Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X75-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X75-10S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MACJ40X75-10S
Fine-tuning beats re-machining: the MACJ40X75-10S lets you dial the extend stroke down by as much as 10 mm after installation, while variable air cushions at both ends let you raise cycle speed without bottoming-out bangs. In a 40 mm bore the cylinder is double-acting, with 628.3 N push and 527.8 N pull available at 0.5 MPa, reaching 879.6 N at 0.7 MPa.
Its MA body is a rolling-packed design: the stainless-steel barrel is riveted to the aluminium covers around a stainless block, staying sealed under daily vibration. At 0.15-1.0 MPa (22-145 psi) and 30-800 mm/s on 40 um filtered air, expect about 377 N of practical pushing effort at 0.5 MPa; run it vertically and it lifts a 32 kg load with a 2:1 margin. And because the magnet ships fitted, CMSG / DMSG / EMSG switches mount in minutes.

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 MACJ40X75-10S Is Used
Sheet-metal flanging bench
Pressing a shallow flange into aluminium brackets: 628 N at 0.5 MPa forms light-gauge edges, and the 10 mm trim suits varying bracket heights.
Bottle reject pusher
Nudging off-spec bottles off a rinser discharge conveyor; the cushioned ends take the repeat impacts and the stainless barrel survives the wet zone.
Gripper riser on a pick arm
Lifting a gripper assembly 75 mm between pick stations - roughly 32 kg vertical capability with margin - while a DMSG switch confirms the up position.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X75-10S the Right Cylinder?
Where does the 40 mm fit? One step down, a 25 mm MACJ pushes 245.3 N at 0.5 MPa; one step up, a 63 mm bore delivers 1557.9 N - this model covers clamping and pressing in between. Remember the 10 mm adjuster shortens the extend stroke only and cannot lock the rod in place if the air supply fails. FA flange or LB foot mounting and I / Y knuckles handle most fixture layouts, and with a 75 mm stroke keep side loads off the 16 mm chrome rod to protect the guides.
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 MACJ40X75-10S FAQ
Yes. Double-acting at 0.5 MPa: 628.3 N push, 527.8 N pull. At 0.7 MPa: 879.6 N push, 738.9 N pull. Theoretical maximum at 1.0 MPa is 128.1 kgf. The extend stroke is field-trimmable by up to 10 mm, both ends carry a variable cushion, ports are 1/8 inch, and the 16 mm rod ends in an M12x1.25 thread.
It is not. The stop screw sets where the extend stroke ends; it is a mechanical limit, not a brake, so if pressure drops the piston can drift back. For load holding, add a separate locking solution or keep the air supply up. What the cylinder does give you is a standard built-in magnet for CMSG, DMSG and EMSG position feedback.
