Airtac B06-MAC Battery-Specific Cylinder B06-MAC20X125SU
The AirTAC Airtac B06-MAC Battery-Specific Cylinder B06-MAC20X125SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 125mm stroke, PT/G 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 B06-MAC Battery-Specific Cylinder B06-MAC20X125SU
A 125 mm stroke on AirTAC's 20 mm bore mini cylinder, this MAC20X125SU carries a flat-end U back cover and double-acting power: air extends and retracts the rod, with a variable air cushion at each end to soak up shock. It runs 30-800 mm/s on 0.15-1.0 MPa (22-145 psi) of air filtered to 40 um, and at 0.5 MPa the piston pushes 157 N while pulling 131.9 N.
The body is a stainless barrel rolled onto aluminium covers with a hard-chrome plated rod - a riveted round construction that survives damp and washdown far better than painted minis. For sizing, count on roughly 94 N of usable force at 0.5 MPa, about six tenths of the 157 N rating, rather than the full figure. The magnet comes built in, so CMSG, DMSG or EMSG switches drop straight on.

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 (Ø0mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 0 N | 0 N |
| 0.7 MPa | 0 N | 0 N |
| Max (@1.0 MPa) | 0 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac B06-MAC Battery-Specific Cylinder B06-MAC20X125SU Is Used
Carton pick-and-place
A 157 N push at 0.5 MPa easily lifts and places cosmetic cartons on a packaging line, with the 125 mm stroke clearing a transfer rail.
Terminal press-fit jig
Presses spade terminals into connector housings on a light assembly jig, the variable cushion stopping the ram from slamming at bottom of stroke.
Bottling line divert gate
Swings a diverter flap that routes misaligned bottles off a filling conveyor, using the flat-end U cover for a compact fixed mount.
Is the Airtac B06-MAC Battery-Specific Cylinder B06-MAC20X125SU the Right Cylinder?
Size both ways before committing: the 16 mm bore pushes 100.5 N at 0.5 MPa if the load is light, while the 25 mm bore at 245.3 N covers heavier work - this 20 mm unit at 157 N sits between. Remember that a plain MAC cylinder drifts when air is removed or the valve centres; the cushion is a shock damper, not a brake, so add a rod lock or pilot check valve where a load must be held. The flat-end U back cover bolts straight to a fixed frame, and FA flange, LB foot or SDB pivot mounts can be ordered. At 125 mm of stroke, guide the load externally if any side load or twist is present.
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 B06-MAC Battery-Specific Cylinder B06-MAC20X125SU 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; theoretical maximum is 32.0 kgf at 1.0 MPa. Ports are 1/8", the rod is 8 mm with an M8x1.25 thread, and the 125 mm stroke sits inside the 500 mm standard limit. Proof pressure is 1.5 MPa (215 psi).
Back both cushion needle screws fully out before running, then close them gradually until end-of-stroke shock disappears. The cushion is variable at both ends and works across the 30-800 mm/s speed range; it damps the stop but does not lock the piston in place.
