Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø25mm bore and 60mm 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 MACJ25X60-20S
A compact double-acting actuator for jobs where the extend stroke must land at a precise point: the 20 mm trim window lets a stop screw pull the 60 mm extend stroke back to any setting inside that band, with a variable air cushion softening both ends. The 25 mm bore delivers 245.3 N of push at 0.5 MPa and 206.1 N of pull.
The round body is a stainless barrel riveted to aluminium covers, driving a hard-chrome plated rod, so it stands up to washdown and damp shop air far better than painted mini cylinders. For sizing, count on roughly 147 N of real working push at 0.5 MPa - about 60 percent of the rating - which covers a 12 kg vertical lift at a 2:1 margin.

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 MACJ25X60-20S Is Used
Bearing press fit
Seating small bearings into aluminium housings at an electronics assembly bench, with the 20 mm window trimming travel to the seat depth.
Bottling line stopper gate
A pop-up stopper that halts PET bottles ahead of the filler; the end cushion keeps the gate quiet at high cycle counts.
Carton flap tucker
Folding top flaps on a small carton sealer, where the stainless barrel handles daily wipe-down around glue and product spill.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-20S the Right Cylinder?
Compare bores by force: a 20 mm unit manages 157.0 N at 0.5 MPa and a 32 mm reaches 402.2 N, so this 25 mm sits in the middle for clamp-and-eject work. The trim screw is a mechanical end stop only; if supply air drops the rod can drift, so add a lock or valve when true holding matters. Mount on an FA flange or LB foot, add an I or Y rod knuckle for swivelling tooling, and note the 1/8" ports and M10x1.25 male rod thread. A 60 mm stroke keeps side-load risk modest, but still keep lateral loads off the 10 mm rod. Position feedback needs no options - the piston magnet is built in 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 MACJ25X60-20S FAQ
At 0.5 MPa the MACJ25X60-20S pushes 245.3 N and pulls 206.1 N. Raise supply to 0.7 MPa and push climbs to 343.4 N with 288.5 N of pull. The theoretical ceiling is 50.0 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
An external stop screw shortens the extend stroke anywhere within the ordered 20 mm window - from the full 60 mm down to 40 mm. It trims the extend stroke only, cannot lengthen travel, and is not a mid-stroke lock: with air lost the rod still moves. The variable air cushion at both ends stays active at any setting.
