Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X160-20S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X160-20S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø32mm bore and 160mm 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 MACJ32X160-20S
Adjustability is the selling point here: the MACJ32X160-20S trims its 160 mm extend stroke by up to 20 mm with an external stop screw, so one cylinder covers several product heights on the same machine. Air works both ways (double-acting) and variable cushions at each end absorb the last of the shock, letting you run 30-800 mm/s without hammering the aluminium covers. At 0.5 MPa the bore 32 piston delivers 402 N forward and 346 N back.
Vertically this rod can lift about 41 kg at 0.5 MPa; keep around 20 kg for a comfortable 2:1 margin on real lifts. The riveted stainless barrel with hard-chrome carbon-steel rod tolerates humidity and light washdown far better than painted minis, and the standard magnet pairs with CMSG, DMSG and EMSG switches. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.

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 MACJ32X160-20S Is Used
Glue-head depth setting
Set glue bead depth on a carton erecting machine; the 20 mm window compensates for different flap heights without changing cylinders.
Fixture clamp
Clamp aluminium extrusions on a CNC fixture; 402 N of hold at 0.5 MPa with the 20 mm trim matching part-to-part variation.
Palletizer infeed squaring
Square cartons on a palletizing infeed; the variable cushion stops the 160 mm stroke from jolting the stack.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ32X160-20S the Right Cylinder?
For sizing, compare neighbours honestly: 245 N from a 25 mm bore or 628 N from a 40 mm bore at 0.5 MPa bracket the 402 N this cylinder delivers, and pull force drops to 346 N because the rod steals piston area. If you need the rod held at a set point, remember the adjuster is a mechanical stop for the extend direction only - it does not lock position when air is lost.
Choose FA flange or LB foot mounting, add an I or Y knuckle where the load pivots, and let the built-in magnet drive CMSG or EMSG feedback with no special-order piston.
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 MACJ32X160-20S FAQ
Push is 402.2 N and pull 345.6 N at 0.5 MPa; at 0.7 MPa expect 563.0 N push and 483.8 N pull, with 82 kgf theoretical maximum at 1.0 MPa. The air port is 1/8", the 12 mm rod carries an M10x1.25 thread, and the stop screw trims extend travel up to 20 mm.
No. Every MA-series cylinder including this one ships with the magnet built in as standard, so CMSG, DMSG or EMSG switches drop straight onto the barrel for end-of-stroke or position feedback.
