About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X450-40S
With 40 mm of on-site trim, the MAJ32X450-40S gives the widest setup window in this series: set the extend stop anywhere within the last 40 mm of the 450 mm stroke using the external screw. Force class matches the bore 32 row - 402 N push, 346 N pull at 0.5 MPa and 563 N push at 0.7 MPa, with up to 82 kgf theoretically at 1.0 MPa.
A rolled stainless barrel, hard-chrome plated rod and aluminium covers handle damp and mildly corrosive environments better than painted minis. Keep in mind the screw is a mechanical end stop only: on air loss the piston still drifts, so add an external clamp wherever a load must be held.

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 MAJ32X450-40S Is Used
Can-line lane gate
Switches cans between lanes on a beverage filler; the 40 mm window lets changeover staff re-set the extend stop for each can size in minutes.
Lift table latch
Releases a latch on a lift-assist table; the near 20 kg vertical lift equivalent (2:1 margin on 41 kg) matches counterweight loads around that scale.
Router plunge stop
Sets the plunge depth stop on a compact CNC router; the 40 mm trim covers common tool-length changes, while linear ways carry the side load.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X450-40S the Right Cylinder?
Force ladder at 0.5 MPa: 25 mm gives 245 N, this 32 mm bore gives 402 N, and 40 mm gives 628 N - step up a size if your lift needs more than the roughly 241 N working figure. Vertically the 402 N rating equals about 41 kg of lift, or near 20 kg with a 2:1 margin.
Long strokes benefit from guide rails to keep rod bending low. FA flange and LB foot mountings are available, with I or Y knuckles for pivoting loads; the built-in magnet means CMSG / DMSG / EMSG position sensing is a bolt-on, not an option to order.
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 MAJ32X450-40S FAQ
At 0.5 MPa the cylinder pushes 402 N and pulls 346 N. At 0.7 MPa it reaches 563 N push and 484 N pull, and the theoretical peak at 1.0 MPa is 82 kgf. Pressure envelope is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi); speed 30-800 mm/s.
FA flange or LB foot brackets carry the body, and I or Y rod knuckles suit pivoting loads. The extend stroke is trimmed by an external stop screw anywhere within the 40 mm window; ports are 1/8" on the 32 mm bore and the rod thread is M10x1.25.
