About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-40S
For lift checks, a 16 mm bore pusher at 100.5 N (0.5 MPa) equals about 10 kg of raw vertical lift - halve that and parts of roughly 5 kg move with a 2:1 margin. The MAJ16X120-40S is double-acting with an extend stroke trimmed up to 40 mm by an external stop screw, housed in a riveted stainless round barrel that resists washdown splash far better than painted or plain aluminium minis.
Pull force at 0.5 MPa is 86.4 N and push climbs to 140.7 N at 0.7 MPa. It cycles 30-800 mm/s on a 0.15-1.0 MPa (22-145 psi) air feed. The 6 mm rod is hard-chrome plated carbon steel, the magnet comes built in for CMSG / DMSG / EMSG switches, and fixed anti-impact pads soften both stroke ends without adding a cushion function.

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 MAJ16X120-40S Is Used
Tray divider positioning
Sets dividers in a small-parts tray at any depth within the 40 mm window; the 100.5 N push at 0.5 MPa slides plastic dividers with ease.
Optics bench hold-down
Gently clamps lens holders on a laboratory bench - about 60 N of usable push protects delicate glass, and the stainless body wipes clean after spills.
Connector seat verification
Presses ribbon-cable connectors home in test fixtures; a CMSG switch on the built-in magnet confirms full seat before the electrical test starts.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X120-40S the Right Cylinder?
Need more muscle than 100.5 N? The 20 mm bore MAJ pushes 157 N at 0.5 MPa, while this 16 mm stays the lightest and most compact choice. With 120 mm of travel on a 6 mm rod, keep side loads off the rod or guide them externally - thin rods bend before bearings complain. Bolt it down via FA flange or LB foot, fit an I or Y knuckle if the load pivots, and treat the 40 mm adjuster purely as a mechanical stop, never a drift-proof clamp.
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 MAJ16X120-40S FAQ
Design around 100.5 N push and 86.4 N pull at 0.5 MPa; push rises to 140.7 N at 0.7 MPa and the theoretical ceiling for this bore is 20.5 kgf at 1.0 MPa. The air supply must stay within 0.15-1.0 MPa (22-145 psi) and be filtered to 40 um.
No - every MA-series cylinder ships with the magnet built in, so CMSG, DMSG or EMSG switches clip straight onto the stainless barrel. The trim screw offers up to 40 mm of extend adjustment, but it holds position only mechanically at the end of stroke and will not lock the rod against drifting.
