About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X110-30S
Bore 20 with an external trim screw is the workhorse size of the adjustable MAJ line: 157 N push at 0.5 MPa, rising to 219.8 N at 0.7 MPa. For sizing, treat about 94 N (0.6 of the 0.5 MPa rating) as the practical work force, which corresponds to lifting around 8 kg vertically with a 2:1 margin.
Running 30-800 mm/s on air filtered to 40 um within 0.15-1.0 MPa (22-145 psi), the cylinder uses a riveted stainless round body with a hard-chrome plated rod that stands up to damp and mildly corrosive spots. Fixed bumper pads tame stroke-end shock without acting as an adjustable cushion, and a magnet is built in as standard for CMSG / DMSG / EMSG switching.

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 MAJ20X110-30S Is Used
Small process valve actuator
Strokes a ball valve on a water-treatment skid; 157 N at 0.5 MPa seats small process valves with room to spare, and the trim screw sets exact opening angle.
Camera head Z-lift
Raises an inspection camera of around 8 kg between two imaging stations, the 30 mm window absorbing mechanical mounting tolerance.
Light bushing press-fit
Seats nylon bushings into plastic housings with roughly 94 N of usable force at 0.5 MPa, well matched to delicate assembly work.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X110-30S the Right Cylinder?
Between the 16 mm bore (100.5 N) and the 25 mm bore (245.3 N) at 0.5 MPa, bore 20 fits medium mini-cylinder duties. Mount via FA flange or LB foot; I and Y knuckles handle rod-side pivots. The 30 mm window trims the extend stroke shorter on site, but the stop is a mechanical end position only, never a mid-stroke lock, so a suspended load can sag if air is lost.
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 MAJ20X110-30S FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa it reaches 219.8 N push and 184.7 N pull. Theoretical maximum at 1.0 MPa is 32.0 kgf. The port is 1/8", the rod thread M8x1.25 on an 8 mm rod, proof pressure 1.5 MPa (215 psi) and speed range 30-800 mm/s.
FA flange and LB foot mounts are standard options, with I and Y rod knuckles for pivoting linkages. Sensing needs no extras: the magnet is built in on every MA-series cylinder, so CMSG, DMSG and EMSG switches mount directly. PT thread is the default; G or NPT ports are specification options to order.
