Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø20mm 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 MACJ20X160-75S
When the job might change - a fixed-stroke MAC for a simpler build, an MAJ bumper version, or a MACD double-rod unit - the MACJ20X160-75S covers the adjustable middle ground with the widest trim of this run: 75 mm of on-site stroke adjustment inside the ordered 160 mm. It is double-acting, variably cushioned at both ends, and develops 157 N at 0.5 MPa (219.8 N at 0.7 MPa).
Derating to about 94 N of working push at 0.5 MPa leaves margin for seal drag and pressure dips, which matters on a 160 mm stroke where a stalled load still sees the full air column. Stainless barrel, chrome-plated rod, riveted aluminium covers, and a standard magnet that reads on CMSG, DMSG and EMSG switches without a special-order piston round out the package.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MACJ20X160-75S Is Used
Parcel diverter pusher
Kicking small parcels across a sorting belt: 94 N of derated push moves a 2 kg parcel with margin, the 75 mm window suits mixed parcel heights, and a CMSG switch confirms the pusher is home between kicks.
Label head retract
Retracting an applicator head on a labeling machine between product sizes - maintenance resets the extend stop anywhere in 75 mm without swapping cylinders, and the chrome rod wipes clean in a tacky label zone.
Fixture clamp reset
Clamping wooden drawer parts in a furniture jig where batch changeovers move the clamp face: the wide 75 mm range absorbs new fixture positions, and the two-end cushion keeps the clamp from slamming into the jig.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X160-75S the Right Cylinder?
Start from the load: at 0.5 MPa bore 20 gives 157 N push and 131.9 N pull, bore 16 gives 100.5 N and bore 25 gives 245.3 N - pick whichever bracket fits with margin. On this 160 mm stroke keep guides external so the 8 mm rod sees axial force only. The 75 mm window is generous enough to re-target the extend stop between product changeovers. Choose FA flange or LB foot mounting, add I or Y knuckles for linkages, and remember the stop screw limits travel without locking the piston when supply pressure drops.
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 MACJ20X160-75S FAQ
At 0.5 MPa: 157 N push, 131.9 N pull. At 0.7 MPa: 219.8 N push, 184.7 N pull. Theoretical ceiling at 1.0 MPa is 32.0 kgf. Bore 20 mm, 8 mm rod, 1/8" port, M8x1.25 male rod thread, 160 mm stroke adjustable over 75 mm, speed 30-800 mm/s, air supply 0.15-1.0 MPa (22-145 psi), fluid filtered to 40 um.
Pick an FA flange for face bolting or an LB foot for base mounting, and add I or Y rod knuckles where the linkage needs a swivel. The extend stop screw is reset with a wrench anywhere in the 75 mm window. It is a travel limit only - not a load-holding brake - so support the load with valves or external stops when air is removed.
