Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-30S 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 MACJ25X60-30S
Set the extend stopping point in the field: the 30 mm window lets a technician dial the 60 mm stroke down inside that range to match the fixture, while the variable air cushion at both ends takes the shock out of faster cycles. Double-acting on filtered air, it pushes 245.3 N at 0.5 MPa.
Its riveted stainless barrel and 20 um hard-chrome rod shrug off coolant mist and washdown that would rust painted minis, and the aluminium covers keep the body light. Treat it as a 147 N pusher at 0.5 MPa for continuous duty; that is about a 25 kgf vertical rating, halved to 12 kg for a comfortable 2:1 lift 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 MACJ25X60-30S Is Used
Lab dispensing head
Driving a syringe-style reagent dispenser where the 30 mm trim sets a repeatable shot volume and the stainless body wipes clean.
Palletizer part pusher
Knocking cartons off a transfer plate into a collection chute, with 206.1 N of pull at 0.5 MPa snapping the pusher back quickly.
Rotary table index pin
A retractable index pin on a fixture table, cushioned at both ends so the pin seats without chatter on every index.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ25X60-30S the Right Cylinder?
Force check before you commit: bore 20 delivers 157.0 N at 0.5 MPa and bore 32 steps up to 402.2 N, so 25 mm is the mid option for this duty. Remember the adjuster is an extend-stroke end stop, not a brake - expect drift on air loss and fit a locking valve if the position must survive supply drops. FA flange and LB foot cover mounting; I and Y knuckles suit swivelling tooling. Ports are 1/8" and the standard magnet accepts CMSG / DMSG / EMSG switches, so sensing adds no cost. Rod thread is M10x1.25 male.
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 MACJ25X60-30S FAQ
Push is 245.3 N and pull 206.1 N at 0.5 MPa; at 0.7 MPa expect 343.4 N push and 288.5 N pull. The theoretical maximum is 50.0 kgf at 1.0 MPa. Run it on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s.
The stop screw sets the extend stroke anywhere from the full 60 mm down to 30 mm. Retract travel is unaffected. It is a mechanical end stop, not a load-holding brake - the piston can still be back-driven if supply air is lost, so add a locking valve where holding is critical.
