Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-100S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-100S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 100mm 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 MACJ63X100-100S
Pushing, positioning and fine-tuning come together in the MACJ63X100-100S: a 63 mm round stainless body that drives 100 mm of stroke with 1558 N of push and 1457 N of pull at 0.5 MPa, climbing to 2181 N and 2040 N at 0.7 MPa. Because the adjustable window equals the full stroke, the extend stop screw can shorten the effective throw anywhere from a few millimetres up to 100 mm - dial it in on the machine rather than on the order form.
At 317.7 kgf theoretical maximum this is the top force class of the MA series, yet the riveted barrel-and-cover build stays slimmer than many profile minis. Derate to about 935 N of continuous working push and the cylinder lifts about 79 kg vertically with a 2:1 margin, or about 159 kg at the raw rating. A variable cushion at each end protects the covers whenever the load arrives fast.

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 MACJ63X100-100S Is Used
Carton push-off
Kicking sealed boxes off a conveyor lane into a chute, where 100 mm of travel crosses the belt and about 935 N of derated push handles full cartons.
Interlocked guard slide
Sliding a machine safety gate open and closed, with the cushion absorbing the slam and the stop screw capping how far the gate travels.
Mould slide core pull
Drawing a slide core in a small injection mould, where the trim window lets the moulder shorten the pull after tooling changes.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-100S the Right Cylinder?
A 100 mm stroke at bore 63 is long enough that side loads matter: guide the load externally or fit an I or Y rod knuckle, since rod bending - not thrust - usually limits life on unguided pushes. If the 981 N at 0.5 MPa from a 50 mm bore covers the job, the smaller MACJ50 saves space; 63 mm is the ceiling of the range, so there is no step up. Mount via the FA flange or LB foot; note the adjustable version carries no SDB option, and the stop screw sets the extend limit without locking the load against drift when air pressure drops. CMSG, DMSG and EMSG switches work with the standard magnet straight out of the box.
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 MACJ63X100-100S FAQ
Supply 0.15-1.0 MPa (22-145 psi) and you get 1558 N extend force and 1457 N retract force at 0.5 MPa, or 2181 N and 2040 N at 0.7 MPa; peak theoretical output is 317.7 kgf at 1.0 MPa. The extend stroke trims within the 100 mm window, cushioning is variable at both ends, and speed covers 30-800 mm/s.
The barrel is stainless steel and the rod is carbon steel with a 20 um hard-chrome plate, so washdown, condensation and outdoor exposure do not chew through a coating the way they do on painted aluminium bodies. Riveted aluminium covers keep the seal line tight for the life of the cylinder.
