Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X100-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X100-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 100mm stroke, 1/8" 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 MACJ40X100-10S
When 100 mm of reach needs muscle, this 40 mm MACJ answers with 628 N forward and 528 N back at 0.5 MPa (880 N / 739 N at 0.7 MPa, 128 kgf theoretical max). The -10 window lets you trim the extend stroke up to 10 mm on the machine, and variable cushions at each end keep the approach and return soft. Air at 0.15-1.0 MPa (22-145 psi) drives it at 30-800 mm/s.
The riveted round body pairs a stainless barrel with aluminium covers and a 20 um hard-chrome plated rod, a combo that outlasts painted minis near coolant mist. The magnet is included as standard for CMSG / DMSG / EMSG sensing. As a working number, treat around 377 N at 0.5 MPa as the honest daily push rather than the full 628 N rating.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 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 MACJ40X100-10S Is Used
Roller-conveyor reject pusher
Sweeps off-spec cartons sideways at line speed; 628 N at 0.5 MPa clears a heavy pack easily and the cushion softens every stroke.
Machine-tool chip gate
Opens the access gate on a machining-center chip enclosure; the stainless barrel and chrome-plated rod stand up to coolant mist where painted bodies corrode.
Locating-pin lift
Raises a spring-loaded locating pin with a part load of about 32 kg vertically, the 2:1-margined lift figure derived from this bore's 628 N at 0.5 MPa.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X100-10S the Right Cylinder?
At 100 mm stroke, keep side load off the rod - guide the load externally if it overhangs, because a 16 mm rod under bending at full extension wears seals early. Step up to the 50 mm bore (981 N at 0.5 MPa) for more force or down to the 32 mm (402 N) for less. The -10 adjuster is an extend-side stop that will not hold the load if air is lost, so fit a locking valve where holding matters. Mount FA / LB, knuckles I / Y, 1/8" port.
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 MACJ40X100-10S FAQ
It pushes 628 N and pulls 528 N at 0.5 MPa; at 0.7 MPa that climbs to 880 N push and 739 N pull. Maximum theoretical force is 128 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
No. The screw is an extend-side end stop that trims the stroke; the piston still drifts when pressure is lost, so it must never be treated as a load-holding brake. Use a locking or 3-position valve if the load has to stay put.
