About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X60-40S
For packaging machinery that needs short, hard pushes, the MAJ40X60-40S packs a 40 mm bore into a rolled stainless tube as comfortable beside a rinse tank as inside a dry case-packer. The external stop screw shortens the extend stroke by up to 40 mm on site, so tuning reach to a new carton size means a screwdriver, not a re-order, and the riveted aluminium covers keep the round body slim under machine guarding.
This bore pushes 628.3 N at 0.5 MPa, which lifts about 32 kg vertically once you take a 2:1 margin - match that against a filled jar, a small fixture or a gate leaf. Fixed anti-impact bumper pads soften arrival at both stroke ends, and the standard piston magnet drives CMSG / DMSG / EMSG switches for pack-confirmation signals.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MAJ40X60-40S Is Used
Carton eject
Kicks filled cartons off a checkweigher conveyor; the built-in magnet feeds a CMSG switch that confirms full retract each cycle.
Lid press
Snaps lids onto tubs with about 32 kg of vertical press margin at 0.5 MPa, final reach dialed in with the 40 mm stop screw.
Fill-level probe lift
Raises and lowers a fill-level sensor arm beside a syrup filler, where the stainless tube and chrome rod shrug off sticky overspray.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X60-40S the Right Cylinder?
Against a bore 32 cylinder (402.2 N push at 0.5 MPa), this 40 mm model gives roughly 55% more force in a body barely larger, and no bigger MA bore exists - this is the top of the range. Count the vertical case too: halving the 64 kgf theoretical lift leaves a comfortable 32 kg for real jars or fixtures. Both covers take 1/8" ports, and FA flange or LB foot mounts plus I and Y knuckles cover most frame designs. If the process must hold a retracted or mid position during a power loss, remember the adjuster is a travel stop, not a brake - the piston can move once pressure drops.
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 MAJ40X60-40S FAQ
At 0.5 MPa the 40 mm piston gives 628.3 N push and 527.8 N pull; at 0.7 MPa push rises to 879.6 N. The theoretical ceiling at 1.0 MPa is 128.1 kgf. For sizing, treat roughly 377 N at 0.5 MPa as the realistic working force after margin.
The MAJ pairs a stainless-steel round barrel with a 20 um hard-chrome plated carbon-steel rod and rolled aluminium covers, so splash, humidity and mild detergents that ruin painted minis are not a concern. Operating temperature spans -20 to +70 C, the media is air filtered to 40 um, and pressure runs 0.15-1.0 MPa (22-145 psi).
