Airtac MAC Stainless Steel Mini Air Cylinder MAC20X125SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X125SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 125mm 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 MAC20X125SCA
The AirTAC MAC20X125SCA pairs a 20 mm bore with a 125 mm stroke in a riveted round body: stainless barrel, hard-chrome plated rod and aluminium covers rolled into one sealed unit. That stainless-plus-chrome build tolerates washdown and damp air far better than painted-steel minis, and the variable air cushion at both ends lets you trim end-of-stroke shock with the needle screws instead of slowing the whole cycle.
At 0.5 MPa the bore pushes 157 N and pulls 132 N; at 0.7 MPa that rises to 220 N, with a theoretical ceiling of 32 kgf. In practice, budget around 94 N of real working force so the cylinder is never running flat out - roughly the push needed to seat a snap-fit cover or kick a light carton off a belt. Speed range is 30-800 mm/s over a 0.15-1.0 MPa (22-145 psi) supply.

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 MAC20X125SCA Is Used
Pick-and-place swing arm
Pivots a suction head between a small-parts feeder and an assembly jig over the 125 mm stroke, cushioned so the head settles without bounce.
Tilting bottle divert gate
Tips a gate on a bottling line so bottles route to the filler or the reject chute, with 157 N at 0.5 MPa ample for a lightweight flap.
Fixture latch actuator
Flips a toggle latch on a machining fixture, the CA pivot cover lining up with the linkage without extra brackets.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X125SCA the Right Cylinder?
If 157 N at 0.5 MPa is more than the job needs, the 16 mm bore MAC still delivers 100 N; if the load grows, step up to the 25 mm bore for 245 N. Note that a MAC does not park the rod when air is lost - it drifts - so fit a pilot check valve or rod lock for held loads. The CA pivot back cover suits swinging linkages directly, and because the magnet is built in as standard, CMSG, DMSG or EMSG switches mount on without a special piston. Over a 125 mm stroke, keep side load off the 8 mm rod with an external guide.
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 MAC20X125SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 132 N; at 0.7 MPa, 220 N push and 185 N pull; the theoretical maximum is 32 kgf. The cushion is variable at both ends and the 125 mm stroke is a standard length.
No. The magnet comes fitted as standard, so CMSG, DMSG or EMSG switches clamp straight onto the barrel for end-of-stroke or mid-stroke signalling.
