Airtac MAC Stainless Steel Mini Air Cylinder MAC50X90SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X90SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 90mm 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 MAC50X90SCA
At its 50 mm bore, this MAC mini cylinder pushes with 981 N and pulls with 881 N at 0.5 MPa, in a double-acting format with a variable air cushion at both ends. The round stainless-steel barrel and hard-chrome plated rod shrug off washdown and damp shop air, a real edge over painted minis in food or outdoor cells. The CA pivot back cover means the cylinder swings on a clevis pin without extra brackets.
Dial the needle screws to tame end-of-stroke shock and run anywhere in the 30-800 mm/s band without hammering the covers. On the load side, budget about 589 N of real work at 0.5 MPa rather than the full 981 N rating; in a vertical line that corresponds to roughly 50 kg lifted with a 2:1 margin. The magnet ships built in, so CMSG or DMSG switches drop straight on.

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 MAC50X90SCA Is Used
Hopper tilt arm
Pivots a 60 kg ingredient hopper on a bottling line; the CA cover swings on a pin and the 981 N push turns the load over smoothly once the cushion is set soft.
Pallet divert gate
Raises a divert gate on a conveyor line every few seconds; the 50 kg vertical lift capability covers a loaded gate with margin to spare.
Light staking press
Presses bushings into aluminium housings on a bench cell; about 589 N of usable force at 0.5 MPa suits light staking over a 90 mm working stroke.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X90SCA the Right Cylinder?
For a 90 mm stroke moving loads in the 50-90 kg class, this bore sits right: the 40 mm version manages only 628 N push at 0.5 MPa, while stepping up to the 63 mm bore buys 1558 N if the job grows. Keep side load off the rod at this length - guide the part externally rather than letting the cylinder take the bending. Working pressure spans 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, and the port is 1/4". AirTAC's FA flange, LB foot and SDB pivot brackets plus I and Y rod knuckles all pair with the CA cover.
One caution: when the valve centres or air is lost, the piston drifts freely - a plain double-acting cushion is not a brake. Fit a rod lock or pilot check valve if the load must stay put.
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 MAC50X90SCA FAQ
At 0.5 MPa the cylinder pushes 981 N and pulls 881 N; at 0.7 MPa push rises to 1374 N with 1233 N on retract. The theoretical maximum is about 200 kgf at 1.0 MPa. Operating range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof, and speed runs 30-800 mm/s.
No - the CA pivot cover is built into the rear end, so a clevis pin mounts it directly. The stainless round barrel and hard-chrome rod cope with damp areas, and the standard built-in magnet accepts CMSG, DMSG or EMSG switches for end-of-stroke signalling.
