Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X75-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X75-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø63mm bore and 75mm 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 MACJ63X75-20S
The 63 mm bore of the MACJ63X75-20S delivers 1557.9 N forward and 1457.4 N back at 0.5 MPa, climbing to 2181.0 N of push at 0.7 MPa - about 317 kgf of theoretical force at a full 1.0 MPa supply. This is AirTAC's double-acting adjustable mini cylinder with a variable air cushion at both ends, and the external stop screw trims the extend stroke anywhere inside the ordered 20 mm window.
A riveted stainless round barrel with a hard-chrome plated 16 mm rod shrugs off washdown and damp plant air, a real edge over painted mini cylinders in food or outdoor duty. For sizing, expect about 935 N of usable push at 0.5 MPa once you de-rate to 60 percent for seal friction and control losses. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip on without a special-order piston. Supply runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.

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 MACJ63X75-20S Is Used
Bushing ejector
Ejects pressed-in bushings from housings on an automotive subassembly press; the 20 mm trim window sets the knock-out travel after each tooling change.
Case pusher
Pushes full crates off a bottling conveyor at a divert point; 1558 N of push at 0.5 MPa moves a loaded case without an air booster.
Carton flap tamping
Tamps folded carton flaps before taping on a packaging line; the variable cushion at both ends keeps the action smooth even at 800 mm/s.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X75-20S the Right Cylinder?
If 1557.9 N at 0.5 MPa overshoots your duty, the 50 mm bore of the same series still gives 981.3 N; bore 63 is the ceiling of the MA range, so there is nothing larger to step up to. Choose FA flange or LB foot mounting, and add I or Y rod knuckles if the tooling needs a swivel - adjustable versions drop the SDB option. Remember the -20 stop screw only shortens the extend stroke; it will not hold a load against air loss, so fit a locking valve where the rod must stay put. Ports are 1/4" and the rod thread is M14x1.5.
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 MACJ63X75-20S FAQ
At 0.5 MPa it pushes 1557.9 N and pulls 1457.4 N; at 0.7 MPa those rise to 2181.0 N and 2040.3 N. The theoretical maximum is 317.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), speed is 30-800 mm/s, and the extend stroke trims within the ordered 20 mm window.
No. Every MA-series cylinder carries a built-in magnet as standard, so CMSG, DMSG and EMSG switches mount straight onto the stainless barrel. The variable air cushion at each end also softens the 75 mm travel when running near the top of the speed range.
