Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 225mm 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 MACJ63X225-50S
Adjustability defines this model: the MACJ63X225-50S keeps a 225 mm stroke but lets the extend side be shortened anywhere within a 50 mm band using the built-in stop screw. Under that control sits a 63 mm double-acting piston making 1557.9 N push and 1457.4 N pull at 0.5 MPa, with variable air cushions softening both ends of travel.
The stainless barrel and 20 um hard-chrome rod shrug off corrosion in humid plants and outdoor rigs alike, an edge over painted minis. Sized sensibly, expect about 935 N of working push at 0.5 MPa; halve the 158.8 kgf lift equivalent and the bore raises near 79 kg with margin. Sensing is plug-and-play because the piston magnet is fitted as standard on every MA cylinder.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 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 MACJ63X225-50S Is Used
Pusher on a scrap steel transfer conveyor
The 1557.9 N thrust at 0.5 MPa clears heavy offcuts off the belt, and the 50 mm trim window matches the pusher face to different lane widths.
Lid clamp on a 200 L drum filling station
Pneumatic clamping at roughly 935 N working force seats filling heads on drums; variable cushions keep the clamp from shocking the drum rim.
Height setting on a grain sampling arm
The 50 mm adjuster sets sampling depth per crop batch outdoors, where the stainless barrel resists rain and dust better than painted bodies.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X225-50S the Right Cylinder?
Compare before committing: a 32 mm MACJ manages 402.2 N at 0.5 MPa, so jobs of this weight class at 225 mm genuinely need the 63 mm bore. Hold applied force near 935 N to extend seal life. The stop screw positions the extend stroke only against air pressure - a lost supply lets the rod creep, so fit a check or locking valve where holding matters. FA flange and LB foot are the catalogue mounts; I and Y rod knuckles cover swivel tooling.
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 MACJ63X225-50S FAQ
At 0.5 MPa the piston pushes 1557.9 N and retracts with 1457.4 N. Raise the supply to 0.7 MPa and output becomes 2181.0 N and 2040.3 N. Theoretical maximum at 1.0 MPa is 317.7 kgf. Rated pressure is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).
Yes, within reason. The barrel is stainless steel, the 16 mm rod carries 20 um of hard chrome, and the riveted aluminium covers seal the body without external fasteners. It runs on 40 um filtered air from -20 to +70 C, so splashed, humid or outdoor locations are well within its comfort zone.
