About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-30S
The 25 mm bore of this AirTAC MAJ25X160-30S carries a 30 mm on-site trimming range for the extend stroke, set by an external stop screw; both directions remain fully air-driven. Rated output is 245.3 N push and 206.1 N pull at 0.5 MPa within a 0.15-1.0 MPa (22-145 psi) working band.
A stainless barrel plus a hard-chrome 10 mm rod means the cylinder tolerates occasional rinse-down in packaging or bottling rooms without paint flaking into product zones, and the two-way piston seal doubles as a grease store to stretch lubrication intervals. Divide the 245.3 N push by gravity and you get 25 kgf; halve that and the rod lifts about 12 kg vertically with a comfortable margin. A built-in magnet ships on every unit - mount CMSG or EMSG switches for end-of-stroke confirmation straight out of the box.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 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 MAJ25X160-30S Is Used
Kicker Arm on a Food-Grade Conveyor
The arm kicks misaligned tubs off a dairy conveyor; rinse-down splash is no threat to the stainless barrel, and 245.3 N at 0.5 MPa moves tubs briskly at up to 800 mm/s.
Dosing Head Actuator in a CIP Zone
A clean-in-place dosing station strokes its head with the 25 mm bore; the grease-storing piston seal keeps the unit running between maintenance windows.
Tool Clamp on a Benchtop Fixture
The stop screw trims clamp travel across a 30 mm window so operators match fixture depth exactly; 343.4 N at 0.7 MPa secures aluminum workpieces without marring.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-30S the Right Cylinder?
Compare against neighbors before ordering: the 20 mm bore delivers 157.0 N at 0.5 MPa for lighter duty, while the 32 mm bore reaches 402.2 N when clamping forces rise. For this model pick FA flange or LB foot mounting, and bolt on I or Y knuckles if the tooling is not perfectly aligned - SDB is not part of the adjustable range.
The 30 mm trimming window shortens the extend stroke only; it never lengthens travel past the ordered 160 mm, and it does not hold position when air pressure drops. Guide any long 160 mm travel externally to protect the hard-chrome rod from bending loads.
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 MAJ25X160-30S FAQ
At 0.5 MPa: 245.3 N push and 206.1 N pull. At 0.7 MPa: 343.4 N push and 288.5 N pull. Theoretical maximum is 50 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), and speed range is 30-800 mm/s.
Yes - the stainless round barrel and hard-chrome plated carbon-steel rod resist mild corrosion and rinse-down splash, while the aluminium covers and grease-storing two-way seal keep maintenance light between shifts.
