About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X60-30S
Bore 40 muscle in a riveted stainless barrel: the MAJ40X60-30S is double acting, and an external stop screw trims the extend stroke anywhere inside a 30 mm window without shims or spacer blocks. A stainless tube carries the 16 mm hard-chrome plated rod (20 um plating), while the aluminium covers are rolled onto the barrel, giving a sealed round body that tolerates washdown far better than painted-steel minis in damp or outdoor spots.
At 0.5 MPa this bore pushes 628.3 N and pulls 527.8 N, so plan on roughly 377 N of usable work force once you leave margin for friction and real loads. The piston magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight onto the barrel for end-of-stroke signalling. Fixed bumper pads soften the stroke-end impact; they decelerate only and are not an adjustable air cushion (that is the MAC family).

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 MAJ40X60-30S Is Used
Bottle-line pusher
Ejects misaligned bottles from a rinse-aid conveyor, where spray and mild detergents quickly attack painted mini-cylinder housings.
Hopper gate actuator
Drives a small ingredient-hopper slide gate, with the 30 mm stop-screw window trimming travel down to the gate's real opening.
Fixture clamp
Clamps an aluminium bracket in a machining fixture at about 377 N of working force, reach set by the external stop screw.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X60-30S the Right Cylinder?
Size down first: a bore 32 MA cylinder gives 402.2 N push at 0.5 MPa, so choose it when 377 N of working force covers the job; bore 40 is the largest MA bore, so at 628.3 N you sit at the top of the series. Keep the 16 mm rod in pure compression where possible - even at this short 60 mm stroke an offset coupling or side load will bend the rod over time. The standard magnet pairs with CMSG / DMSG / EMSG switches; mounting is FA flange or LB foot, with I and Y rod knuckles optional (the adjustable version has no SDB). Ports are 1/8" on both covers. The stop screw sets the extend limit only: if the machine must hold a position with air off, add a locking or blocking valve, because the rod can still drift.
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 MAJ40X60-30S FAQ
Double-acting thrust for this 40 mm bore: 628.3 N push at 0.5 MPa, 527.8 N pull at 0.5 MPa, 879.6 N push at 0.7 MPa, and a theoretical maximum of 128.1 kgf at 1.0 MPa. The stop screw trims the extend stroke by up to 30 mm from the ordered 60 mm stroke. Operating pressure is 0.15-1.0 MPa (22-145 psi) and speed runs 30-800 mm/s.
The magnet comes built into the piston as standard equipment, so AirTAC's CMSG, DMSG and EMSG switch range clamps onto the stainless barrel to signal extend or retract without any special-order piston. Confirm switch cable length and lead-wire type from the datasheet when specifying.
