Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X400SCM
The AirTAC B01-MAC Series Special Purpose Cylinder B01-MAC20X400SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 400mm 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-MAC20X400SCM
Position feedback comes free here: every MAC20X400SCM ships with the magnet built into the piston, so CMSG, DMSG or EMSG reed switches bolt straight onto the barrel without a special-order cylinder. The double-acting piston also carries a variable air cushion at each end to soften the 400 mm travel.
The bore 20 stainless body pushes 157 N at 0.5 MPa and 219.8 N at 0.7 MPa, pulling 131.9 N at the lower pressure. Proof pressure is rated at 1.5 MPa (215 psi).

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 |

Where the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X400SCM Is Used
Positioned slide on test rig
Feeds a small fixture into a leak-test station and reports both end positions via bolt-on CMSG switches; the standard magnet makes the feedback wiring trivial.
Reject push-off
Tips off-spec bottles from a filling line lane; 94 N of practical push at 0.5 MPa is ample for empty PET bottles, and twin cushions stop the paddle softly.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X400SCM the Right Cylinder?
If under 100 N at 0.5 MPa suffices, bore 16 (100.5 N) costs less air; beyond 245 N, move to bore 25 (245.3 N) in the same family. Since air loss leaves the piston free to drift, add a rod lock or check valve where a mid-stroke position must persist. The CM round-end cover accepts a pivot pin without adapters, and the standard magnet pairs with CMSG, DMSG or EMSG switches. Long strokes like 400 mm punish side load, so guide the payload separately.
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-MAC20X400SCM FAQ
Push is 157.0 N and pull 131.9 N at 0.5 MPa; at 0.7 MPa push climbs to 219.8 N and pull to 184.7 N, with about 32 kgf theoretical peak at 1.0 MPa. Fluid ports are 1/8 inch, the rod thread is M8x1.25, and the 400 mm stroke is a standard offering up to 500 mm for this bore.
Yes. The variable cushioning at both stroke ends is set by needle screws; start with them backed off, run the cylinder slowly, then open the restriction gradually until end-of-stroke impact disappears. Air must be filtered to 40 um, and the proof pressure is 1.5 MPa (215 psi).
