About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X65-20S
Because the barrel is stainless and the 12 mm rod is hard-chrome plated to 20 um, mild corrosive washdown is a non-event for the MAJ32X65-20S compared with coated mini cylinders. The double-acting unit delivers 402 N push at 0.5 MPa (345.6 N pull) and 563 N at 0.7 MPa, and its external stop screw trims the extend stroke anywhere within the ordered 20 mm window - a mid-range window that suits variant-to-variant product changes.
It holds a trimmed end position only; under air failure the rod is free to move, so fixture design must not count on the stop as a lock. CMSG / DMSG / EMSG switches drop onto the stainless barrel out of the box thanks to the standard piston magnet. If the 20 mm window feels tight for repeated changeovers, the same bore comes with 50 mm and 100 mm windows; if the cushioning matters more than trimming, the MACJ adds adjustable air cushions in the same force class.

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 MAJ32X65-20S Is Used
Drill jig part ejection
A kick stroke that pushes finished bushings out of a drilling jig, with the 20 mm window set so the ejector clears the bushing without knocking the fixture.
Packaging slide gate
Diverting product between two packing lanes - the stainless round body handles the humid, washable zone near the filler.
Spray valve actuator
Opening a glue or coating spray valve with 402 N of push at 0.5 MPa, sized so the valve stays seated against line pressure.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X65-20S the Right Cylinder?
The 32 mm bore sits between the MAJ25 at 245 N push (0.5 MPa) and the MAJ40 at 628 N - pick 32 when your clamped load lands near the 241 N derated work figure. Ports are 1/8" in PT (blank), G or NPT; rod thread M10x1.25. Choose FA flange, LB foot, or an I / Y knuckle for the rod end. At 65 mm stroke keep thrust axial or guide the load sideways, since round-body mini cylinders tolerate little rod bending.
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 MAJ32X65-20S FAQ
At 0.5 MPa: 402.2 N push, 345.6 N pull. At 0.7 MPa: 563.0 N push, 483.8 N pull. Theoretical maximum: 82 kgf at 1.0 MPa. Plan real work below about 241 N for a reliable margin, run it on 0.15-1.0 MPa (22-145 psi) air, and expect 30-800 mm/s travel.
The stainless tube is rolling-packed with riveted aluminium-alloy covers and a stainless block into a sealed, compact body - no tie rods to loosen, no extrusion slot to collect swarf. Fixed anti-impact bumper pads soften both stroke ends (they decelerate only; adjustable cushioning belongs to the MAC family), and the rod carries a hard 20 um chrome plating over carbon steel.
