About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X225-20S
The 20 mm adjust window on this bore 32 ram absorbs tolerance stack-up: order MAJ32X225-20S with a 225 mm stroke and shorten the extend stop anywhere inside 20 mm after installation. Force is genuine mid-band output, 402.2 N push and 345.6 N pull at 0.5 MPa, 563.0 N push at 0.7 MPa, 82 kgf theoretical maximum. That push equates to roughly 41 kg of vertical lift, or about 20 kg once a 2:1 margin is kept.
Mechanically it is a compact, riveted round-body unit: stainless barrel, aluminium covers, and a 12 mm rod hard-chrome plated to 20 um that shrugs off rust in damp or outdoor corners. Anti-impact bumpers are fixed at both stroke ends; they soften impact but are not adjustable air cushions. Every MA-series piston carries its magnet as standard, so CMSG / DMSG / EMSG switches need no special order, and the cylinder runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

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 MAJ32X225-20S Is Used
Tube-frame weld fixture clamp
Clamp bicycle or furniture tube frames at each weld station; 563.0 N push at 0.7 MPa holds joints closed, and the 20 mm window absorbs frame tolerance stack-up.
Bottling lane divert gate
Push bottles between lanes on a filling line; the built-in magnet pairs with CMSG / DMSG / EMSG switches to confirm gate position before the filler starts.
Hinge-plate pin setter
Press hinge pins into door plates on a small assembly bench; the stop screw sets a repeatable extend limit within the 20 mm window so every pin seats to the same depth.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X225-20S the Right Cylinder?
Against its neighbours: 25 mm bore pushes 245.3 N and 40 mm bore 628.3 N at 0.5 MPa, placing this 32 mm model at 402.2 N in between. The external screw sets only where the rod stops on extend; with pressure gone the piston is free to move, so add a block or brake wherever the load must stay put.
Match FA flange or LB foot to the frame, add I or Y knuckles for linkage loads, and note that at 225 mm the rod should work against a guided, not cantilevered, load.
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 MAJ32X225-20S FAQ
Push 402.2 N and pull 345.6 N at 0.5 MPa; push 563.0 N and pull 483.8 N at 0.7 MPa; theoretical maximum 82 kgf at 1.0 MPa. Pressure range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s, stroke trimmable by up to 20 mm with the stop screw.
The high-precision barrel is stainless steel and the 12 mm piston rod is hard-chrome plated to 20 um, so mild corrosion, splash and outdoor exposure are handled far better than by painted-steel or plain-aluminium mini cylinders. The aluminium covers are riveted onto the tube, keeping the round body sealed and compact.
