Airtac MAC Stainless Steel Mini Air Cylinder MAC20X75SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X75SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 75mm 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 MAC20X75SCA
Seventy-five millimetres of travel and a pivot-ready back cover make MAC20X75SCA a tidy pick for swinging levers and short-arc linkages. The cylinder is double acting with a variable air cushion at each end, and its 20 mm stainless barrel carries riveted aluminium covers and a hard-chrome plated 8 mm rod. At 0.5 MPa the bore yields 157 N of push.
Count on roughly 94 N of dependable working force at 0.5 MPa - enough to lift about 8 kg vertically once a 2:1 margin is applied. Because the magnet is part of the standard build, position feedback via CMSG, DMSG or EMSG switches costs nothing extra in specification time. Pressure window is 0.15-1.0 MPa (22-145 psi) and the fluid is air filtered to 40 um.

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 MAC20X75SCA Is Used
Lever-arm tensioner
Pulls a spring-loaded idler arm on a textile winding machine through its 75 mm arc, with the cushion damping the release stroke.
Gripper swing on a small cartesian robot
Rotates a light gripper bracket between pick and drop stations, a DMSG switch confirming each end of travel.
Carousel shelf latch release
Unlatches a light shelf lock on vertical carousel storage before the elevator moves, using about 94 N of working push.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X75SCA the Right Cylinder?
One bore down, the bore 16 MAC provides 100.5 N at 0.5 MPa; one bore up, bore 25 reaches 245.3 N. This model cannot hold a load against gravity when air is lost - the piston simply drifts - so pair vertical duty with a rod lock or pilot check valve. The CA back cover pins straight into a swinging linkage, while FA flange, LB foot or SDB pivot brackets handle fixed mounting, and I or Y knuckles close off the rod end.
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 MAC20X75SCA FAQ
Push at 0.5 MPa: 157 N; pull at 0.5 MPa: 131.9 N; push at 0.7 MPa: 219.8 N; pull at 0.7 MPa: 184.7 N; theoretical maximum 32.0 kgf at 1.0 MPa. Stroke is 75 mm on a 20 mm bore with a 1/8" port.
It lets the cylinder swing with a lever or linkage, avoiding side load on the hard-chrome rod. Together with the standard magnet and the 30-800 mm/s speed range, it covers most light push-pull automation without custom brackets.
