About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-75S
Need wide latitude in where a 160 mm stroke ends? The MAJ40X160-75S lets the stop screw park the extend stroke anywhere in a 75 mm band, so one cylinder can serve several jig heights. This double-acting bore 40 mini pushes 628.3 N and pulls 527.8 N at 0.5 MPa; budget roughly 377 N for the actual task, which equates to hoisting about 32 kg vertically at a 2:1 ratio. A piston magnet is standard equipment for CMSG, DMSG or EMSG switches.
AirTAC rolls the aluminium covers onto the stainless barrel, giving a slim round body that survives damp corners of a plant where coated minis bubble and rust. The 16 mm rod is hard-chrome plated carbon steel with an M12x1.25 male thread, ports are 1/8", and fixed bumpers calm both ends of the stroke. Operating envelope: 0.15-1.0 MPa (22-145 psi), -20 to +70 C, 30-800 mm/s.

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 MAJ40X160-75S Is Used
Pallet stopper on an assembly conveyor
Raise and drop a stopper gate between assembly stations; 628.3 N at 0.5 MPa lifts the gate smartly, and the 75 mm window suits varied pallet heights.
Tub lid press on a dairy line
Press snap-on lids onto yoghurt tubs over most of the 160 mm travel, then re-trim the window per tub size without changing cylinders.
Rack elevator in a lab autoloader
Lift sample racks a set distance; about 32 kg of vertical capacity at 2:1 covers loaded racks, and the stainless body tolerates frequent wipe-down.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X160-75S the Right Cylinder?
Nothing in the MA line out-muscles bore 40; if 402.2 N at 0.5 MPa from a 32 mm bore would do, the shorter MAJ32 models cost less. Remember the adjuster is purely a mechanical end stop for extension - it is no mid-stroke brake, and the rod will creep if pressure is cut. For wide-window jobs like this one, square the FA flange or LB foot to the load and lean on I or Y knuckles when the push direction pivots.
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 MAJ40X160-75S FAQ
Push 628.3 N and pull 527.8 N at 0.5 MPa; push 879.6 N and pull 738.9 N at 0.7 MPa; 128.1 kgf theoretical maximum at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) filtered air, is proof tested at 1.5 MPa (215 psi), and moves at 30-800 mm/s.
FA flange and LB foot are the catalog mounts, and I or Y rod knuckles handle pivoting loads; the adjustable-stroke version has no SDB option. Keep side load on the 16 mm rod minimal across the 160 mm travel to protect the seals.
