About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X160-30S
AirTAC's MAJ20X160-30S pairs a 160 mm extend stroke with a 30 mm trim window, adjusted by an external stop screw right on the machine. Feeding 0.5 MPa, the bore 20 piston delivers 157 N on the push side and 131.9 N on the return; theoretical peak is 32 kgf at 1.0 MPa. The rolling-packed stainless tube and chrome-plated rod hold up in misty or lightly rinsed areas where painted bodies blister.
Two-way heterogeneous seals double as grease reservoirs, so the 30-800 mm/s speed range stays smooth over long runs. Anti-impact bumpers are fixed - they absorb end-of-stroke shock only and are not an adjustable air cushion. Size the work around 94 N at 0.5 MPa instead of the headline 157 N, and remember the stop screw is a mechanical end stop, not a mid-stroke lock: on air loss the rod still drifts.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAJ20X160-30S Is Used
Tote diverter blade
Swings a diverter blade on a warehouse sorter, with the 30 mm window matching three different tote depths.
Tooling depth stop
Sets a drill depth stop on a bench-top tapping machine, adjusted per batch through the stop screw.
Gate latch on AGV dock
Latches a charging-station gate for indoor AGVs in a damp basement, where the stainless barrel resists condensation.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X160-30S the Right Cylinder?
Sizing rule of thumb: at 0.5 MPa take about 94 N of the 157 N push as usable force; if your tooling needs more, the 25 mm bore's 245.3 N or the 32 mm bore's 402.2 N are the next steps in the same MAJ series. The -30 window lets the cylinder cover a range of part sizes without re-piping. Choose FA flange or LB foot for the body, and I / Y knuckles on the rod end for swinging loads. Sensor feedback is free of special orders - the magnet is standard, so CMSG / DMSG / EMSG switches mount straight onto the barrel. Long strokes like 160 mm punish side load, so guide the mechanism rather than the cylinder.
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 MAJ20X160-30S FAQ
Push 157 N / pull 131.9 N at 0.5 MPa; push 219.8 N / pull 184.7 N at 0.7 MPa; 32 kgf theoretical maximum at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) filtered air, withstands 1.5 MPa (215 psi) proof pressure, and cycles at 30-800 mm/s.
No. The MAJ carries fixed anti-impact bumper pads that soften the shock at each end of travel - they decelerate the piston but cannot be tuned like an air cushion. If you need adjustable cushioning, AirTAC's MACJ series combines it with the same adjustable stroke.
