Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm 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 MACJ32X175-50S
A 50 mm band of adjustment under the 175 mm stroke gives this model the widest on-site flexibility in the mid-window range: one cylinder, one plumbing job, several different stop positions. It is double acting with a variable air cushion at both ends, rated 402.2 N push and 345.6 N pull at 0.5 MPa from its 32 mm bore. Construction is the MA series signature: a high-precision stainless tube rolled onto aluminium covers with a hard-chrome plated carbon-steel rod and a two-way piston seal that holds its own grease. In numbers you can quote to a customer: the rod will raise about 41 kg vertically at 0.5 MPa, and staying under roughly 241 N of continuous work keeps you comfortably inside the rating.
The trim stop shortens extension only - it cannot add travel past the ordered stroke, and it will not hold position if air is lost, so treat it purely as a mechanical limit. The magnet is factory standard for CMSG / DMSG / EMSG switches. Ports are 1/8 inch on this bore, PT by default with G or NPT thread on request.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 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 MACJ32X175-50S Is Used
Shuttle stop pin
A stop pin indexing totes on a mini storage shuttle, re-set within the 50 mm window as tote heights change between product lines.
Clamp on a CNC fixture plate
Push clamping of aluminium blanks: 402 N at 0.5 MPa holds light parts, and the 175 mm reach clears the spindle envelope.
Bench-top stake press
Staking terminals onto small connectors where the 50 mm band lets one press serve several terminal heights without shimming.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-50S the Right Cylinder?
Below this model, the 25 mm bore delivers 245.3 N push at 0.5 MPa for lighter gates and chutes; above it, the 40 mm bore reaches 628.3 N push when a heavier fixture needs shifting. The 50 mm adjust window suits machines that get re-tooled between runs. With a 12 mm rod over 175 mm, avoid side loading - guide the load externally on longer travels. The adjustable version has no SDB or back-cover mounting code, so pick FA flange or LB foot instead, with I or Y rod knuckles for the rod end.
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 MACJ32X175-50S FAQ
Here is the full set for the 32 mm bore: 402.2 N push and 345.6 N pull at 0.5 MPa; 563.0 N push and 483.8 N pull at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Operating range 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Because the stop position changes, arrival shock would otherwise vary too. The variable air cushion at each end is tuned on the machine, so whether the stop sits 5 mm or 50 mm into the window the last part of travel is decelerated smoothly instead of hammering the riveted cover.
