About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X90-50S
A wide -50 window dominates this model's spec: the external stop screw trims the 90 mm extend stroke by up to 50 mm on site, a generous turn-down range for machines that run multiple product sizes. Thrust is 402.2 N at 0.5 MPa and 563.0 N at 0.7 MPa, with 345.6 N of return force at the lower pressure, all double-acting between 0.15-1.0 MPa (22-145 psi).
Construction follows the MA recipe: a stainless-steel barrel rolled tight against aluminium covers, a hard-chrome carbon-steel rod, and fixed anti-impact bumpers at each end of the stroke. Sensing needs no special piston because the magnet is standard equipment, pairing directly with CMSG, DMSG and EMSG switches. In practice, budget around 241 N of the 402.2 N rating for useful work at 0.5 MPa - a margin that keeps output predictable through the cylinder's service life.

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 MAJ32X90-50S Is Used
Multi-size carton stop on a case packer
One cylinder serves short and tall cartons alike because the 50 mm window shifts the stop position between product recipes.
Trim press for plastic sprue removal
Cuts sprues off moulded fittings with 563 N at 0.7 MPa behind a small blade holder, cycling between 30 and 800 mm/s.
Z-axis lift for a vision inspection camera
Raises a compact camera head between inspection positions; the 402.2 N push lifts about a 20 kg gantry vertically once a 2:1 margin is applied.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X90-50S the Right Cylinder?
A quick check against neighbours: the 25 mm MAJ tops out at 245.3 N push at 0.5 MPa while the 40 mm version starts at 628.3 N, leaving this 32 mm unit ideal for mid-range loads. When a gravity load must stay put on air failure, remember the adjuster acts only as an extend-side stop - the rod is free to be back-driven, so specify external locking. FA flange and LB foot mounts, plus I and Y rod knuckles, suit most frames, and the standard magnet keeps CMSG / DMSG / EMSG readout simple.
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 MAJ32X90-50S FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa the figures are 563.0 N and 483.8 N, with 82 kgf as the theoretical peak at 1.0 MPa. The 32 mm bore uses a 12 mm rod threaded M10x1.25, a 1/8" port, 0.15-1.0 MPa (22-145 psi) supply and 30-800 mm/s speed.
The -50 suffix buys a 50 mm window: within it, the external stop screw sets any shorter extend stroke on the 90 mm cylinder without swapping parts. Adjustment is mechanical - fixed bumper pads handle stroke-end impact, but the stop neither cushions like a MACJ nor holds a load if air pressure is lost.
