About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X170-20S
Machines needing a short, fine setting range get it here: the extend stroke of this 170 mm double-acting mini cylinder is trimmed within a 20 mm window by an external stop screw, with fixed bumper pads taking the shock at stroke ends. Bore 16 gives 100.5 N push and 86.4 N pull at 0.5 MPa.
The riveted stainless round body and hard-chrome plated 6 mm rod shrug off coolant mist and damp plant air, an edge painted minis lose over time. A magnet is standard on every MA cylinder, so CMSG / DMSG / EMSG switches clip straight on. Sizing rule of thumb: about 60 N of practical work at 0.5 MPa, and the rod hoists roughly 5 kg vertically with a 2:1 margin.

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 MAJ16X170-20S Is Used
Label applicator press
Presses labels onto cosmetic bottles at 30-40 cycles per minute; the 20 mm fine window dials in exact label seat depth.
Test tube rack indexing
Advances sample racks one position at a time in a laboratory analyser; the built-in magnet feeds a CMSG switch for position confirmation.
Micro welder clamp
Clamps thin sheet before tack welding; about 60 N of practical clamp force at 0.5 MPa suits 0.5 mm stainless shims.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X170-20S the Right Cylinder?
This is the smallest MA bore; if 100.5 N at 0.5 MPa feels tight, bore 20 offers 157 N and bore 32 reaches 402.2 N. Remember the stop screw shortens the extend stroke only and is no substitute for a load-holding brake - under air loss the piston coasts. Choose an FA flange or LB foot, add I or Y rod knuckles where the load pivots, and support long side loads because the 6 mm rod bends before it breaks at 170 mm reach.
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 MAJ16X170-20S FAQ
100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push at 0.7 MPa, and 20.5 kgf theoretical maximum at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, speeds 30-800 mm/s.
Every MA-series piston carries a magnet as standard, so AirTAC CMSG, DMSG and EMSG switches mount directly on the stainless barrel - no special-order piston and no retrofit magnet needed.
