Airtac MAC Stainless Steel Mini Air Cylinder MAC20X260SU
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X260SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 260mm stroke, 1/8" 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 MAC20X260SU
Flat U rear cover, 260 mm of stroke, and a stainless round barrel that stands up to washdown: the MAC20X260SU is aimed at machines that need a bolt-flat fixing in damp or dusty zones. It is a double-acting mini cylinder, and variable cushions at each end let you soften the last millimetres of travel so faster cycles stay quiet.
The 20 mm bore produces 157 N pushing and 131.9 N pulling at 0.5 MPa, or 219.8 N at 0.7 MPa. Budget about 94 N of usable force and the cylinder lifts close to 8 kg vertically with a 2:1 margin. Every unit ships magnetised, ready for CMSG / DMSG / EMSG position switches with no retrofit.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 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 MAC20X260SU Is Used
Rubber deflash gate
A plate-mounted MAC20X260SU gates deflashed rubber parts from a trim press chute; the flat U cover bolts directly to the chute wall with no adaptor.
Sorter spur carton stop
Stops cartons before a sorter spur merge; 260 mm retract keeps the stop fully clear, and the EMSG switch confirms the down position every cycle.
Spice-mixer blend gate
Opens a blend gate on a spice mixing drum; the riveted stainless body stands up to daily hose-down in a food plant.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X260SU the Right Cylinder?
Compare push at 0.5 MPa: 100.5 N on bore 16, 157 N on this 20 mm bore, 245.3 N on bore 25. A centred valve releases the piston - it drifts - so a rod lock or pilot check valve is needed wherever position must hold. The flat U cover bolts to a machine plate with no adaptor; FA flange, LB foot and SDB pivot brackets suit other layouts. On a 260 mm stroke, guide the load so bending stays out of the 8 mm chrome rod.
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 MAC20X260SU FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa, 219.8 N push and 184.7 N pull; 32.0 kgf theoretical peak at 1.0 MPa. It runs on 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), 30-800 mm/s, with 1/8" ports and an M8x1.25 male rod thread.
Not by itself. A standard MAC drifts whenever the valve centres or air is lost, and the cushion only softens the end of travel - it is not a brake. Fit a rod lock or pilot check valve where the 260 mm stroke must hold position, and use the U flat cover to bolt flat onto a machine plate.
