Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X25-30S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X25-30S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MACJ32X25-30S
This 32 mm MACJ carries a generous 30 mm adjustment window on a compact 25 mm base stroke, so one cylinder can serve several jig variants. Air drives it in both directions and the variable cushion dials out end-of-stroke shock, letting you push cycle speeds toward the 800 mm/s ceiling without hammering the covers. Rated 402 N push at 0.5 MPa, or 563 N once the supply rises to 0.7 MPa.
Construction is the familiar MA recipe: stainless tube, hard-chrome plated rod, riveted aluminium ends - no tie-rod hardware to work loose in vibration. FA flange or LB foot plates bolt straight on, and I or Y rod knuckles absorb small misalignment.

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 MACJ32X25-30S Is Used
Bench-top pneumatic punch for bracket holes
Punches 2 mm aluminium brackets with 402 N of push, and the trim window lets operators tune punch depth per bracket pattern instead of shimming the die.
Tote-lane divert paddle in a pick module
Swings or pushes totes into a pick lane; cushioned ends keep the paddle from slamming at the high pace of order picking.
Door latch actuator on an oven trolley
The stainless barrel and chrome rod handle radiant heat and humidity near the oven line where painted mini cylinders corrode quickly.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X25-30S the Right Cylinder?
Work the numbers both ways: drop to the 25 mm bore for 245 N at 0.5 MPa or step up to 40 mm for 628 N when the load grows past roughly 240 N of real effort. The 30 mm window absorbs last-minute jig changes; it shortens the extend stroke only and never extends it beyond the ordered 25 mm.
Pick FA flange for plate-mounted fixtures or LB foot for base frames; the built-in magnet keeps CMSG, DMSG and EMSG switch options open without a special order.
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 MACJ32X25-30S FAQ
At 0.5 MPa: 402 N extend and 346 N retract. At 0.7 MPa: 563 N extend and 484 N retract. Maximum theoretical force at 1.0 MPa is 82 kgf. Proof pressure is 1.5 MPa (215 psi) against an operating band of 0.15-1.0 MPa (22-145 psi), with speeds of 30-800 mm/s.
The 32 mm bore carries a 12 mm hard-chrome rod with M10x1.25 male thread and 1/8 in air ports on both covers. Port thread options are PT (blank code), G or NPT. Mounting choices are FA flange and LB foot, with I or Y rod knuckles available for the rod side.
