About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-75S
A wide 75 mm adjustment range makes the MAJ25X160-75S easy to re-set when product sizes change: the external stop screw shortens the 160 mm extend stroke to any point within that window, no shimming or cylinder swaps. Double-acting, it pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa over the full 160 mm of travel.
AirTAC rivets the aluminium-alloy covers and stainless block onto the high-precision stainless tube, giving a compact round body that resists corrosion in outdoor or food-area air. The two-way piston seal also retains grease for long service. Because the magnet is fitted as standard, CMSG / DMSG / EMSG switches drop on without a special-order piston - handy for confirming both end positions.

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 MAJ25X160-75S Is Used
Multi-size product chutes
Set a packaging chute to accept cartons of varying depths by trimming the extend stroke inside the 75 mm window between changeovers, with no cylinder change.
Position-confirmed stops
Pair the standard magnet with CMSG or DMSG switches so a PLC confirms the trimmed stop position before the next index on a sorter conveyor.
Fixture clamping on weld tables
Clamp sheet-metal panels during spot welding; 245.3 N at 0.5 MPa is ample clamp force and the stainless barrel tolerates coolant mist in the cell.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X160-75S the Right Cylinder?
Compare across the range before ordering: the 20 mm bore gives 157.0 N push at 0.5 MPa and 32 mm gives 402.2 N, so the 25 mm bore sits in the middle for light-to-medium gate and stop duty. In practice budget around 147 N (0.6 of the 245.3 N push figure) for real work at 0.5 MPa. The mechanical adjuster is an end stop only; if air pressure drops, the rod is free to move and will not hold a load mid-stroke. Mount with an FA flange or LB foot, add I or Y knuckles as needed; adjustable models have no SDB option. The 10 mm rod suits guided loads across a 160 mm stroke.
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 MAJ25X160-75S FAQ
Expect 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, and a 50 kgf theoretical ceiling at 1.0 MPa. Proof pressure is 1.5 MPa (215 psi) and the speed range is 30-800 mm/s.
An external stop screw mechanically limits the extend stroke anywhere within 75 mm of the 160 mm ordered stroke. It shortens the stroke only and acts as a stroke-end stop, not a mid-stroke lock; fixed bumper pads absorb the impact at each end.
