Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-75S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-75S is a genuine double acting, adjustable stroke + cushion standard round-body mini air cylinder with a Ø20mm 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 MACJ20X175-75S
With the widest window in this set - a 75 mm adjustable range on a 175 mm stroke - this double-acting MACJ covers everything from short jigging moves up to full travel, and the twin variable cushions absorb the stop at whichever end you set. The 20 mm bore makes 157 N pushing and 131.9 N pulling at 0.5 MPa.
Its stainless round barrel with a hard-chrome plated rod shrugs off splashes and humidity, an edge over painted minis in food or outdoor spots. No piston option is needed for sensing: the magnet is standard and drops onto CMSG / DMSG / EMSG switches. Halving the 16 kg vertical equivalent of the 0.5 MPa thrust leaves a comfortable 8 kg lift per cylinder for real part weights.

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 MACJ20X175-75S Is Used
Lift-pin release
Raises locating pins out of pallet nests in a machining cell, using the 75 mm trim to match nest depth across part families.
Pick-station indexing
Advances tote stops at a pick station, trimming travel by up to 75 mm as SKU sizes change through the shift.
Hopper gate opening
Cracks open a small ingredient hopper gate on a batching rig; the stainless barrel stands up to washdown between batches.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-75S the Right Cylinder?
Against its neighbours: the 16 mm bore pushes 100.5 N and the 25 mm bore 245.3 N at 0.5 MPa - pick those if 157 N is clearly over or under your load. Sensing is simple because the magnet is built in, and FA / LB mounts plus I / Y knuckles bolt onto typical small fixtures. Long 175 mm strokes on an 8 mm rod want careful alignment to avoid rod bending, and the end-stop adjuster is only a stroke limiter, never a device that holds load.
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 MACJ20X175-75S FAQ
Double-acting output at 0.5 MPa is 157 N forward and 131.9 N backward, climbing to 219.8 N and 184.7 N at 0.7 MPa, with a 32 kgf theoretical maximum at 1.0 MPa. Run it on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s.
FA flange and LB foot brackets are available, with I and Y rod knuckles for pivoting loads; the adjustable version has no SDB or back-cover code. To set the extend stroke, back off the external stop screw anywhere inside the 75 mm window - travel can only be shortened from 175 mm, and the stop is a limiter rather than a lock against drift when air pressure drops.
