Airtac MAC Stainless Steel Mini Air Cylinder MAC50X135SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X135SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 135mm stroke, 1/4" 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 MAC50X135SCA
The MAC50X135SCA is a 50 mm bore, 135 mm stroke round-body mini cylinder from AirTAC's MA family - double acting, so air drives the rod both out and back, with a variable air cushion at each end that you tune to kill end-of-stroke shock. A stainless-steel barrel, hard-chrome plated 20 um carbon-steel rod and riveted aluminium-alloy covers give it real corrosion resistance in damp, washed-down or outdoor spots where painted minis fail. At 0.5 MPa it pushes 981 N and pulls 881 N, climbing to 1374 N at 0.7 MPa.
For day-to-day sizing, expect about 589 N of dependable working force at 0.5 MPa and roughly 50 kg of vertical lift once a 2:1 margin is applied. The CA pivot back cover takes swinging linkages directly, the magnet comes built in as standard for CMSG / DMSG / EMSG switches, and the 1/4" ports plus M14x1.5 male rod thread speed hookup. Supply 0.15-1.0 MPa (22-145 psi) of 40 um filtered air and it cycles 30-800 mm/s.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 881 N |
| 0.7 MPa | 1374 N | 1234 N |
| Max (@1.0 MPa) | 200 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 MAC50X135SCA Is Used
Tray lidding press
Pressing snap-on lids onto ready-meal trays on a packaging line: 981 N at 0.5 MPa seats lids without crushing, and the 135 mm stroke leaves room to load by hand.
Carton diverter kicker
Knocking cartons off a takeaway conveyor into a reject chute, with about 589 N of usable push and the both-end cushion damping each hit.
Weld jig swing clamp
The CA pivot back cover mounts straight onto a swinging clamp arm on a weld jig, so the cylinder pivots with the linkage - no bracket needed to hold car panels in place.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X135SCA the Right Cylinder?
Look one step down and up when sizing: the 40 mm bore gives 628 N of push at 0.5 MPa and the 63 mm bore 1558 N, so pick the 50 mm when your duty lands between them - about 589 N of real working force is a fair planning number. A plain MAC does not park the rod: with the valve centred or air off, the load will drift, so add a rod lock or pilot check valve where position must hold. The CA pivot cover plus an SDB pivot bracket handles swinging linkages, while FA flange and LB foot suit fixed frames; over 135 mm of stroke, keep the load thrust-aligned or externally guided, as side loads bend the 16 mm rod.
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 MAC50X135SCA FAQ
At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa it pushes 1374 N and pulls 1233 N; the theoretical maximum is 200.1 kgf at 1.0 MPa. Supply 0.15-1.0 MPa (22-145 psi) of 40 um filtered air and cycle it anywhere from 30 to 800 mm/s.
Both ends carry a variable cushion. Back the needle screws fully off before the first cycles, then close them gradually until end-of-stroke knock disappears; this lets you run loads near the 1374 N / 0.7 MPa level without hammering the covers.
