About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X250-40S
Wide tolerance on part position? The MAJ16X250-40S lets the extend stroke float across a 40 mm band, 210 to 250 mm, set by a single external screw. This is a double-acting 16 mm mini cylinder rated 100.5 N push and 86.4 N pull at 0.5 MPa within a 0.15-1.0 MPa (22-145 psi) working range.
The 6 mm hard-chrome rod (20 um plating) runs in a stainless tube rolled into aluminium covers, a build that survives outdoor gates and damp food benches where coated bodies blister. A standard-fit magnet feeds CMSG, DMSG or EMSG switches for end-of-stroke confirmation, and the fixed bumper pad softens each landing without cushion needles. Expect about 5 kg of vertical lift with a 2:1 margin, derived from the 100.5 N rating.

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 MAJ16X250-40S Is Used
Battery tray locator
Positions light EV battery trays on an assembly skid; the 40 mm window absorbs casting variation from 210 to 250 mm with one unit.
Bottle rejector
A swept deflector pushes off-spec 200 ml bottles off a bottling rail; the stainless barrel and chrome rod laugh at constant rinse splash.
Camera z-stage
Raises a 500 g vision column; 100.5 N at 0.5 MPa equates to about 5 kg of vertical lift at a 2:1 margin, so headroom is generous.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X250-40S the Right Cylinder?
The 16 mm bore sits at the bottom of the MAJ ladder with 100.5 N at 0.5 MPa; the 20 mm and 25 mm bores offer 157.0 N and 245.3 N if the job grows. Pick FA flange or LB foot, and note the trim window only reduces stroke - extending beyond the ordered 250 mm is impossible. A long 250 mm stroke on a 6 mm rod wants guided, centred loading to avoid rod bending, and the stop will not arrest a drifting piston on air loss.
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 MAJ16X250-40S FAQ
At 0.5 MPa: 100.5 N push, 86.4 N pull. At 0.7 MPa: 140.7 N push, 120.9 N pull. Theoretical ceiling: 20.5 kgf at 1.0 MPa. Supply air is 0.15-1.0 MPa (22-145 psi) and the port is M5x0.8 on this 16 mm bore.
The high-precision stainless tube paired with a 6 mm hard-chrome plated rod resists corrosion on damp or outdoor stations where painted mini cylinders blister. Aluminium covers are rolled onto the barrel for a compact, reliably sealed body.
