Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X500-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X500-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 500mm 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 MACJ32X500-20S
Long travel in a compact round body: the MACJ32X500-20S reaches 500 mm - the maximum standard stroke for this bore - while still carrying a 20 mm extend-trim window and two-sided variable air cushion for controlled deceleration over the full run.
Stainless barrel, riveted aluminium covers and a 20 um hard-chrome rod let it live on damp plant floors and near washdown zones without flaking paint or corroded seams. Output is 402 N push / 346 N pull at 0.5 MPa, enough to lift about 41 kg straight up at full pressure, or roughly 20 kg at a 2:1 safety margin. Built-in magnet for CMSG / DMSG / EMSG switches, 30-800 mm/s, 0.15-1.0 MPa (22-145 psi).

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 MACJ32X500-20S Is Used
Guard door actuation
Slide an interlocked machine-guard door through its full 500 mm travel, with the cushion easing the latch home at each close.
Cross-belt pusher
Sweep cartons from a wide accumulation conveyor into a takeaway lane; external guides carry the side load the long rod cannot.
Tray-stack lifter
Raise a tier of small trays in a dispensing cabinet; at a 2:1 margin the bore handles about 20 kg reliably.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X500-20S the Right Cylinder?
If 402 N at 0.5 MPa overshoots, a 25 mm bore gives 245 N; if you need more, a 40 mm bore pushes 628 N. At 500 mm the slender 12 mm rod becomes side-load sensitive - guide the load externally or use an I or Y knuckle so bending never loads the seals. Note the adjuster only sets the extend endpoint; it will not hold a suspended load if air pressure drops. FA flange or LB foot mounting, magnet standard for CMSG / DMSG / EMSG switches.
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 MACJ32X500-20S FAQ
0.5 MPa: 402 N push, 346 N pull. 0.7 MPa: 563 N push, 484 N pull. Theoretical peak 82 kgf at 1.0 MPa. Stroke 500 mm (maximum standard for bore 32) with a 20 mm adjust window, 12 mm rod threaded M10x1.25, 1/8" ports, pressure 0.15-1.0 MPa (22-145 psi), speed 30-800 mm/s.
Yes - keep side loads off the rod. The stainless round barrel and hard-chrome surface resist corrosion over its full length, but a 500 mm slender rod will bow under off-axis force, so guide the payload linearly or fit a rod knuckle. Both-end cushioning then handles the deceleration cleanly.
