About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X450-30S
For a 450 mm reach in a tight envelope, the MAJ16X450-30S pairs a Dia 16 stainless round barrel with a hard-chromed 6 mm rod, double-acting and riveted into a compact body. An external stop screw trims the extend stroke anywhere inside the ordered 30 mm window, so one cylinder can serve several end positions without swapping hardware. At 0.5 MPa it pushes 100.5 N, which is about 60 N of practical work once you plan at 60% of rating.
The 450 mm stroke is beyond the 300 mm standard limit for bore 16, so this unit is built to order. Fixed anti-impact bumper pads soften the stroke ends (they decelerate only, they are not an adjustable air cushion), the magnet is fitted as standard for CMSG / DMSG / EMSG switches, and the rolled stainless body shrugs off washdown better than painted-steel minis. Halving the push figure, it lifts about 5 kg vertically with a 2:1 margin.

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 MAJ16X450-30S Is Used
Reject gate on a bottling line
A 30 mm trim window lets one cylinder deflect or release bottles at two positions along a 450 mm approach without re-plumbing.
Wire-spool transfer arm
About 60 N of practical push at 0.5 MPa is enough to index light spools between winding stations on the long 450 mm stroke.
Sample elevator in a lab feeder
The stainless barrel tolerates the frequent wipe-downs a lab carousel cleaner needs while lifting roughly 5 kg vertically.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X450-30S the Right Cylinder?
Bore 16 sits at the light end of the MA range: 100.5 N push and 86.4 N pull at 0.5 MPa. If the load needs more, MAJ20 gives 157 N push and MAJ25 gives 245.3 N in the same round-body family. The 30 mm window here only shortens the extend stroke; the stop is a mechanical end stop, not a mid-stroke lock, so the rod can still drift if air is lost.
Over a 450 mm stroke the 6 mm rod is exposed to side loads - guide the load externally rather than cantilevering it off the rod. Mount with FA flange or LB foot, add I or Y rod knuckles if the axis needs play, and pick PT, G or NPT ports; bore 16 takes M5x0.8.
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 MAJ16X450-30S FAQ
Double-acting 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. The air port is M5x0.8 and the male rod thread is M6x1.0. It runs on 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, at 30-800 mm/s.
An external stop screw shortens the extend stroke anywhere within the 30 mm window ordered, set by hand on the machine. It is a mechanical end stop for the extend direction only - it does not lengthen the stroke and it is not a load-holding brake, so the rod will still drift if air pressure is lost. Fixed bumper pads cushion both stroke ends.
