Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCASDB
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCASDB is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 450mm 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 MAC50X450SCASDB
Pivot hardware already fitted: the SCASDB build adds an SDB pivot mounting bracket to the CA back cover, so the 450 mm cylinder swings inside a fixed frame with no extra plates to design. Air acts on both sides of the piston with a variable cushion at each end, delivering about 981 N of push at 0.5 MPa through a 1/4 inch port.
For vertical work, the 981 N rating equals roughly 100 kg of lift at the rod - halve it and you still raise about 50 kg with margin, enough for hoppers or tooling plates. Long strokes like this see side loads, so keep the rod aligned or add a guide, since a 16 mm rod will deflect under off-axis force. The stainless barrel shrugs off corrosion in outdoor and washdown cells, and the magnet fitted as standard pairs with CMSG / DMSG / EMSG switches straight out of the box.

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 MAC50X450SCASDB Is Used
Hopper slide gate on a batching plant
The SDB bracket anchors the swing mount while 981 N at 0.5 MPa drags the slide gate across a 450 mm aggregate outlet.
Tooling plate lift in a stamping cell
Count on roughly 50 kg of vertical lift with a 2:1 margin - enough for die shoes and fixtures that must rise and park reliably.
Loading-dock gate actuator
Out in the weather, the stainless riveted body resists rust while the 450 mm stroke swings the dock gate open and shut.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X450SCASDB the Right Cylinder?
Between the MAC40X (628 N at 0.5 MPa) and the MAC63X (1558 N), this 50 mm bore occupies the mid-power slot. If the bracket is not needed, the plain CA (SCA) or round-end CM (SCM) back covers mount more cheaply; FA flange and LB foot parts cover rigid frames. Pressure window is 0.15-1.0 MPa (22-145 psi) and speed spans 30-800 mm/s. The cylinder will not hold a load if air is lost - it drifts wherever the forces take it - so a rod lock or pilot check valve is the fix for suspended loads. Port thread is PT as standard, with G and NPT (T) on request.
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 MAC50X450SCASDB FAQ
Extension force is 981 N and retraction force 881 N at 0.5 MPa; at 0.7 MPa expect 1374 N out and 1233 N back. Theoretical peak is 200 kgf at 1.0 MPa. Port size is 1/4 inch, rod diameter 16 mm with M14x1.5 thread, and the 450 mm stroke is standard up to 500 mm.
The SDB pivot bracket is fitted as part of the build, so a swinging mount in a fixed frame needs no second bracket plate or custom sheet-metal work. You still get the CA pivot back cover, the 1/4 inch port, the adjustable air cushion and the standard magnet, all in one orderable code.
