Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCAH
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCAH is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 80mm 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 MAC50X80SCAH
Built for jobs where the actuator hangs on a pin, this 50 mm bore MAC variant pushes 981 N at 0.5 MPa over an 80 mm stroke. Double-acting air power extends and retracts the rod, and the adjustable air cushion at both ends can be tuned so heavy or fast-moving loads settle instead of slamming the covers. Operating span is 0.15-1.0 MPa (22-145 psi), with proof testing at 1.5 MPa (215 psi).
The riveted stainless barrel and 20 um hard-chrome rod stand up to damp, dusty and lightly corrosive surroundings where painted mini cylinders fail early. Its 981 N push equals about 100 kgf, so with a 2:1 margin it will lift roughly 50 kg vertically - a handy yardstick when matching part weights. The CA rear pivot mounts directly on linkage pins, and the magnet fitted as standard drives CMSG / DMSG / EMSG position switches. Note the trailing H in the order code: confirm that thread option from the datasheet before ordering.

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 MAC50X80SCAH Is Used
Seed-drill marker arm
Folding a field marker on a seeding rig: mud, rain and fertiliser splash make the hard-chrome rod and stainless tube the durable pick, while the CA pivot follows the arm's natural arc.
Coffee-roaster discharge chute
Tipping the bean chute of a commercial roaster between batch and dump positions; the piston will drift if air is lost mid-batch, so the panel adds a pilot check valve to pin the chute.
Filling-turret lock pin
Plunging a lock pin into the index plate of a rotary filling turret; the 80 mm stroke clears the pin fully, and the standard magnet fires a CMSG switch at full retract.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X80SCAH the Right Cylinder?
If 981 N is more than the job needs, the 32 mm bore MAC32X80 does 402 N at 0.5 MPa; if it falls short, the 63 mm MAC63X80 delivers 1558 N. The piston floats freely whenever the valve is centred or supply fails, so anything that must stay put demands a pilot check valve or rod lock in the circuit. Mounting runs through the CA pivot pin, with FA flange, LB foot and SDB pivot brackets for rigid frames. Ports measure 1/4" on all 50 mm bores and the rod thread is M14x1.5; the trailing H in this order code is a thread option - confirm it from the datasheet before ordering.
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 MAC50X80SCAH FAQ
Figures for the 50 mm bore: 981 N push and 881 N pull at 0.5 MPa; 1374 N push and 1233 N pull at 0.7 MPa; up to 200 kgf theoretical thrust at 1.0 MPa.
Back both cushion needle screws fully off before start-up, cycle the rod slowly, then close each screw gradually until end-of-stroke impact disappears. The cushion is variable, not fixed, so it can be retuned whenever speed or load changes within the 30-800 mm/s range.
