Airtac MAC Stainless Steel Mini Air Cylinder MAC50X500SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC50X500SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø50mm bore and 500mm 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 MAC50X500SU
A 500 mm stroke on a 50 mm bore turns the MAC50X500SU into a long-reach pusher: 981 N of push and 881 N of pull at 0.5 MPa, rising to 1374 N of push at 0.7 MPa. Air pressure spans 0.15-1.0 MPa (22-145 psi) and rod speed runs 30-800 mm/s, so even this long travel can be cycled quickly.
Construction is a stainless round barrel with the aluminium covers rolled on, gripping a 16 mm hard-chrome plated rod that shrugs off washdown and damp plant air. A variable air cushion at both ends dials out end-of-stroke shock, so heavier layers can be moved at speed without hammering the covers. The magnet is built in as standard for CMSG / DMSG / EMSG switches. In practice, plan on about 589 N of usable force at 0.5 MPa - roughly 60% of the rating - which corresponds to lifting about 50 kg vertically at 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 MAC50X500SU Is Used
Palletizer layer pusher
Squares stacked carton layers on a palletizer infeed with 500 mm of travel; 981 N at 0.5 MPa shifts a full layer while the dual cushions settle it against the end stop.
Furnace door slide
Drives a small heat-treat oven door sideways; the stainless barrel and chrome rod cope with hot, dusty air, and roughly 50 kg of vertical component can be handled at a 2:1 margin.
Deep-draw stripper
Strips formed shells off the punch in a press shop; plan the tooling around 589 N of usable force at 0.5 MPa rather than the full 981 N rating.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC50X500SU the Right Cylinder?
Compare both directions before you commit: the 40 mm bore delivers 628 N at 0.5 MPa and the 63 mm bore 1558 N, so this 50 mm size at 981 N sits between them. When the supply drops or the valve centres, both chambers vent and the rod free-drifts with no holding force, so a pilot check valve or rod lock is the fix for a parked load. At 500 mm of stroke, keep side loads off the 16 mm rod by guiding the part externally; FA flange, LB foot or SDB pivot brackets bolt straight on, and the standard magnet pairs with CMSG / DMSG / EMSG switches along the full travel.
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 MAC50X500SU FAQ
The 50 mm bore, double-acting MAC pushes 981 N and pulls 881 N at 0.5 MPa; at 0.7 MPa push rises to 1374 N and pull to 1233 N, with a theoretical maximum of 200 kgf at 1.0 MPa. Ports are 1/4", the 16 mm rod carries an M14x1.5 male thread, and 500 mm is the maximum standard stroke for this bore.
The round barrel is stainless steel rolled tight against the covers, while the 16 mm rod is hard-chrome plated carbon steel - a pair that tolerates washdown, condensation and mild chemicals far better than painted minis. Run it on 40 um filtered air anywhere in the 0.15-1.0 MPa (22-145 psi) band, and open the cushion needles gradually on first start-up.
