About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X450-50S
Half a metre of stroke from a Dia 16 round body: the MAJ16X450-50S gives you 450 mm of reach and a 50 mm on-site trim band for dialling in the extend end position. Double-acting throughout, it develops 100.5 N pushing at 0.5 MPa - budget roughly 60 N for the actual job and it will run all day. Vertically, that is about 5 kg of lift once you keep a 2:1 margin.
The stainless barrel with its hard-chromed rod is the reason to pick this over a painted mini in damp or dusty corners. Bore 16 normally stops at 300 mm, so 450 mm is a made-to-order stroke; the anti-impact bumpers are fixed at both ends, and the standard magnet accepts CMSG / DMSG / EMSG switches for end-of-travel detection. The aluminium covers are rolled onto the tube, giving a slim, sealed package with no protruding hardware.

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 MAJ16X450-50S Is Used
Height adjuster on a packaging inspection station
Wind the 50 mm stop screw to match camera height when changeover swaps carton sizes on the same line.
Kick-off pin on an assembly pallet line
About 60 N of practical push retracts locating pins as pallets pass, and the stainless body shrugs off chip coolant mist.
Home position actuator on a test rig
Pair the standard magnet with CMSG switches so the PLC confirms the trimmed extend position every cycle.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X450-50S the Right Cylinder?
Against neighbours in the range, MAJ20 pushes 157 N and MAJ25 245.3 N at 0.5 MPa; if 100.5 N (86.4 N on retract) covers the load, this bore 16 unit costs less in air and space. Remember the 50 mm window only pulls the extend stroke shorter - it cannot add travel, and with air off the rod is free to move, so support any held part separately.
For a 450 mm run choose LB foot mounts for horizontal duty or an FA flange where the cylinder hangs; I and Y knuckles suit pivot joints. Keep side loads off the 6 mm rod over this length - a simple guide rail pays for itself in seal life. Air connection is 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 MAJ16X450-50S FAQ
At 0.5 MPa: 100.5 N push and 86.4 N pull. At 0.7 MPa: 140.7 N push and 120.9 N pull. Theoretical peak is 20.5 kgf at 1.0 MPa. The port is M5x0.8 and the rod thread is M6x1.0 male; supply air filtered to 40 um at 0.15-1.0 MPa (22-145 psi) and cycle anywhere in the 30-800 mm/s band.
The pads at each stroke end are fixed anti-impact bumpers - they absorb the piston's arrival and cut end-of-stroke noise, but they cannot be tuned like an adjustable cushion (that capability lives in the AirTAC MAC family). They decelerate the piston only; they never act as a brake against external loads.
