Airtac MAC Stainless Steel Mini Air Cylinder MAC50X290SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X290SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 290mm 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 MAC50X290SCM
With a 50 mm bore driving a 290 mm stroke, the MAC50X290SCM delivers 981 N (about 100 kgf) of push at 0.5 MPa, rising to 1374 N at 0.7 MPa. This is AirTAC's double-acting round-body mini cylinder with a variable air cushion at both ends, so end-of-stroke shock can be tuned out when the stroke runs fast or the load is heavy. The 290 mm stroke sits well inside the 500 mm standard range for this bore, so it is a catalogue item.
A stainless-steel barrel riveted into aluminium covers shrugs off washdown and damp shop air where painted-steel minis corrode - a real advantage in food plants and outdoor cells. The CM round-end back cover takes a pivot pin straight through its rounded tail, and the built-in magnet - standard on every MAC - picks up CMSG, DMSG or EMSG switches with no special-order piston. For sizing, plan on roughly 589 N of usable push at 0.5 MPa; vertically that is about 100 kg of lift at full rating, or 50 kg with a 2:1 margin.

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 MAC50X290SCM Is Used
Casting lift station
Raises aluminium die-cast housings off a gravity conveyor at an engine plant - the 290 mm lift clears a 280 mm tote rim with margin.
Tray index pusher
Slides stacks of food trays across a washdown line; the stainless barrel tolerates frequent hose-down between shifts.
Diverter gate actuator
Swings a process-line diverter gate open and closed, with the air cushion set soft so the gate latches without slamming.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X290SCM the Right Cylinder?
Size down to a MAC40 (628 N push at 0.5 MPa) when the load is light and speed is low, or step up to a MAC63 (1558 N) for heavy clamping - this 50 mm bore holds the middle ground at 981 N. Note the plain MAC does not hold position when air is lost: the piston drifts, so fit a rod lock or pilot check valve for held loads. Over 290 mm of stroke, guide the load externally or use an I or Y rod knuckle to keep side load off the 16 mm rod; FA flange, LB foot or SDB pivot brackets bolt straight on.
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 MAC50X290SCM FAQ
At 0.5 MPa it pushes with 981 N and pulls with 881 N; at 0.7 MPa push rises to 1374 N and pull to 1233 N. The theoretical maximum at 1.0 MPa is about 200 kgf. Working pressure spans 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s, with ports at 1/4" and a 16 mm rod.
Yes - every MAC cylinder carries a built-in magnet as standard, so CMSG, DMSG or EMSG switches clip onto the stainless barrel for end-of-stroke or mid-stroke signals without ordering a special piston.
