Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-10S 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 MACJ40X160-10S
Fine position trimming is the reason this cylinder exists: the MACJ40X160-10S keeps the full 160 mm travel but lets a technician take up exactly the last 10 mm of extend stroke with a stop screw, so fixture tolerances are absorbed on site instead of by re-ordering. It is double-acting with a variable air cushion at both ends, pushing 628 N and pulling 528 N at 0.5 MPa within a 0.15-1.0 MPa (22-145 psi) band.
The construction earns its keep in wet corners of a plant: a stainless-steel barrel rolled to riveted aluminium covers with a hard-chrome plated rod shrugs off splashes and humid air that pit ordinary mini bodies. Work the mechanism at up to 377 N of sustained effort at 0.5 MPa, or vertically about 32 kg with a 2:1 margin, and clip a CMSG, DMSG or EMSG switch to the standard magnet for end-of-travel confirmation.

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 MACJ40X160-10S Is Used
Analyzer sample drawer
Drives a lab instrument's sample drawer where the 10 mm trim aligns the drawer home position to the optics after service swaps.
Filling nozzle depth set
Positions liquid-filling nozzles into bottle necks; the fine window lets a technician match nozzle drop to a new bottle height in minutes.
Optical inspection fixture stop
Sets a hard repeatability stop on a camera inspection fixture, absorbing lens-stack tolerance without shimming the bracket.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ40X160-10S the Right Cylinder?
A 10 mm window suits tooling that is already close to final geometry - if you expect repeated re-gauging, the 20 mm or 75 mm versions of this same 40 mm bore are the better fit, while bore 32 (402 N) or bore 50 (981 N) bracket the force class. Remember the screw sets an extend-side end stop only: it will not pin the rod against a heavy load when pressure falls, so combine it with air trapping or a hard stop for holding. Choose FA flange or LB foot mounting and I or Y rod knuckles; for the 160 mm stroke, guide any lateral force outside the cylinder.
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 MACJ40X160-10S FAQ
At 0.5 MPa: 628 N push, 528 N pull. At 0.7 MPa: 880 N push, 739 N pull. Maximum theoretical force is 128 kgf at 1.0 MPa. Supply is 0.15-1.0 MPa (22-145 psi) air filtered to 40 um, at 30-800 mm/s through a 1/8" port.
The barrel is stainless steel rolled onto the covers with the piston rod hard-chrome plated to 20 um, so coolant mist, washdown splash and outdoor humidity do not creep under a coating and lift it - a common failure point on painted or anodized mini cylinders in the same size class.
