About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X40-10S
Short, tunable and narrow, the MAJ16X40-10S produces 40 mm of double-acting stroke from a 16 mm stainless barrel, with the extend stroke trimmed inside a 10 mm window by an external stop screw. This is the smallest bore in the MA range: it pushes 100.5 N at 0.5 MPa and 140.7 N at 0.7 MPa, which works out to about 60 N of practical push once a working margin is kept.
The riveted round body stays sealed without tie-rods, so it slips into compact fixtures that larger minis cannot. A hard-chrome plated 6 mm rod runs in a grease-storing two-way seal, keeping friction stable across millions of cycles at 30-800 mm/s. Air ports are M5x0.8, and because the magnet is built in as standard, a CMSG or EMSG switch clamps straight onto the barrel.

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 MAJ16X40-10S Is Used
Eject pin on a connector crimping press
Kicks finished terminals clear of the die in 40 mm; 140.7 N push at 0.7 MPa handles sticky terminals, and the 10 mm window sets exact ejection height.
Part kicker at a vision inspection gate
Sweeps off-spec components into a reject bin; the built-in magnet with a DMSG switch logs every kick for the quality record.
Index pin on a small rotary indexing table
The 6 mm chrome rod engages index holes repeatably; an FA flange bolts flat to the frame while the stop screw fine-tunes pin protrusion within 10 mm.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X40-10S the Right Cylinder?
At 100.5 N push and 86.4 N pull at 0.5 MPa, this smallest MA bore suits light clamping and part kicking; when a fixture grows, the 20 mm bore gives 157 N push and the 25 mm bore 245 N. The 10 mm window dials the extend end in with the stop screw, but treat it as an end stop rather than a brake - an unpressurized piston still moves under load.
FA flange or LB foot mounting plus an I or Y knuckle covers most small-fixture layouts, and the standard-fit magnet lets a CMSG or DMSG switch read the trimmed end position without any option. At 40 mm stroke rod bending is not a concern, though squaring the tooling to the rod still extends seal life.
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 MAJ16X40-10S FAQ
Double-acting output on the 16 mm bore: 100.5 N push and 86.4 N pull at 0.5 MPa, rising to 140.7 N push and 120.9 N pull at 0.7 MPa, with a 20.5 kgf theoretical maximum at 1.0 MPa. Air connection is M5x0.8, the rod thread is M6x1.0 on a 6 mm rod, working pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
The stop screw limits the extend stroke within the 10 mm window by acting as a hard mechanical stop, while the fixed bumper pads beneath it only soften the final impact. Neither provides an adjustable air cushion - that belongs to the MACJ series - and the stop never secures a load by itself.
