About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X20-10S
Short moves with a settable end position are what the MAJ32X20-10S does best: double-acting, 20 mm base stroke, and a stop screw that trims the extend stroke across a 10 mm window. Bore 32 generates 402.2 N at 0.5 MPa pushing and 345.6 N pulling, so even this stubby actuator plans for about 241 N of real working force at 60 percent of rating - ample for clamping or ejecting small parts.
Construction stays true to the MA family: a stainless round barrel rolled onto aluminium-alloy covers, a 12 mm hard-chrome plated rod, and fixed anti-impact bumper pads that decelerate the stroke ends without any cushion tuning. The magnet is built in as standard, so CMSG, DMSG or EMSG switches mount without a special piston. Media is filtered air (40 um) at 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speeds 30-800 mm/s, ports 1/8".

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 MAJ32X20-10S Is Used
Mold knock-out for plastic caps
A short 20 mm punch drops finished caps off the core after molding; the 10 mm trim lets the molder raise the ejection point for delicate thin-wall tooling.
PCB hold-down on a test fixture
The rod presses a circuit board onto pogo-pin contacts with about 241 N of planned working force, holding it flat through a full functional test.
Vial indexing on a lab filler
A 10 to 20 mm nudge advances one vial per stroke into the filling nest, and the magnet-driven CMSG switch confirms each index to the PLC.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X20-10S the Right Cylinder?
For a 20 mm stroke pushing 402.2 N, compare the 25 mm bore at 245.3 N when the load is lighter and the 40 mm bore at 628.3 N when it is not - bore choice costs nothing extra at order time. The -10 window means the extend stroke can be set anywhere from about 10 mm up to the full 20 mm; it never extends beyond 20 mm. The stop screw is an end stop, not a brake, so a drifting load under air loss needs a separate locking valve. FA flange and LB foot mountings plus I or Y knuckles cover most fixture layouts, and the standard magnet suits CMSG or DMSG sensing in tight envelopes.
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 MAJ32X20-10S FAQ
Bore 32 pushes 402.2 N and pulls 345.6 N at 0.5 MPa. At 0.7 MPa expect 563 N push and 483.8 N pull. Maximum theoretical force at 1.0 MPa is 82 kgf. Operating pressure spans 0.15-1.0 MPa (22-145 psi); proof pressure is 1.5 MPa (215 psi).
The anti-impact pads are fixed - they soften stroke-end deceleration but are not an adjustable air cushion, which is the MACJ family's job. For sensing, every MAJ ships with a standard built-in magnet, so CMSG, DMSG and EMSG switches snap onto the barrel with no special-order piston.
