About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X350-40S
Long reach in a small round body: the MAJ16X350-40S spans 350 mm - a made-to-order stroke above the 300 mm standard for this bore - and its external stop screw trims up to 40 mm off the extend side on site. Push is 100.5 N at 0.5 MPa and pull 86.4 N, rising to 140.7 N at 0.7 MPa, with 20.5 kgf as the theoretical maximum at 1.0 MPa. The hard-chrome plated rod on a stainless barrel resists corrosion in wet or dusty plants where painted minis flake.
Budget roughly 60 N for real work at 0.5 MPa; vertically that is about 5 kg of lifted part after halving the 10 kg figure for margin. The fixed bumper pad decelerates the piston at stroke end without being an adjustable air cushion, and the standard built-in magnet means CMSG / DMSG / EMSG switches mount with no piston upgrade.

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 MAJ16X350-40S Is Used
Cross-belt tote pusher
Sideways pushes small totes off a wide roller conveyor into a sorting chute; 100.5 N at 0.5 MPa suits light loads across the full 350 mm sweep.
Guard-door slide
Slides a CNC cell guard panel 350 mm open, trimming the travel up to 40 mm with the stop screw so the door parks clear of the light curtain.
Rack-lane transfer
Shifts bread trays between two lanes of a bakery rack loader; the stainless barrel and chrome rod stand up to flour dust and washdown routines.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X350-40S the Right Cylinder?
The 350 mm stroke sits past the 300 mm standard ceiling for bore 16, so this unit is made to order - state the exact stroke when you enquire. Force-wise, 100.5 N push at 0.5 MPa suits light transfers; bore 20 raises the same figure to 157 N if the load grows. The trim screw is an end stop, not a mid-stroke lock: on air loss the rod can drift, so fit a valve or external clamp where holding matters. Mount via the FA flange or LB foot and guide long strokes externally to protect the 6 mm rod from bending.
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 MAJ16X350-40S FAQ
Push is 100.5 N and pull 86.4 N at 0.5 MPa; at 0.7 MPa expect 140.7 N push and 120.9 N pull. Theoretical maximum force at 1.0 MPa is 20.5 kgf. Operating window: 0.15-1.0 MPa (22-145 psi), 30-800 mm/s, on air filtered to 40 um.
Not a problem, but it is a made-to-order build rather than a catalogue stroke. Send the exact required stroke and mounting (FA flange or LB foot) with your enquiry and the cylinder is produced to that length; the 40 mm extend-trim window stays exactly as ordered.
