Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X80-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X80-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 80mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X80-10S
Fine positioning is the MACJ25X80-10S job: its 10 mm window lets you shave the extend stroke between 70 and 80 mm to dial in a seating or registration point to the millimetre. Air drives the piston both ways, and a variable cushion at each end tames the stop at either limit across the 30-800 mm/s range.
The bore 25 piston pushes 245.3 N at 0.5 MPa - about 25 kg of vertical-lift equivalent, or roughly 12 kg with a 2:1 margin. AirTAC's MA build, a stainless barrel with a 20 um hard-chrome rod inside riveted aluminium covers, gives real corrosion resistance in damp, food-grade or outdoor locations, and cushioning is adjustable at both ends so deceleration matches the load.

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 MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X80-10S Is Used
Seating press for bearings in a motor assembly cell
The 70-80 mm fine trim dials in exact seating depth for different bearing heights, with the variable cushion easing the last millimetres of ram travel.
Z-lift on a small pick-and-place gantry
About 25 kg of vertical-lift equivalent at 0.5 MPa - halve it for a 2:1 margin and it comfortably raises 12 kg camera housings between conveyor and packing tray.
Register adjustment on a printing roll stand
A 10 mm window is exactly what register setting needs; the stainless rod resists ink-solvent wipe-downs and the magnet feeds a DMSG switch for position readback.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X80-10S the Right Cylinder?
Sizing context: dropping to bore 20 costs you force (157 N push at 0.5 MPa), while bore 32 buys 402.2 N, so choose this 245.3 N bore 25 when the load sits in the middle and plan around 147 N of usable push. The 10 mm trim is a fine-setting stop, not a position lock - on air loss the rod still drifts, so hold loads with valving instead. FA flange or LB foot mounting, I or Y knuckles at the rod end, and the built-in magnet is ready for CMSG, DMSG and EMSG switches.
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 On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X80-10S FAQ
245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push at 0.7 MPa, 50 kgf theoretical at 1.0 MPa. Extend stroke adjusts across a 10 mm window (70 to 80 mm), both ends are variably cushioned, speed 30-800 mm/s, pressure 0.15-1.0 MPa (22-145 psi).
It cannot. The external adjuster is a mechanical end stop that shortens the extend stroke within the 10 mm window; if air pressure drops, the piston drifts freely, so use a blocking valve or counterbalance circuit wherever position must be held.
