Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 225mm 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 MACJ32X225-30S
A 32 mm bore in the MA round-body range gives you 402 N of push at 0.5 MPa, and the MACJ32X225-30S wraps that force in a 225 mm stroke whose extend position can be re-set on site anywhere inside a 30 mm window. The external stop screw only shortens the extend stroke - it never lengthens it - and a variable air cushion at each end soaks up the shock when the piston lands. Running on filtered air at 0.15-1.0 MPa (22-145 psi) and speeds of 30-800 mm/s, it suits fast pick-and-place cycles.
Build quality is where this mini earns its keep: a stainless barrel riveted to aluminium-alloy covers shrugs off washdown and damp better than painted minis, the hard-chrome plated rod resists scoring, and the piston seal stores its own grease. Every unit ships with a built-in magnet, so CMSG, DMSG or EMSG switches clip on without a special order. At 0.6 of the rated push, plan on roughly 241 N of real work; the full 402 N equates to about 41 kg, so halving for a 2:1 margin lets you lift about 20 kg vertically.

Where the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-30S Is Used
Fixture stop fine-tune
Positions an assembly fixture stop on an automotive bracket line, where the 30 mm window absorbs part-to-part tolerance drift without swapping cylinders.
Carton divert pusher
Diverts cartons on a bakery conveyor - the 402 N push carries roughly 20 kg of vertical-equivalent load with margin, and the dual cushions silence every hit.
Sample tray elevator
Raises sample trays in a laboratory autoclave loader; the stainless barrel tolerates steam-humid air that corrodes painted mini cylinders.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X225-30S the Right Cylinder?
Compare both directions before you commit: a 25 mm bore MACJ gives only 245 N push at 0.5 MPa, while stepping up to 40 mm buys 628 N, so the 32 mm frame at 402 N sits squarely in the middle for 225 mm travels. If your job is mainly holding a position against gravity rather than adjusting a stroke, a mid-stroke lock or external stop is the right tool - the MACJ adjuster just sets the extend end point. FA flange or LB foot mounts, plus I and Y rod knuckles, cover most fixtures, and the magnet is already in the piston.
At 225 mm of travel, side loads become the main rod-killer: guide the load externally and keep the thrust close to axial. With about 241 N usable at 0.5 MPa, this cylinder comfortably carries jigs, small gates or grippers in that band.
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 MACJ32X225-30S FAQ
At 0.5 MPa it pushes 402 N and pulls 346 N; at 0.7 MPa that rises to 563 N push and 484 N pull. The theoretical maximum at 1.0 MPa is 82 kgf. Real continuous work should stay near 241 N, and the full 402 N equates to lifting about 41 kg, or about 20 kg with a 2:1 safety margin.
The -30 suffix sets a 30 mm window: an external stop screw shortens the 225 mm extend stroke to any point inside that range, and a variable air cushion at each end absorbs landing shock. The adjuster is an extend-side stop, not a load-holding brake - on air loss the piston still drifts. Supply runs 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s with 1/8" ports.
