Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCA
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 280mm 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 B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCA
A round-body stainless mini cylinder built for longer runs, the MAC20X280SCA delivers 157 N of push and 131.9 N of pull at 0.5 MPa over a 280 mm stroke. It is double acting - air extends and retracts the rod - and a variable cushion at each end soaks up shock, so travel can run at up to 800 mm/s without hammering the aluminium covers. The riveted stainless barrel and hard-chrome plated 8 mm rod shrug off washdown and damp shop air that swells painted-steel minis.
Every unit carries a built-in magnet as standard, so a CMSG, DMSG or EMSG switch clips straight on for end-of-stroke sensing with no special-order piston. Keep a working margin and the 157 N push gives you roughly 94 N of real work at 0.5 MPa - enough to shift a 3 kg carton the length of a small conveyor lane.

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 B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCA Is Used
Reject gate pivot
Swings a reject flap on a bottling line: hung from its CA pivot cover, the cylinder flips a light gate through 280 mm with 157 N behind it.
Carton lane diverter
Pushes undersized cartons into a lower lane on a packing conveyor, the adjustable cushion damping every stop at lane end.
Gate feedback loop
A CMSG switch on the standard magnet confirms the gate has fully opened before the filler is allowed to cycle again.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCA the Right Cylinder?
Bore 20 sits between the 16 (100.5 N push at 0.5 MPa) and the 25 (245.3 N), so step up a bore if your load needs more than about 150 N or down if it stays under 100 N. A plain MAC does not hold position when air drops - the rod drifts - so fit a rod lock or pilot check valve if the load must stay put. The CA pivot back cover pairs naturally with an SDB pivot bracket for swing motion; FA flange or LB foot mounts suit fixed frames. At 280 mm, keep side-load off the rod and guide the load externally rather than bending the 8 mm piston 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 B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa those figures rise to 219.8 N push and 184.7 N pull, with a theoretical maximum of 32 kgf at 1.0 MPa. Supply filtered air at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), and the rod travels 30-800 mm/s. It is double acting with a variable air cushion at both ends.
The barrel is a high-precision stainless tube with aluminium covers riveted and rolled onto it, while the carbon-steel rod carries a 20 um hard-chrome plating. Unlike painted-steel or bare-aluminium minis, that combination resists mild corrosion and routine washdown, which matters in food, packaging and outdoor cells.
