Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SCA
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø20mm bore and 600mm 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 MAC20X600SCA
Stretching the round-body mini format to 600 mm, the MAC20X600SCA is a made-to-order stroke (the 20 mm bore standard tops out at 500 mm), double acting with a variable air cushion at both ends. At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa, 219.8 N, with a theoretical 32 kgf at 1.0 MPa. A CA pivot back cover lets the cylinder articulate inside the linkage.
For long travels at this scale, plan on about 94 N of genuinely usable force at 0.5 MPa and guide the load externally - the 8 mm rod will bend under side loads across 600 mm. The riveted stainless barrel and hard-chrome rod shrug off moisture and washdown, the standard magnet drives CMSG, DMSG or EMSG switches anywhere along the stroke, and the cushion needles decelerate the slide smoothly at both ends.

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 MAC20X600SCA Is Used
Cross-transfer pusher
Pushes cartons sideways across a conveyor lane; 157 N at 0.5 MPa moves light loads the full 600 mm, with the cushion easing them into the stop.
Tote diverter arm
Swings a diverter between two chute lanes on a pivot mount; the CA eye follows the arc so the long rod stays free of side bending.
Deep-reach oven gate
Slides a cover over a long opening on a drying oven; the stainless barrel and chrome rod cope with warm, humid air up to 70 C.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC20X600SCA the Right Cylinder?
Step down to a 16 mm bore (100.5 N at 0.5 MPa) for light slides, or up to 25 mm (245.3 N) if friction in long guides eats your margin. At 600 mm, side-load control is the real design task: add external guides or pair the CA pivot with an SDB bracket so the rod sees axial force only. Remember that a plain MAC drifts the moment air is removed - for a slide that must stay parked, fit a rod lock or pilot check valve. FA flange and LB foot mounts keep the long body rigid, the 1/8" ports and M8x1.25 rod thread are unchanged, and the magnet is standard for EMSG switching along the barrel.
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 MAC20X600SCA FAQ
The 20 mm bore standard stroke tops out at 500 mm, so 600 mm is produced to order. The cylinder then delivers 157.0 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, and a theoretical 32 kgf at 1.0 MPa, running on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s and -20 to +70 C, double acting with cushions at both ends.
Guide the load on external rails and, where the path pivots, use the CA pivot cover with an SDB bracket so the rod sees axial force only. Back the cushion needle screws off on first run-up, then close them gradually to soften both end stops. The built-in magnet lets an EMSG switch report position anywhere along the barrel, and a rod lock holds the slide if air is ever lost.
