Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 550mm 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 MAC50X550SCA
Air both extends and retracts the rod on this double-acting cylinder, and a variable cushion at each end absorbs the shock of a 50 mm bore delivering 981 N at 0.5 MPa (72 psi). Since 550 mm exceeds the 500 mm standard stroke for this bore, the unit is rolled to order on the same proven barrel design.
Its riveted stainless round barrel and 20 um hard-chrome plated rod resist corrosion in damp or washed-down spots where painted minis fail. A magnet ships inside as standard, so CMSG, DMSG or EMSG switches clip on for position feedback, and at 0.5 MPa you can plan on roughly 589 N of real work rather than the full 981 N rating.

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 MAC50X550SCA Is Used
Bottle-line pusher
Indexes bottle carriers along a rinsing conveyor where the stainless barrel tolerates constant washdown and the 550 mm stroke spans the full lane width.
Drum-lid press
Presses lids onto 200 L drums on a filling line; the variable cushion stops the ram gently on the long downstroke while roughly 589 N of working force seats each lid.
Paint-line swing drive
Drives a swing arm on a paint conveyor; the CA pivot back cover lets the cylinder articulate with the arm without added brackets.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X550SCA the Right Cylinder?
Need less force? A 40 mm bore MAC gives 628 N at 0.5 MPa (72 psi); step up to 63 mm for 1558 N if the load grows. A plain MAC drifts when air is removed, so add a rod lock or pilot check valve wherever the load must stay put. The CA pivot back cover matches an SDB pivot bracket or I/Y rod knuckle, and over the 550 mm stroke keep side load off the 16 mm rod to avoid bending.
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 MAC50X550SCA FAQ
At 0.5 MPa it pushes 981 N and pulls 881 N; at 0.7 MPa push rises to 1374 N; theoretical maximum is 200.1 kgf at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, with a 1/4" port and M14x1.5 rod thread.
Back the needle screws off before start-up, then close them gradually until end-of-stroke impact disappears - the air cushion is variable at both ends, so you can run faster or carry more without hammering the covers.
