Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MACJ40X160-40S
Set the end of travel wherever the fixture needs it: the MACJ40X160-40S trims its extend stroke by up to 40 mm below the ordered 160 mm (down to 120 mm effective) via an external screw, while a variable cushion absorbs deceleration at both ends. The 40 mm bore delivers 628 N push and 528 N pull at 0.5 MPa - in vertical terms that is roughly 64 kgf, or about 32 kg lifted with a 2:1 safety margin.
Its rolling-packed stainless barrel with a hard-chrome 16 mm rod copes with coolant mist and outdoor damp, an advantage over coated mini bodies. The piston magnet is part of the standard build, so DMSG or EMSG switches mount without special ordering.

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 MACJ40X160-40S Is Used
Lab batching station
Dispense nozzles stroke precisely into beakers of varying depth using the 120-160 mm trim range; cushions stop splashing when cycles run fast.
Carton flap tucking
Roughly 377 N of working push folds heavy double-wall flaps on a cartoner, and the tuned cushion keeps each fold from slamming home.
Position-verified gating
A DMSG switch riding on the standard magnet confirms the gate is fully seated before the next station on the line indexes.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-40S the Right Cylinder?
Compare forces before fixing on 40 mm: the 25 mm bore gives 245 N at 0.5 MPa and the 50 mm bore 981 N, so mid-range loads fit this size well. Remember the adjuster only shortens extend travel and does not clamp the piston - it is not a load lock if air pressure fails. FA flange and LB foot mounts suit fixed frames; add I or Y knuckles for pivoting links. Over 160 mm of stroke, guide any side load externally to protect the rod bearings.
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 MACJ40X160-40S FAQ
At 0.5 MPa: 628 N push and 528 N pull. At 0.7 MPa: 880 N push and 739 N pull. The theoretical maximum is 128.1 kgf at 1.0 MPa. Speed range is 30-800 mm/s and pressure runs 0.15-1.0 MPa (22-145 psi), with proof at 1.5 MPa (215 psi).
An FA flange or LB foot bolts the round body to the frame, and I or Y rod knuckles suit pivoting linkage. The stroke adjuster is a hard stop for the extend direction only - never use it as a brake against a hanging or suspended load.
