Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-10S
The AirTAC Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-10S 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 MACJ20X175-10S
Small bore, long reach: the MACJ20X175-10S drives 157 N at 0.5 MPa from a 20 mm stainless tube, with the extend stroke settable within a tight 10 mm window for fine end-position tuning. Variable cushions at both ends let you tame the deceleration as loads or speeds change.
The round shell is riveted together - stainless barrel, 20 um hard-chrome rod, aluminium end covers - a build that shrugs off the condensation and mild washdown that rust painted minis. With 157 N rated push, expect about 94 N for real continuous work at 0.5 MPa, or a vertical lift in the region of 8 kg when you keep a 2:1 reserve. The piston magnet comes fitted, so CMSG, DMSG and EMSG switches are drop-on accessories.

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 MACJ20X175-10S Is Used
Index table detent
Holding and releasing a detent pin on a small rotary indexing fixture, with the 10 mm window used to set pin engagement depth precisely.
Cosmetic cap press
Light pressing of pump caps onto cosmetic bottles where only about 94 N of sustained force is needed and stroke end is trimmed within 165-175 mm.
Label sensor flag
Raising a flag that interrupts a photo-eye on a labelling head, confirming label-web position through the built-in magnet and a CMSG switch.
Is the Airtac MACJ Stainless Steel Mini Adjustable Cylinder MACJ20X175-10S the Right Cylinder?
Sizing neighbours: a 16 mm MACJ gives 100.5 N at 0.5 MPa and a 25 mm one gives 245.3 N; this 20 mm bore lands between them at 157 N push. Because the 175 mm stroke is nearly nine times the 8 mm rod diameter, avoid cantilevered side loads - guide the payload or use a Y or I knuckle for pivoted motion.
Choose the FA flange for face mounting or the LB foot for base mounting; both keep the riveted body undrilled. Note that the trim screw locates the extend limit only - it is not a brake, and a lost-air event lets the piston retreat unless the port is blocked or valved.
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 MACJ20X175-10S FAQ
At 0.5 MPa: 157 N extend, 131.9 N retract. At 0.7 MPa: 219.8 N extend, 184.7 N retract. The 1.0 MPa theoretical ceiling is 32 kgf. Operating band is 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), speed 30-800 mm/s.
The riveted body - stainless tube, 20 um hard-chrome carbon-steel rod and aluminium covers - keeps its seal and finish in condensation, washdown splash or outdoor dust where painted and plain aluminium minis pit. The two-way piston seal also retains grease, extending service intervals.
