About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X300-20S
With a 20 mm trim window over a 300 mm stroke, the MAJ16X300-20S gives commissioning engineers room to retune travel on the machine rather than on the order form. It is double-acting: 100.5 N push and 86.4 N pull at 0.5 MPa, rising to 140.7 N push at 0.7 MPa.
Construction is the MA signature - a stainless round barrel, hard-chrome plated 6 mm rod and riveted aluminium-alloy covers that keep the footprint tight over the long stroke. For real work, figure on about 60 N at 0.5 MPa rather than the headline number, which translates to roughly a 5 kg vertical lift at a 2:1 margin. Anti-impact bumper pads are fixed rather than adjustable, and the standard piston magnet accepts CMSG, DMSG or EMSG switches out of the box.

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 MAJ16X300-20S Is Used
Diverter on a small sorting conveyor
Kicks lightweight cartons between two lanes; the 20 mm window absorbs layout tolerance and the DMSG-ready magnet signals the home position to the controller.
Parts nest lowering station
Drops a fixture nest 300 mm to an ergonomic height, lifting about 5 kg of nest and parts vertically with margin to spare at 0.5 MPa.
Glue head retraction on a cartoner
Pulls a hot-melt nozzle away from carton flaps between cycles; the air-powered return gives 86.4 N of pull at 0.5 MPa, enough to snap the head clear quickly.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X300-20S the Right Cylinder?
Neighbouring bores for comparison: this 16 mm pushes 100.5 N at 0.5 MPa, the 20 mm reaches 157.0 N and the 32 mm 402.2 N. Treat the stop screw as an extend-end position only - under air loss the rod still moves, so fit a separate lock if the application must hold position. On 300 mm of travel, side loads bend a 6 mm rod quickly, so guide the load or use an I or Y knuckle, and mount via the FA flange or LB foot option.
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 MAJ16X300-20S FAQ
Push 100.5 N, pull 86.4 N at 0.5 MPa; push 140.7 N at 0.7 MPa (pull 120.9 N); theoretical maximum 20.5 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-800 mm/s, with a 1/8" port on... actually the 16 mm bore uses M5x0.8.
No. The -20 window is set by an external stop screw that mechanically limits how far the rod extends, while the bumper pads at each end simply soften impact on landing. There is no adjustable air cushion on this model, and the stop must never be treated as a brake - the piston will still drift if air pressure is lost.
