Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X25-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X25-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø50mm bore and 25mm stroke, 1/4" 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 MACJ50X25-10S
Short stroke, full muscle: the MACJ50X25-10S concentrates a 50 mm bore - 981 N of push at 0.5 MPa - into just 25 mm of travel, with a 10 mm window for on-site trimming of the extend stroke. Double-acting with a variable cushion at both ends, it suits clamp and press points where space is tight but force is not.
Inside is the standard MA construction: a riveted stainless barrel, aluminium covers and a hard-chrome carbon-steel rod that tolerates coolant mist and washdown. For sizing, about 589 N of that 0.5 MPa rating is a sensible working force, or think of it as lifting roughly 50 kg vertically with a 2:1 margin. Cycle speeds of 30-800 mm/s and a built-in magnet compatible with CMSG, DMSG or EMSG switches round out the package.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MACJ50X25-10S Is Used
Connector seating on an assembly cell
Presses board-mounted connectors home with controlled force; the 10 mm trim lets technicians set exact seating depth without shimming the fixture.
Pneumatic clamp on a welding jig
Holds tube or sheet parts against a weld fixture with about 589 N of working force, standing up to sparks and spatter better than painted-bodied clamps.
Stopper press on a lab filler
Seats stoppers into small vials over a 25 mm stroke, where the dual cushions prevent the crisp, high-speed landing that cracks glass.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ50X25-10S the Right Cylinder?
This 50 mm bore sits between bore 40 (628 N at 0.5 MPa) and bore 63 (1558 N), so choose it when a 40 mm unit feels marginal but the envelope cannot stretch. The 25 mm stroke keeps the body compact for crowded fixtures; mount via FA flange or LB foot and fit an I or Y knuckle for pivoting clamps. Remember the -10 adjuster only sets the extend endpoint - under lost air the rod can still be pushed back, so it is no substitute for a load-holding valve.
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 MACJ50X25-10S FAQ
Push 981 N and pull 881 N at 0.5 MPa; push 1374 N and pull 1233 N at 0.7 MPa; theoretical maximum about 200 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof is 1.5 MPa (215 psi), and the 1/4" port serves the 50 mm bore.
Use the FA flange or LB foot for body fixing and an I or Y rod knuckle where the clamp point pivots. Sensing needs no special order - the magnet comes built in, so CMSG, DMSG or EMSG switches position anywhere along the stainless barrel to flag extend and retract. Within the 10 mm window, the stop screw sets exactly where the extend stroke ends.
