Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X50-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X50-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 50mm 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 MACJ25X50-10S
A 245 N push at 0.5 MPa puts the MACJ25X50-10S in the workhorse band for 25 mm minis - strong enough for clamping and part transfer, light enough to run off a small FRL. Push rises to 343.4 N at 0.7 MPa, and the theoretical ceiling at 1.0 MPa is 50 kgf. The stainless round barrel with rolled aluminium covers and a 20 um hard-chrome rod holds up where painted minis blister: coolant splash, washdown aisles, outdoor enclosures.
The -10 code gives a short 10 mm trim window, ideal when the 50 mm stroke is right but the final approach needs a few millimetres shaved off. Both ends carry a variable air cushion, and the piston magnet is fitted as standard for CMSG / DMSG / EMSG switches.

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 MACJ25X50-10S Is Used
Fixture clamp on a CNC tombstone
Holds parts mid-stroke with about 245 N of clamping at 0.5 MPa; the 10 mm window fine-tunes clamp travel so the jaw bottoms on the part, not the fixture.
Tray lift assist in a small parts sorter
Raises trays near 12 kg with a 2:1 safety margin; the stainless barrel survives daily wipe-downs in the sorting cell.
Bottle pusher on a rinsing machine
Cushioned stroke seats PET bottles into pockets without cracking shoulders, and the built-in magnet triggers a CMSG switch to confirm full seat.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X50-10S the Right Cylinder?
Scale the bore to the job: bore 20 offers 157.0 N at 0.5 MPa for lighter eject tasks, bore 32 reaches 402.2 N when the load grows past 240 N. For this model, budget roughly 147 N of usable push at 0.5 MPa - about 12 kg lifted vertically at a 2:1 margin - and mount with FA flange or LB foot, adding I / Y knuckles for pivoting joints.
One caution: the stop screw is a stroke limiter only. It will not lock the rod against back-driving if supply air is lost, so use a separate check or lock for held 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 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 MACJ25X50-10S FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; 50 kgf theoretical at 1.0 MPa. Operating pressure 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, bore 25 mm with a 10 mm hard-chrome rod, 1/8" ports, 50 mm stroke and a 10 mm adjustable window.
The riveted stainless barrel plus hard-chrome rod resists moisture, coolant and mild washdown far better than painted or bare aluminium minis, and the variable air cushion at both ends lets you run fast cycles without hammering the covers. Mounting is FA flange, LB foot or I / Y rod knuckles.
