Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X400SCA
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X400SCA 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-MAC20X400SCA
A 400 mm stroke on a 20 mm bore is a long reach for a mini cylinder, and the MAC20X400SCA handles it with double-acting power and adjustable air cushioning at both ends that you tune with the needle screws. The riveted stainless barrel and hard-chrome carbon rod shrug off splash and outdoor damp.
Force at 0.5 MPa is 157 N pushing and 131.9 N pulling; at 0.7 MPa push rises to 219.8 N. Derate to about 94 N of usable push for sizing, which equates to lifting roughly 8 kg vertically on a 2:1 margin. Speed range is 30-800 mm/s within a 0.15-1.0 MPa (22-145 psi) supply.

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-MAC20X400SCA Is Used
Swing-lock latch
Rotates a machine guard latch through a linkage; the CA pivot back cover mounts the cylinder directly on the swinging arm, and dual cushions stop the latch without clatter.
Light-duty lift gate
Raises a hinged inspection cover weighing about 8 kg; that sits inside the 2:1 vertical margin of the 157 N push at 0.5 MPa over a 400 mm opening stroke.
Stopper gate on assembly line
Drops a stop blade to hold small parts at a manual workstation; the long stroke lets the blade park fully clear of the part path between cycles.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X400SCA the Right Cylinder?
Compare against bore 16 at 100.5 N push (0.5 MPa) for lighter tasks or bore 25 at 245.3 N for heavier ones before fixing on 20 mm. Remember the piston is not held by anything once supply drops: a centred valve lets the load creep, so spec a rod lock or pilot check for held positions. The CA pivot back cover suits swinging linkages, with FA flange, LB foot and SDB pivot brackets available. On this 400 mm stroke, align the load axis carefully and support long rods against bending.
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-MAC20X400SCA FAQ
Expect 157.0 N push and 131.9 N pull at 0.5 MPa, rising to 219.8 N push and 184.7 N pull at 0.7 MPa; theoretical maximum is about 32 kgf at 1.0 MPa. The bore 20 cylinder breathes through 1/8 inch ports, uses an M8x1.25 rod thread, and the 400 mm stroke is within its 500 mm standard ceiling.
The magnet is built in as standard equipment on every MA-series piston, so CMSG, DMSG and EMSG switches clip onto the barrel for end-of-stroke or mid-stroke signalling with no special order. Supply air at 0.15-1.0 MPa (22-145 psi) and keep speed within 30-800 mm/s.
