Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 175mm 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 MACJ32X175-20S
Two centimetres of on-machine stroke trim is usually all a fixture needs, and the MACJ32X175-20S provides exactly that: a 20 mm window over its 175 mm nominal extend stroke, with variable air cushions each end to kill residual shock. It runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s.
In this bore the cylinder makes 402 N push and 346 N pull at 0.5 MPa, the force class of a small staking or ejecting head. The riveted stainless round barrel handles humid and food-adjacent areas, and the magnet comes fitted as standard, so CMSG, DMSG or EMSG switches bolt on for end-of-stroke signals. Keep continuous work near 241 N at 0.5 MPa and the 32 mm bore stays in its comfort zone.

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 MACJ32X175-20S Is Used
Small staking head
Drives a light staking or marking head over sheet-metal brackets; the cushions land the head without denting the marking die.
Tote ejector on pick module
Pushes picked totes off a shelf edge into a takeaway conveyor, with the 20 mm trim matched to the tote stop geometry.
Pop-up roller section
Raises a pop-up roller section in a staging area so cartons change direction; the magnet feeds position signals via CMSG or DMSG switches to the controller.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X175-20S the Right Cylinder?
Step down to bore 25 (245 N push at 0.5 MPa) for light clamps or up to bore 40 (628 N) when 32 mm feels marginal - all share the MA round-body build. The 20 mm stop screw shortens extend travel only and will not lock position if air is lost, so plan an external stop for suspended loads. Mount via FA flange or LB foot and pick I or Y knuckles where the load pivots; with 175 mm of stroke, align couplings carefully to limit bending on the 12 mm chrome rod.
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 MACJ32X175-20S FAQ
Push 402 N and pull 346 N at 0.5 MPa; push 563 N and pull 484 N at 0.7 MPa; 82 kgf theoretical maximum at 1.0 MPa. Stroke adjusts within a 20 mm window, cushioning is variable at both ends, speed is 30-800 mm/s, and proof pressure is 1.5 MPa (215 psi) with 1/8 inch ports.
The barrel is stainless steel rolled onto aluminium-alloy covers with a stainless block, and the 12 mm rod is hard-chrome plated to 20 um. That combination tolerates humid air, splash and periodic washdown far better than painted-steel mini cylinders, though it is not rated for aggressive chemical media.
