Airtac MAC Stainless Steel Mini Air Cylinder MAC20X175SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X175SCM is a genuine double acting + 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 MAC Stainless Steel Mini Air Cylinder MAC20X175SCM
A 175 mm reach, a pivoting CM round-end cover and 157 N of push at 0.5 MPa make the MAC20X175SCM a natural for long-throw link arms. Double acting with variable air cushions at each end, it runs 30-800 mm/s on a 0.15-1.0 MPa (22-145 psi) supply and proofs to 1.5 MPa (215 psi).
The round barrel is stainless steel, riveted to aluminium-alloy covers in a rolling-packed joint that will not work loose, and the carbon-steel rod wears 20 um of hard chrome against corrosion. Do the arithmetic once and design with confidence: keep real effort near 94 N for a sound margin, which corresponds to lifting roughly 8 kg vertically.

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 MAC Stainless Steel Mini Air Cylinder MAC20X175SCM Is Used
Stretching station on a bag-making machine
Pulling film edges taut ahead of the seal bar - the 175 mm stroke spreads the web and the adjustable cushion eases the arms home at the end of every cycle.
Roller-gate latch in a picking bay
Swinging a gate latch open at the end of a gravity roller run - the round-end pivot matches the latch lever directly and a DMSG switch reports the locked status back to the WMS.
Connector pusher in a cable test rig
Seating connector modules into a test jig - about 94 N of working force seats the contacts gently, and the chrome rod shrugs off the flux fumes in the enclosure.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X175SCM the Right Cylinder?
If 157 N at 0.5 MPa overshoots the job, a bore 16 barrel gives 100.5 N; if the arm gets heavier, a bore 25 cylinder offers 245.3 N. Note the MAC has no internal lock - centred valve, drifting piston - so hang a pilot check valve or rod lock on any load that must stay raised. The CM round end carries a pivot pin in line with the thrust; FA flange, LB foot or SDB pivot brackets handle fixed points, and the standard magnet pairs with CMSG, DMSG and EMSG switches. Air enters through 1/8" ports on this bore, and external guiding matters at 175 mm: keep side load off the 8 mm chrome rod to protect the bearing and cushion seals.
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 MAC Stainless Steel Mini Air Cylinder MAC20X175SCM FAQ
Push 157 N and pull 131.9 N at 0.5 MPa; push 219.8 N and pull 184.7 N at 0.7 MPa; theoretical maximum 32 kgf at 1.0 MPa. Supply pressure range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure.
No - every MAC20X175SCM includes the magnet as standard, so CMSG, DMSG or EMSG switches snap onto the stainless barrel for end-of-stroke or mid-stroke signalling with no special-order piston required.
