About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X15-20S
A 20 mm adjust window on a 15 mm stroke gives near-zero-travel tuning - useful when a fixture's closed height changes between batches. At 0.5 MPa the bore-16 piston develops 100.5 N; treat about 60 N of that as dependable output after margins, rising to 140.7 N at 0.7 MPa.
The stainless round barrel is rolled onto aluminium-alloy covers for a slim, sealed body, and the carbon-steel rod carries a 20 um hard-chrome skin that takes repeated touch cycles without rust blooms. Magnets ship built in, so CMSG, DMSG and EMSG switches read end positions out of the box. The trim screw caps the extend stroke only; it is not a brake, and the rod still moves if air is lost.

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 MAJ16X15-20S Is Used
Blister tray gate
Swings a gate on a blister packaging line; the 20 mm window lets technicians close the swing angle precisely to the lane.
Bench-drill depth stop
Acts as the depth stop plunger on a manual bench drill, trimming engagement up to 20 mm between material batches.
Micro lever toggle
Toggles a small bail lever on a bottling fixture; 100.5 N at 0.5 MPa trips the lever with margin to spare.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X15-20S the Right Cylinder?
If the trimmed stroke must still carry real force, compare against bore 20 at 157.0 N and bore 25 at 245.3 N (0.5 MPa push) before committing. The 20 mm window dwarfs the 15 mm base stroke, so confirm the minimum travel your process tolerates before ordering. Choose FA flange for face mounting or LB foot for base mounting, and add an I or Y knuckle where a pivoting link is wanted.
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 MAJ16X15-20S FAQ
It pushes 100.5 N and pulls 86.4 N at 0.5 MPa; at 0.7 MPa, 140.7 N push and 120.9 N pull. The theoretical maximum at 1.0 MPa is 20.5 kgf. Speed spans 30-800 mm/s and pressure 0.15-1.0 MPa (22-145 psi).
FA flange and LB foot mounts, plus I and Y rod knuckles on the M6x1.0 thread. The built-in magnet is standard, so CMSG / DMSG / EMSG switches detect end positions with no special-order piston.
