Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-50S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-50S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 100mm 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 MACJ32X100-50S
Heavy small-part handling is the home turf of the MACJ32X100-50S: a double-acting 32 mm mini cylinder whose extend stroke can be cut back anywhere inside a 50 mm window, with a variable air cushion at each end to calm fast stops. At 0.5 MPa it pushes 402 N and retracts with 345.6 N.
Construction is a stainless-steel barrel riveted to aluminium-alloy covers around a hard-chrome plated 12 mm rod - a rolled round body that laughs at damp workshops. The piston magnet is fitted as standard equipment for CMSG, DMSG or ESG switches, no upcharge. For sizing, treat about 241 N as your working push at 0.5 MPa; halved again for lifting duty that is roughly 20 kg of vertical load with margin built in.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
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 MACJ32X100-50S Is Used
Ejector on a small stamping press
Kicks finished blanks off a compact press die; 402 N at 0.5 MPa clears oiled parts at stroke rates the 30-800 mm/s range easily covers.
Height gate on a bakery depositor
Sets batter tray clearance on a depositor line; the 50 mm window is tuned per recipe during morning changeover.
Diverter on a parcel sorter
Pushes small parcels onto a spur from the main belt; dual cushions let the diverter run fast without shaking the frame.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X100-50S the Right Cylinder?
Compare against the smaller 25 mm bore (245.3 N push at 0.5 MPa) or the larger 40 mm bore (628.3 N push at 0.5 MPa) to confirm 32 mm is the right force step. With 50 mm of trim available, the end stop sees real side thrust on off-centre loads - keep the rod square to the load or add a guide. The stop shortens extend stroke only and is not a load lock when air fails. FA and LB mounts, I and Y knuckles, magnet included.
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 MACJ32X100-50S FAQ
Push 402.2 N and pull 345.6 N at 0.5 MPa; push 563.0 N and pull 483.8 N at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Port is 1/8", rod thread M10x1.25, operating band 0.15-1.0 MPa (22-145 psi), temperature -20 to +70 C.
The stainless barrel with hard-chrome plated rod resists corrosion and washdown, and the riveted cover design keeps the seal reliable without tie-rod maintenance. Combined with the 50 mm on-site stroke trim, one cylinder covers what would otherwise need several fixed-stroke units.
