Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-50S 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 MACJ63X100-50S
Heavy pushes and a half-window of trim: the MACJ63X100-50S pairs a 100 mm stroke with a 50 mm adjustable extend range and a variable cushion at each end. This is the strongest bore in the MA mini line, pushing 1557.9 N at 0.5 MPa - about 935 N of dependable working force once a 60 percent duty factor is applied.
Build quality matches the rating: a stainless round barrel riveted to aluminium-alloy covers, a 16 mm hard-chrome rod, and heterogeneous piston seals that hold grease between service intervals. In food halls, outdoor fixtures and wet machining cells it outlasts painted-steel minis that chip and pit.

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 MACJ63X100-50S Is Used
Lab press for material coupons
Dial the extend stop through the 50 mm window when switching coupon thicknesses, relying on the front cushion for soft seating.
Carton diverter on roller conveyor
Sweeps cartons across a diverter at speeds up to 800 mm/s, with the cushion taking the sting out of the divert strike.
Bench press for bushing removal
Around 935 N of practical working force presses armature bushings out of starter motor housings in an auto-electric shop.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-50S the Right Cylinder?
This is the ceiling of the series - no MA bore exists above 63 mm - so treat 981.3 N (the 50 mm push at 0.5 MPa) as your step-down point and move to a larger AirTAC series once working loads exceed about 935 N. The 50 mm window suits multi-product fixtures where the extend stop is moved between recipes.
The 1/4" ports and M14x1.5 male rod thread keep plumbing simple, FA flange and LB foot mounts suit static fixtures, and the standard magnet pairs with CMSG / DMSG / EMSG switches for position feedback. On air failure the rod is free to move - the adjuster trims stroke, it does not lock the load.
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 MACJ63X100-50S FAQ
Push is 1557.9 N at 0.5 MPa and 2181.0 N at 0.7 MPa; pull is 1457.4 N at 0.5 MPa and 2040.3 N at 0.7 MPa. Peak theoretical force is 317.7 kgf at 1.0 MPa. Design around a 0.15-1.0 MPa (22-145 psi) supply and a 1.5 MPa (215 psi) proof pressure.
The riveted stainless barrel with a 20 um hard-chrome plated rod handles humidity, splash and mild washdown without the chipping and rust you get on painted bodies. The two-way piston seal also retains grease, cutting lubrication visits over the cylinder's life.
