Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X175-40S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X175-40S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø16mm bore and 175mm stroke, M5×0.8 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 MACJ16X175-40S
Maximum trim flexibility in this bore size: a 40 mm window means the extend stroke on this 175 mm MACJ can be wound anywhere from 135 mm to the full 175 mm without changing parts. Output sits at 100.5 N push / 86.4 N pull at 0.5 MPa (140.7 N / 120.9 N at 0.7 MPa) - plan work around 60 N and the rod still carries a 5 kg vertical lift at half rating.
Nothing here is a tie-rod or extruded profile: the stainless tube, aluminium covers and stainless block are rolled together into one sealed body, with the carbon-steel rod hard-chrome plated to 20 um. Variable air cushions at both ends tame end-of-stroke shock, and the standard-fit magnet pairs with CMSG, DMSG and EMSG switches.

Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 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 MACJ16X175-40S Is Used
Tray denesting head
Lifting the top PET tray from a stack on a packing bench - the 5 kg-class vertical margin and 135-175 mm stroke window cover shallow and deep stacks alike.
Label applicator press pad
Pressing labels onto curved glass bottles on a small bottling line, with the cushioned stop protecting glassware at full line speed.
Test rig actuator
Applying a repeatable light press force to switches and connectors on a QC test bench, re-ranged quickly via the 40 mm trim band.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ16X175-40S the Right Cylinder?
Against the same 0.5 MPa benchmark: 100.5 N here versus 157 N for a 20 mm bore and 245.3 N at 25 mm - size up the moment your load nears 60 N of real work. Plumbing is M5x0.8; mounting runs FA flange, LB foot, I or Y knuckle. On a 175 mm stroke keep side load low or add an external guide, because the 6 mm rod is happiest under pure axial force. Supply 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
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 MACJ16X175-40S FAQ
At 0.5 MPa: 100.5 N extend, 86.4 N retract. At 0.7 MPa: 140.7 N extend, 120.9 N retract. Theoretical maximum at 1.0 MPa: 20.5 kgf. The 16 mm bore has a 6 mm rod, M5x0.8 port and M6x1.0 male thread, an adjustable extend stroke over a 40 mm band with variable cushions, running 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
No. The stop screw only limits extend travel inside the 40 mm window; it is not a mid-stroke lock. With air removed the piston will drift, so pair the MACJ with a separate clamping unit if your process must hold position safely.
