Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X210-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X210-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 210mm 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 MACJ32X210-30S
A compact 32 mm bore actuator built for on-site stroke tuning, the MACJ32X210-30S is double-acting with a variable air cushion at each end and a 30 mm window for trimming the extend stroke. Push force reaches 402 N at 0.5 MPa (and 563 N at 0.7 MPa), while the riveted stainless round barrel and 12 mm hard-chrome plated rod shrug off the splash and humidity that wreck painted mini cylinders in food plants.
Practically, that 402 N rating means you should plan on roughly 241 N of usable work at 0.5 MPa once you derate for real conditions. A built-in magnet is standard, so CMSG, DMSG or EMSG switches mount without a special piston. Air supply runs 0.15-1.0 MPa (22-145 psi) with speeds from 30-800 mm/s.

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 MACJ32X210-30S Is Used
Connector staking press
A light benchtop staking head on 210 mm travel gets 402 N of push at 0.5 MPa, and the 30 mm trim window lets the operator dial the cradle depth down to the exact die position.
Bottle-line reject gate
Stainless barrel and chrome rod survive constant washdown on a juice line while the dual cushions stop gate slam at high line speeds.
Glue-bead dispense stop
Dosing nozzles retract to a fixed home position trimmed within 30 mm; the built-in magnet plus an EMSG switch confirms the retracted spot before each bead.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X210-30S the Right Cylinder?
Next bore down is the 25 mm MACJ at 245 N push; next up the 40 mm at 628 N, so step to 40 mm if your 210 mm travel carries near the top of the 32 mm class. The stop screw is an extend-stroke end stop only - with air off the piston can still drift, so do not treat it as a load lock. Mount with an FA flange or LB foot, add I or Y rod knuckles where tooling needs a swivel, and keep side loads off the 12 mm rod over this travel or guide the load externally.
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 MACJ32X210-30S FAQ
At 0.5 MPa it pushes 402 N and pulls 345.6 N; at 0.7 MPa that rises to 563 N push and 483.8 N pull. The theoretical ceiling for the 32 mm bore is 82 kgf at 1.0 MPa. Air supply is 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
An external stop screw shortens the extend stroke anywhere inside the ordered 30 mm window; it cannot lengthen travel beyond the 210 mm nominal stroke. The stop sets an end position only - with air lost the rod still drifts, so it is not a mid-stroke lock or brake. A variable air cushion at both ends absorbs the remaining shock.
