Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X150SCA
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X150SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 150mm 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-MAC20X150SCA
The MAC20X150SCA is AirTAC's double-acting mini cylinder in a 20 mm bore with a 150 mm stroke, finished with a CA pivot back cover so the body can rock on a pin with the mechanism it drives. Fed through 1/8" ports at 0.15-1.0 MPa (22-145 psi), it pushes 157 N and pulls 131.9 N at 0.5 MPa, rising to 219.8 N at 0.7 MPa. A variable air cushion sits at each end, so end-of-stroke shock is tuned out with the needle screws instead of hammering the covers.
Inside is a stainless round barrel rolled onto aluminium covers with a hard-chrome plated 8 mm rod, a body that tolerates washdown and damp shops far better than painted minis. Budget about 94 N of the 157 N push for real work at 0.5 MPa, which lifts roughly 8 kg vertically with a 2:1 margin. The magnet is built in as standard, so CMSG, DMSG or EMSG switches clip straight on, and speeds run from 30 to 800 mm/s.

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-MAC20X150SCA Is Used
Chute deflector arm
Swings a sorting-chute deflector on a small parcel sorter; the CA pivot body pins straight to the gate link and the cushion tames the swing at each end.
Bottle reject gate
Kicks underfilled bottles off a bottling-line rail with about 94 N of usable force, enough for lightweight PET containers moving at moderate line speed.
Sample tray indexer
Advances a 96-well sample tray one station at a time on a lab autosampler, with the standard magnet signalling home position via a CMSG switch.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X150SCA the Right Cylinder?
At 157 N of push, this 20 mm bore sits between the 16 mm MAC (100.5 N at 0.5 MPa) and the 25 mm MAC (245.3 N) - step down for light indexing, up for firmer clamping. Like every double-acting MAC it drifts when air is lost or the valve centres, so fit a pilot check valve or rod lock if the 150 mm position must hold. The CA pivot cover takes a clevis-style pin directly; FA flange, LB foot or SDB pivot brackets bolt on if the frame needs them, and the built-in magnet needs no special-order piston. Over the 150 mm stroke keep side load off the 8 mm rod with a guide, since an unsupported long rod will bend under offset force.
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-MAC20X150SCA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa the figures are 219.8 N push and 184.7 N pull. The theoretical maximum is 32.0 kgf at 1.0 MPa on the 20 mm bore. Air supply is 0.15-1.0 MPa (22-145 psi) filtered to 40 um.
The magnet is fitted as standard on every MAC, so AirTAC CMSG, DMSG and EMSG reed or electronic switches mount on the barrel without a special piston. Check switch seating after mounting, then set your PLC inputs against the two ends of the 150 mm stroke.
