About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X160-20S
Built for mid-range push on a short body, the MAJ32X160-20S pairs a 160 mm stroke with a 20 mm adjustable band: a stop screw sets the extend stroke anywhere from 140 to 160 mm on the machine. Double acting on filtered air at 0.15-1.0 MPa (22-145 psi), it turns 0.5 MPa supply into 402 N of push and 346 N of pull.
Riveting the aluminium covers and stainless block straight onto the barrel keeps the profile slim, while the hard-chrome 12 mm rod resists scoring in dusty plants. Size the real task at about 241 N at 0.5 MPa and the cylinder holds a 2:1 reserve; the built-in magnet and a DMSG switch give a clean extend signal at every trim position.

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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MAJ32X160-20S Is Used
Assembly press pre-load
Sets a short approach gap before a hand press seats bushings in gear housings; 563 N at 0.7 MPa nudges parts square into the nest every cycle.
Rotary table detent
Locks an indexing table against a hardened pin; the stop screw defines engagement depth across the 20 mm band, repeatable after every changeover.
Pick-station gate arm
Swings a safety gate arm at a warehouse pick point; the sealed riveted covers and stainless barrel shrug off corridor dust and damp floors.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ32X160-20S the Right Cylinder?
Against neighbours in the range, a 25 mm MA cylinder offers 245 N at 0.5 MPa and a 40 mm bore offers 628 N, so the 32 mm at 402 N is the balance point for loads from roughly 150 to 240 N. Do not use the stop screw as a load brake: it fixes the extend limit mechanically, yet the piston still coasts or drifts if supply air is lost. Choose FA flange or LB foot mounting, add I or Y knuckles where the load pivots, and on a 160 mm stroke at 30-800 mm/s keep side load off the rod or guide the carriage separately.
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 MAJ32X160-20S FAQ
Expect 402 N push and 346 N pull at 0.5 MPa, 563 N push and 484 N pull at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa. The ordered stroke is 160 mm; the external stop trims the extend stroke across a 20 mm window, so usable extend spans 140 to 160 mm. Running speed is 30-800 mm/s.
The rolled stainless barrel plus hard-chrome carbon-steel rod handles washdown-prone and outdoor points where painted bodies corrode, and the riveted round shell is slimmer than most extruded minis of equal bore. It is an AirTAC MA-family round-body design, with the magnet standard for CMSG, DMSG and EMSG switches.
