About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X75-20SH
Fitted with a 20 mm trim window, the MAJ16X75-20SH lets you shorten the 75 mm extend stroke on site with the external stop screw, so a tooling change never forces a re-order. It is double acting: air drives the 6 mm rod out and back, fixed anti-impact pads cushion both stroke ends, and the 30-800 mm/s speed band suits quick pick-and-place cycles.
At 0.5 MPa the 16 mm bore pushes 100.5 N and pulls 86.4 N, so budget roughly 60 N for the actual job and keep the rest as margin. The riveted stainless round barrel and hard-chrome plated rod resist splashes and periodic washdown far better than painted minis, and the magnet is already built in, so CMSG, DMSG or EMSG switches clip straight on.

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 MAJ16X75-20SH Is Used
Small-part ejection
Kicks finished bushings off a micro lathe fixture; the 60 N working force and 75 mm reach clear the part without disturbing the chuck.
Lab dispenser push
Advances a reagent tray under a pipetting head, where the 20 mm trim lets the stroke be matched exactly to the tray index.
Switch-flag driver
The standard magnet and a CMSG switch give end-of-stroke confirmation for a reject gate in a small assembly cell.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X75-20SH the Right Cylinder?
Bore 16 is the smallest in the MA range; if the load needs more than about 60 N of working force at 0.5 MPa, step up to the 20 mm bore (157.0 N push) rather than leaning on higher pressure. Note the stop screw is an extend-end stop only: it is not a mid-stroke brake, so the rod can drift if air is lost mid-cycle. M5x0.8 ports keep piping small, and FA flange or LB foot brackets plus I and Y rod knuckles cover most fixings.
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 MAJ16X75-20SH 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, and the theoretical maximum is 20.5 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi) and rod speed runs 30-800 mm/s.
An external stop screw trims the extend stroke by up to 20 mm from the full 75 mm; retraction is unaffected. It is a mechanical end stop, not a load-holding lock, so on air loss the piston still drifts. Fixed bumper pads soften the stroke ends.
