About the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-40S

A 40 mm trim window and a 100 mm base stroke put the MACJ63X100-40S in the heavy end of the AirTAC MA mini family: double-acting, with a variable air cushion at both ends to soak up shock at cycle rates up to 800 mm/s. At 0.5 MPa the 63 mm bore pushes 1557.9 N, which works out to a vertical lift equivalent of about 159 kg before any margin is applied.

Halve that for a 2:1 factor and you can lift about 79 kg of real part weight per cycle. The riveted stainless barrel and 20 um hard-chrome rod resist corrosion in damp workshops and washdown zones, and because the magnet ships as standard, CMSG / DMSG / EMSG switches drop on without a special-order piston. The stop screw shortens the extend stroke only; it is not a load-holding brake, and the piston can still drift if supply pressure is lost.

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-40S Is Used

compress

Aluminum extrusion stop

Set the extend stop through the 40 mm window to butt extrusion lengths against a gauge at the saw, letting the rear cushion absorb the butt impact.

factory

Injection mold sprue punch

2181.0 N of push at 0.7 MPa shears sprues on PP molding machines, with both-end cushioning sparing the covers from hammering.

warehouse

Pallet gate actuator

Releases conveyor pallet gates in a bottling hall where washdown spray would rust a painted-steel mini cylinder within months.

Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ63X100-40S the Right Cylinder?

Drop to the 50 mm bore and its 981.3 N push at 0.5 MPa if your working load sits under about 589 N; stay at 63 mm when you need the full 1557.9 N. The 40 mm window gives more fine-travel than the -30 version, useful where product sizes change between batches. Since 63 mm tops the MA range, there is no larger bore to step up to in this series.

Mount it FA (flange) or LB (foot), add I or Y rod knuckles if the load is not in line, and keep side loads off the 16 mm rod - the hard-chrome plating is tough but the rod is not a guide. 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 MACJ63X100-40S FAQ

Expect 1557.9 N push and 1457.4 N pull at 0.5 MPa. At 0.7 MPa those rise to 2181.0 N push and 2040.3 N pull, and the theoretical peak is 317.7 kgf at 1.0 MPa. Pressure range is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi).

It sets how far the extend stroke can be shortened on site with the stop screw; the retract stroke stays 100 mm. A variable air cushion at each end is tuned independently, so faster speeds up to 800 mm/s or heavier loads land gently without metal-to-metal impact. The stop holds position mechanically only; it is not a brake against air loss.
