About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X500-40S
Built for long, slim runs, the MAJ16X500-40S is a double-acting round-body mini cylinder with a 500 mm stroke that an external stop screw can shorten by up to 40 mm on site. At 0.5 MPa it pushes with 100.5 N, so after derating you can plan on roughly 60 N of real work - about 5 kg lifted vertically with a 2:1 margin.
The stainless-steel barrel and hard-chrome plated 6 mm rod shrug off the damp and washdown that eat painted-steel minis, and the fixed anti-impact pad softens the stroke end without needing an air cushion. A magnet ships built in, so CMSG, DMSG or EMSG switches clip on straight away.

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 MAJ16X500-40S Is Used
Packaging line gate pusher
Slides small cartons or divert gates along a 500 mm path at up to 800 mm/s, with the 40 mm trim letting you match different carton depths.
Light-panel lift assist
Raises inspection covers or light acrylic panels, staying inside the roughly 5 kg vertical lift this bore supports at 0.5 MPa on a 2:1 margin.
Long-reach eject on assembly rigs
Kicks finished small components off a fixture bed after the cycle, its stainless barrel coping with coolant mist around machine tools.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X500-40S the Right Cylinder?
Bore 16 is the smallest in the MAJ line, so the only way is up: if 100.5 N at 0.5 MPa feels thin, the bore 20 version delivers 157.0 N from the same family. The M5x0.8 ports suit the 4 mm tubing runs typical of mini circuits. The 40 mm window only shortens the extend stroke - it is a mechanical end position only, never a mid-stroke lock, so the rod can drift if air is lost.
Mount with an FA flange or LB foot and add I or Y rod knuckles where the coupling wants a pivot. At 500 mm the slender 6 mm rod is side-load sensitive, so guide the load externally and keep thrust in line with the bore axis.
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 MAJ16X500-40S FAQ
At 0.5 MPa it pushes 100.5 N and pulls 86.4 N; at 0.7 MPa the figures rise to 140.7 N push and 120.9 N pull, with a theoretical maximum of 20.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) and speed spans 30-800 mm/s.
An external stop screw trims the extend stroke anywhere within 40 mm of the full 500 mm, so one cylinder can serve several product depths. The stop sets the end position only - it will not hold the load if supply air drops.
