About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X100-40S
With a 402 N push at 0.5 MPa (346 N retract), the MAJ32X100-40S sits in the mid-force range of the MAJ family while keeping a 100 mm base stroke. The -40 suffix lets maintenance crews wind the external stop screw to shorten extend travel by up to 40 mm right on the machine, no disassembly needed. Double-acting air drives both directions and fixed anti-impact pads cushion each end.
Lift-wise, this bore can raise about 41 kg vertically at full 0.5 MPa push; halving for a 2:1 margin leaves a comfortable 20 kg part per station. The riveted stainless round barrel and 12 mm hard-chrome rod take splashing and wipe-down far better than painted minis, and every cylinder carries its magnet from the factory for CMSG, DMSG or EMSG switches.

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 MAJ32X100-40S Is Used
Label head press
A pressure-sensitive label applicator presses its roller head onto 1 L detergent bottles; trimming the extend stroke by up to 40 mm matches label placement heights without re-fixturing.
Small parts elevator
On a pick-and-place gantry, the cylinder raises a 15 kg aluminium tray between assembly levels - the 41 kg theoretical lift at 0.5 MPa leaves a 2:1 safety margin.
Web tension idler roll
A converting machine uses the adjustable stop to press an idler roller against a moving film web, applying near 241 N of practical force without crushing the material.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X100-40S the Right Cylinder?
Compare before you buy: the MAJ25 bore offers 245 N at 0.5 MPa for lighter clamps, while the MAJ40 bore reaches 628 N for heavier presses. This 32 mm model is the balance point for lifts around 20 kg with margin. Keep in mind the stop screw marks a position but does not lock the rod against air loss - the piston will settle if pressure drops, so use a locking valve where holding is critical. FA flange and LB foot plates plus I/Y knuckles bolt to most jig plates, and the 1/8" port accepts standard fittings.
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 MAJ32X100-40S FAQ
Key figures: 402.2 N push and 345.6 N pull at 0.5 MPa; 563 N push and 483.8 N pull at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Base stroke is 100 mm, trimmed up to 40 mm via the stop screw, speed 30-800 mm/s, working pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
No. The stop screw is a hard mechanical end position with fixed anti-impact bumper pads that only soften the arrival - it is not an adjustable air cushion, which is the MAC family's job. It sets position only; on air loss the piston can drift, so it should never be relied on as a load-holding brake.
