Airtac MAC Stainless Steel Mini Air Cylinder MAC20X165SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X165SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 165mm 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 MAC20X165SCA
Pivot-mount duty is where the MAC20X165SCA fits best: the CA back cover gives a rear pivot point, so linkages and swing arms connect without extra hardware. This 20 mm double-acting mini cylinder develops 157 N push and 132 N pull at 0.5 MPa, reaching 220 N push at 0.7 MPa, while the variable air cushion at both ends dials out the shock of a fast-return arm at up to 800 mm/s.
Air comes in at 0.15-1.0 MPa (22-145 psi) through 1/8" ports, and the riveted stainless barrel with its hard-chrome rod stands up to splash and humidity that shorten the life of painted minis. For planning, expect roughly 94 N of honest working force at 0.5 MPa - enough to swing or lift about 8 kg vertically with a comfortable 2:1 margin.

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 MAC20X165SCA Is Used
Lid swing arm on a mix tank
Pivot the CA cover to a lever arm that swings a small tank lid open; the 165 mm stroke sets a wide, repeatable arc.
Hopper gate damper
Open and close a slide gate under a small ingredient hopper - 157 N at 0.5 MPa handles light granular product through a linkage.
Web tension lay-on roller
Lift a lay-on roller against a film web using the push side, cushioned at both ends so the roller never slams home.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X165SCA the Right Cylinder?
Compare bores on real numbers: a 16 mm unit manages 100 N push at 0.5 MPa, this 20 mm bore 157 N, and a 25 mm bore 245 N - pick the smallest that clears your load with margin. With the driven linkage pivoting on the CA cover, keep side thrust off the 8 mm rod over the 165 mm stroke to protect it from bending. Air loss leaves the piston unheld, so a suspended arm needs a pilot check valve or rod lock; the standard magnet means CMSG, DMSG or EMSG switches bolt on whenever position feedback is wanted.
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 MAC20X165SCA FAQ
At 0.5 MPa: 157 N push, 132 N pull. At 0.7 MPa: 220 N push, 185 N pull. Theoretical ceiling is 32 kgf at 1.0 MPa. Supply pressure spans 0.15-1.0 MPa (22-145 psi), speed runs 30-800 mm/s, ports are 1/8", and the rod thread is M8x1.25.
Needle screws sit in each cover: unscrew them fully before first run, then close gradually while cycling until end-of-stroke noise fades. The cushion is variable air, not a mechanical stop or a brake - the rod still drifts if air is lost.
