About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-30S
Thirty millimeters of post-install trim is the headline: maintenance can dial the 160 mm extend stroke down anywhere in that 30 mm window with the external stop screw, so one cylinder serves several fixture heights. Push is 628 N at 0.5 MPa and 880 N at 0.7 MPa on a 0.15-1.0 MPa (22-145 psi) supply; for cycle duty plan on roughly 377 N of usable force.
AirTAC rolls the aluminum covers onto a stainless round barrel to form a sealed, compact riveted body, and the 20 um hard-chrome rod resists washdown splash. Every unit carries its magnet as standard, so CMSG / DMSG / EMSG switches drop on with no special piston order.

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 MAJ40X160-30S Is Used
Bushing seating press
Seats light bushings into pump housings on a benchtop arbor press; the 30 mm trim absorbs casting height tolerance.
Belt scraper holder
Presses a scraper blade against the return strand of a conveyor, with blade contact pressure set through the adjustable stop.
Palletizer squaring arm
Sweeps the leading carton layer square on a semi-automatic palletizer before strapping begins.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-30S the Right Cylinder?
Bore 40 sits a class above 32 (628 N versus 402 N push at 0.5 MPa), so drop down only if your task needs under about 240 N. With 160 mm of stroke, route lateral forces into slide bushings or a Y knuckle rather than the 16 mm rod. Order FA or LB mounting and the M12x1.25 male rod thread as PT, G or NPT; the air port is 1/8". Treat the trim screw as a repeatable seating stop, never a mid-stroke clamp: lost air pressure still lets the rod settle under gravity.
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 MAJ40X160-30S FAQ
Use 628 N push and 528 N pull at 0.5 MPa, or 880 N push and 739 N pull at 0.7 MPa; the theoretical maximum is 128.1 kgf at 1.0 MPa. Stay within 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s with air filtered to 40 um.
Choose an FA flange or LB foot for the body, and add I or Y rod knuckles where the tool must pivot. The adjustable-stroke version does not offer SDB or a back-cover code. Air ports are 1/8" and the male rod thread is M12x1.25, ordered as PT, G or NPT.
