Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X200-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X200-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 200mm 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 MACJ32X200-30S
A stainless round barrel riveted to aluminium covers gives the MACJ32X200-30S a washdown-friendly body that painted mini cylinders cannot match, while the hard-chrome plated 12 mm rod resists corrosion in damp plants. This version is double-acting with an adjustable extend stroke: the external stop screw trims the extend anywhere inside the ordered 30 mm window, and a variable air cushion at each end soaks up end-of-stroke shock.
At 0.5 MPa the 32 mm bore delivers 402 N of push and 346 N of pull; treat about 241 N as the practical working force so the cylinder is not running flat out. Every MA cylinder carries a built-in magnet, so CMSG / DMSG / EMSG switches clip on without a special piston. Pressure range is 0.15-1.0 MPa (22-145 psi) and speed runs 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 MACJ32X200-30S Is Used
Carton ejector on a case packer
The 30 mm trim window lets the push stroke be matched exactly to carton height, ejecting 5 kg cases with the 402 N force at 0.5 MPa without slamming the discharge plate.
Reagent vial rack lifter in a filling line
A 200 mm lift with fine stroke trimming raises vial racks between wash and fill stations; the stainless barrel tolerates routine wipe-down in the lab area.
Product pusher on a conveyor diverter
Mounted LB-foot to the frame, the cylinder diverts boxes at the transfer point; end-of-stroke air cushions keep the pusher plate from banging even at 0.7 MPa line pressure.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X200-30S the Right Cylinder?
At 402 N push at 0.5 MPa this bore sits between the 25 mm MA (245 N) and the 40 mm MA (628 N); drop to 25 if your load is light, step up to 40 when you need margin. The stop screw is a mechanical end stop for the extend stroke, not a mid-stroke lock - if air is lost the rod will still drift, so add a locking valve or external stop where holding matters.
Mount with the FA flange or LB foot, or fit an I or Y rod knuckle for pivoting loads. The 200 mm stroke is well inside the 500 mm standard limit for this bore, so no made-to-order barrel is needed.
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 MACJ32X200-30S FAQ
At 0.5 MPa it pushes 402 N (402.2 N exact) and pulls 346 N (345.6 N); at 0.7 MPa that rises to 563 N push and 484 N pull, with a theoretical maximum of 82 kgf at 1.0 MPa. The extend stroke is adjustable within a 30 mm window via the external stop screw, and a variable air cushion works at both ends.
Yes. Every MA-series cylinder, this one included, ships with a magnet in the piston as standard, so CMSG, DMSG and EMSG switches clip straight onto the stainless barrel for end-of-stroke or mid-travel signalling - no special-order piston needed.
