About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X130-20S
Where repeatability beats raw force, this model pairs a 130 mm base stroke with a 20 mm external adjuster for the extend direction. Expect 157 N extend and 131.9 N retract at 0.5 MPa, 219.8 N extend at 0.7 MPa; theoretical maximum force is 32 kgf at 1.0 MPa.
The bumper-fitted, riveted round body is classic AirTAC MA mini construction: stainless barrel, aluminium covers, hard-chrome plated carbon-steel rod. For vertical duty, the 157 N figure converts to about 8 kg of lift once a 2:1 margin is applied. A built-in magnet comes standard for CMSG / DMSG / EMSG sensing.

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 MAJ20X130-20S Is Used
Bottling-line chute diverter
Push a flow diverter between two fill lanes; 157 N at 0.5 MPa moves the gate briskly while the 20 mm window dials in the exact park position.
Machining fixture stop
Act as a retractable workpiece stop on a small milling or drilling fixture; the external stop screw sets the stop height without shimming.
Part-presence gate
Drop a checking pin into a machined feature and confirm seating via a CMSG switch on the barrel before the cycle releases the part.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ20X130-20S the Right Cylinder?
Compare 100.5 N from the 16 mm bore and 245.3 N from the 25 mm bore: the 20 mm bore at 157 N (0.5 MPa) covers light pick-and-place duties between them. The -20 adjuster is a mechanical end stop for the extend direction, so on air failure the rod can still drift - add a check or locking valve if holding matters. FA flange and LB foot mountings plus I / Y knuckles are available; the air port is 1/8", rod thread M8x1.25, magnet standard.
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 MAJ20X130-20S FAQ
MAJ20X130-20S gives 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a 32 kgf theoretical maximum at 1.0 MPa. Design near 94 N of real work at 0.5 MPa for a comfortable margin.
Choose FA flange or LB foot brackets, and add an I or Y rod knuckle for swivel joints. The air connection is a 1/8" port and the male rod thread is M8x1.25. Because the magnet is standard, CMSG / DMSG / EMSG switches snap onto the stainless barrel for stroke-end detection.
