Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X270SCM
The AirTAC B01-MAC Series Special Purpose Cylinder B01-MAC20X270SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 270mm 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-MAC20X270SCM
At 0.5 MPa the MAC20X270SCM develops 157 N forward and 131.9 N back over a 270 mm stroke - a double-acting round-body mini built for long, light movements. Variable air cushions at both ends are tuned with needle screws, so faster or heavier moves stop soft instead of banging the aluminium covers. Working pressure spans 0.15-1.0 MPa (22-145 psi) and rod speed runs 30-800 mm/s.
Construction is a riveted stainless-steel barrel with a 20 um hard-chrome carbon-steel rod, so damp workshops, rinse zones and outdoor frames do not chew it up the way they do painted minis. The magnet is standard, meaning CMSG / DMSG / EMSG switches mount without a special-order piston.

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-MAC20X270SCM Is Used
Specimen pusher in a materials lab
Moves loaded sample trays the full 270 mm into a furnace or test frame; 157 N at 0.5 MPa is ample for the carrier, and the stainless barrel wipes down between batches.
Palletizer layer aligner
Squares up stray cartons on the layer-forming table before pressing; the CM round-end cover picks up the pivot pin on the pusher arm without adapters.
Damper blade actuator on a dust extractor
Opens and closes a balancing damper through 270 mm of blade travel; needle-adjusted cushions stop the blade slamming metal-to-metal at either end of its arc.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X270SCM the Right Cylinder?
The 16 mm bore tops out at 100.5 N push at 0.5 MPa, so upsize to this 20 mm model when that falls short; the 25 mm bore offers 245.3 N if you later need more muscle. Do not count on the cylinder to hold position - with the valve centred the piston drifts, so spec a rod lock or pilot check valve for held loads. Mounts stay flexible: FA flange, LB foot or SDB pivot brackets, I or Y knuckles on the rod, with the CM round-end back cover making clean pivot arrangements easy.
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-MAC20X270SCM FAQ
Rated figures for this 20 mm bore: 157 N extend and 131.9 N retract at 0.5 MPa; 219.8 N extend and 184.7 N retract at 0.7 MPa; ceiling 32 kgf at 1.0 MPa theoretical. Feeding it 0.15-1.0 MPa (22-145 psi) of 40 um filtered air keeps the 30-800 mm/s speed range honest.
The MAC20X270SCM pairs a rolled stainless-steel barrel and a 20 um hard-chrome plated rod with aluminium covers, so splash, humidity and routine rinsing cause far less trouble than on painted-steel mini cylinders. It is a riveted round-body design with no external fasteners to loosen in wet service.
