Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X125-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X125-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 125mm 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 MACJ63X125-10S
A 125 mm stroke with a tight 10 mm trim window makes the MACJ63X125-10S the pick when the travel is nearly right but the last few millimetres must be exact. AirTAC builds it double-acting with variable air cushions at both ends, rated 1557.9 N push at 0.5 MPa across a 0.15-1.0 MPa (22-145 psi) supply.
The rolled stainless barrel and 20 um hard-chrome rod stand up to humid, food-grade and outdoor air where painted mini cylinders blister. For sizing, treat about 935 N - 60% of the 0.5 MPa push - as the realistic continuous duty figure; on a vertical axis the full 158 kgf halves to roughly 79 kg of safe lift.

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 MACJ63X125-10S Is Used
Depth stop on a multi-spindle drill
Sets hole depth within 10 mm on a drilling head; the trim window replaces shims whenever the tooling is reground.
Pallet stop in a cold-store conveyor
Stainless construction and a 317.7 kgf force class cope with chilled, damp air at -20 C and repeated heavy tote impacts.
Gauge riser on an inspection fixture
Raises a dial gauge to height before each measurement; an EMSG switch confirms the retracted home position.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X125-10S the Right Cylinder?
Below 63 mm there is only the 50 mm bore at 981.3 N push (0.5 MPa), so if your job needs this force class, this is as high as the MA range goes. The 10 mm window means you should order the stroke close to final: you fine-tune within 10 mm and cannot stretch past 125 mm. The stop screw is an end stop only - with air lost the piston drifts freely, so park heavy loads on an external support.
Magnet is standard, so CMSG, DMSG or EMSG switches read position straight off the barrel. Mount via FA flange, LB foot, or I / Y knuckles on the rod end.
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 MACJ63X125-10S FAQ
At 0.5 MPa: 1557.9 N push, 1457.4 N pull. At 0.7 MPa: 2181.0 N push, 2040.3 N pull. Theoretical maximum: 317.7 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s, fluid air filtered to 40 um, 1/4" ports.
The covers are rolled onto the stainless barrel in one pressing, so there are no fasteners to relax and no separate gasket faces to weep. With the 20 um hard-chrome plated rod, the joint stays sealed through washdown and temperature swings from -20 to +70 C, where bolted miniature bodies often need re-torquing.
