Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X175-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X175-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MACJ40X175-75S
A riveted stainless round barrel and hard-chrome plated 16 mm rod make this bore 40 MACJ a natural pick for damp or lightly washed-down cells, and at 0.5 MPa it still delivers 628.3 N push and 527.8 N pull. The 75 mm window gives the widest on-site trim in this class: maintenance can shorten the 175 mm extend stroke anywhere in that range, while variable cushions at each end tame decel shock.
Running at 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) filtered air, the double-acting piston carries its magnet as standard equipment, so CMSG, DMSG or EMSG switches drop straight on. As a planning figure, count on roughly 377 N of usable force at 0.5 MPa, enough to hoist about 32 kg vertically once a 2:1 margin is applied.

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 MACJ40X175-75S Is Used
Pallet indexing push
Advances a pallet one station on an assembly conveyor; 628 N at 0.5 MPa nudges loaded pallets and the 75 mm window dials each index in exactly.
Die ejection in a small press
Kicks formed parts out of a shallow die after each stroke, with the variable cushions absorbing the snap at high cycle rates.
Hopper gate open-close
Swings a slide gate under a powder hopper, where the stainless rolled body resists the humid, dusty atmosphere above the discharge.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X175-75S the Right Cylinder?
Step down to a 32 mm bore (402.2 N push at 0.5 MPa) for lighter duty, or up to 50 mm (981.3 N) when the load climbs. If the job only needs fixed travel, the cushioned MAC version skips the adjuster; for two-sided tooling the MACD double-rod variant is worth a look. Keep in mind the stop screw is not a brake: with air removed the piston creeps, so add a locking valve or an external catch for positive holding. Choose FA flange or LB foot mounting, fit I or Y knuckles at the rod, and note the 1/8" ports and M12x1.25 male rod thread.
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 MACJ40X175-75S FAQ
Expect 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, and up to 128.1 kgf theoretical at 1.0 MPa. The 75 mm trim window and 30-800 mm/s speed band sit on top of a 0.15-1.0 MPa (22-145 psi) supply.
The barrel is a rolled stainless tube and the 16 mm rod carries 20 um of hard chrome, so condensation, splash and mild washdown do not chew the body - a common early failure point on coated or painted mini cylinders in food and outdoor settings.
