Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X300SCM
The AirTAC B01-MAC Series Special Purpose Cylinder B01-MAC20X300SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 300mm 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-MAC20X300SCM
Round-end CM covers give the MAC20X300SCM a smooth, snag-free tail for tight frames, while the 20 mm stainless barrel drives a 300 mm stroke with 157 N of push and 131.9 N of pull at 0.5 MPa. Double acting throughout, with a variable air cushion at both ends that you tune via the needle screws to soften landings anywhere in the 30-800 mm/s band.
Built as a rolled, riveted body with a hard-chrome plated rod, it stands up to humidity and light washdown where painted minis rust. The magnet comes standard, so CMSG, DMSG or EMSG switches mount without a custom piston. Proof pressure is 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 |
| 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-MAC20X300SCM Is Used
Sliding shield on a CNC coolant enclosure
Slides a 300 mm polycarbonate guard across the spindle area; the CM round end tucks inside the machine shroud and the cushion quiets each close.
Carton stop on a gravity roller lane
Pops up to halt boxes at a pick face; 157 N push at 0.5 MPa holds the stream and the stainless barrel survives unheated dock humidity.
Trim gate on a small water tank
The corrosion-proof rod and barrel work outdoors, opening a 300 mm drain gate; the built-in magnet feeds a CMSG switch for open/closed status.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X300SCM the Right Cylinder?
The 16 mm bore manages 100.5 N at 0.5 MPa and the 25 mm bore reaches 245.3 N, so bracket this model when the load sits between those figures. Its CM round end suits clevis-style or simple fixed linkages; FA flange and LB foot brackets bolt on if a base is needed. Air on both sides means nothing stops the rod when supply drops - plan a pilot check valve or rod lock for held loads. Confirm side-load limits from the datasheet before running at full speed.
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-MAC20X300SCM FAQ
It pushes 157 N and pulls 131.9 N at 0.5 MPa; at 0.7 MPa the figures are 219.8 N and 184.7 N; theoretical peak is 32 kgf at 1.0 MPa. Ports are 1/8" and the rod thread is M8x1.25 on this 20 mm bore with an 8 mm rod.
Back both needle screws fully off, stroke the cylinder slowly, then close each needle gradually until the end-of-stroke bump disappears. The cushion is variable air, not a brake - it cannot hold a load if air pressure is lost.
