Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X125-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X125-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 125mm 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 MACJ32X125-50S
Fifty millimetres of adjustment makes the MACJ32X125-50S the most flexible of the 32 mm adjustable family: the extend stroke runs anywhere from 75 to 125 mm, set by the external stop screw. Double-acting with a variable cushion at each end, it extends with 402 N at 0.5 MPa (72 psi), comfortably handling gates, pushers and small lifts across the full 30-800 mm/s speed band.
The round stainless barrel and hard-chrome carbon-steel rod take splash, humidity and outdoor exposure in stride, and the rolled aluminium covers keep the riveted body rigid for years. Lift maths for this bore: 402 N at 0.5 MPa equals about 41 kg of vertical pull, so spec roughly 20 kg per lift for a 2:1 margin. Position sensing needs no options - the magnet is built in and pairs with CMSG, DMSG or EMSG switches, while FA flange or LB foot mounting bolts to standard plates.

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 MACJ32X125-50S Is Used
Product pusher on a snack food transfer
One cylinder handles multiple lane widths after the 75-125 mm trim, with 402 N at 0.5 MPa clearing fully loaded belts.
Tooling clamp on a CNC fixture plate
Set clamp travel per fixture within the 50 mm window; the end cushion prevents shock each time the clamp seats.
Box kick-off at a sorter induct station
The stainless barrel shrugs off unconditioned dock air, and about 20 kg of vertical capacity with margin helps divert heavy parcels down chutes.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X125-50S the Right Cylinder?
This 50 mm window suits machines retooled between products often: trim from 125 mm down to 75 mm instead of swapping cylinders. Against the neighbours, a 25 mm MACJ delivers 245 N at 0.5 MPa and a 40 mm bore delivers 628 N; this 32 mm model sits in the middle at 402 N. The stop screw defines the extend limit only and is neither a mid-stroke lock nor a holding brake - under air loss the rod moves freely, so add valving or an external lock where holding matters. Choose FA, LB, I or Y hardware to suit the frame.
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 MACJ32X125-50S FAQ
Extend 402 N and retract 345.6 N at 0.5 MPa (72 psi); extend 563 N and retract 483.8 N at 0.7 MPa (101 psi); 82 kgf theoretical maximum at 1.0 MPa. Speed range is 30-800 mm/s and cushioning is adjustable at both ends.
FA flange and LB foot mount on the rolled body, I and Y knuckles fit the 12 mm rod, and the built-in magnet - standard, not an extra - drives CMSG, DMSG or EMSG switches anywhere along the stainless barrel.
