misalignment on pivoting levers. Inside, the 12 mm hard-chrome rod runs in a stainless tube that resists the condensation found in bottling halls and outdoor conveyors. The fixed bumper pads simply cushion stroke ends - no cushion-adjustment screws here, that is MACJ territory.

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 MAJ32X500-50S Is Used
Stack-height correction in palletizer cells
The 50 mm window absorbs stack tolerance so each layer lands level; 402 N at 0.5 MPa settles carton columns without crushing them.
Tooling stop adjustment on CNC transfer rails
A setup technician shortens the extend stroke in seconds when a fixture changes, avoiding a cylinder swap mid-shift.
Reject chute diverter on beverage lines
A DMSG switch wired to the trimmed stop point confirms the diverter is fully home before the filler releases bottles.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X500-50S the Right Cylinder?
Compare forces at 0.5 MPa: the smaller MAJ25 gives 245 N and the larger MAJ40 gives 628 N, so this bore 32 lands between them at 402 N - strong for compact grippers and gates yet lighter on air than the 40 mm option. The stop screw only limits extension; it never locks the rod in place, so a dropped air line still lets the piston move - fit a brake or vented check if holding matters. At 500 mm of travel, keep side loads off the 12 mm rod with external guides, and run 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air. The standard magnet pairs with CMSG, DMSG and EMSG switches for end-of-stroke signals.
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 MAJ32X500-50S FAQ
At 0.5 MPa: 402 N extend, 346 N retract. At 0.7 MPa: 563 N extend, 484 N retract. Theoretical maximum is 82 kgf at 1.0 MPa. The port is 1/8 in, the rod thread M10x1.25, the rod 12 mm, and the 500 mm stroke trims by up to 50 mm via the stop screw.
A rolled stainless barrel with a hard-chrome 12 mm rod stands up to washdown splash, humidity and outdoor dust that quickly rust painted mini cylinders, while the riveted aluminium covers keep the body compact. Since the piston magnet is standard, CMSG, DMSG or EMSG switches click straight onto the tube with no special-order piston.
