About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-75S
With a 75 mm adjustment window, the MAJ16X120-75S lets a technician dial the extend stroke anywhere between 45 and 120 mm using the external stop screw - no shims, no cylinder swap. It is a double-acting, round-body mini cylinder: air drives the piston both ways, and fixed anti-impact bumper pads soften each end of travel. At 0.5 MPa the Dia 16 bore pushes 100.5 N and pulls 86.4 N.
Plan on roughly 60 N of usable work at 0.5 MPa (about 0.6 of the push rating), or think of it as lifting about 5 kg vertically with a 2:1 margin. The stainless-steel barrel pairs with a 6 mm hard-chrome plated rod, so the body resists mild corrosion in damp or washdown-prone corners that would pit painted minis. A magnet is built in as standard, so CMSG, DMSG or EMSG switches mount straight on the barrel.

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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MAJ16X120-75S Is Used
Small-part divert gate
A lightweight flap on a 120 mm conveyor lane that kicks small cartons or blister packs into a reject chute; 100.5 N at 0.5 MPa easily moves a 200 g part, and the 45-120 mm trim dials the throw.
Sample pusher in a lab autosampler
Slides sample trays or vial racks a set distance; the wide 75 mm window lets one cylinder serve trays of different heights after a simple turn of the stop screw.
Label press-on roller
Presses a self-adhesive label onto a flat cosmetic bottle; the roughly 60 N working force is plenty for a tacky label, and the stainless barrel suits a rinse-friendly bench.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-75S the Right Cylinder?
Bore 16 is the smallest in the MA range, so if 100.5 N at 0.5 MPa feels thin, step up to a 20 mm bore (157 N) or a 25 mm bore (245.3 N) at the same pressure. Keep in mind the stop screw only sets the extend end position - it is not a mid-stroke lock, so the rod will drift if air is lost.
Mount with an FA flange or LB foot, add an I or Y rod knuckle if the load pivots (the adjustable version has no SDB option), and note the 6 mm rod on a 120 mm stroke wants external guiding whenever side load is present. The built-in magnet works with CMSG / DMSG / EMSG switches for position feedback.
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 MAJ16X120-75S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa push rises to 140.7 N. The theoretical maximum for the Dia 16 bore is about 20.5 kgf at 1.0 MPa. Working pressure spans 0.15-1.0 MPa (22-145 psi) and rod speed runs 30-800 mm/s.
Built in as standard. Every MAJ ships with the piston magnet fitted, so CMSG, DMSG and EMSG reed or Hall-effect switches mount directly on the stainless barrel for end-of-stroke or position signalling - no special-order piston needed.
