Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X75SU
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X75SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 75mm 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-MAC20X75SU
Flat-backed and uncluttered: the U back cover presents a plain machined face for direct bolting where a pivot ear would only get in the way. Inside sits the familiar MAC recipe - rolled stainless barrel, hard-chrome plated 8 mm rod, riveted aluminium covers - delivering 157 N of push and 131.9 N of pull at 0.5 MPa across this 75 mm stroke.
Air enters through 1/8" ports, drives the piston both directions, and the variable cushions at each end can be opened up so the load lands gently even near the 800 mm/s ceiling. For sizing, count on around 94 N of continuous working force at 0.5 MPa, a theoretical lift of about 16 kg - or some 8 kg keeping a 2:1 factor. Because the piston magnet is factory standard, CMSG, DMSG and EMSG switches read position from the first shift, no upgrades required.

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-MAC20X75SU Is Used
Chip conveyor slide lock
Pins the chip conveyor slide on a small CNC during cleanout; the flat U tail bolts flush against the conveyor frame.
Gantry cable loom tensioner
Holds light tension on a moving cable loom in a gantry router; retract force of 131.9 N at 0.5 MPa keeps the loom from sagging.
Stamping die blank ejector
Ejects stamped blanks out of a die nest on a small press; the outlet cushion stops the blank skidding off the exit chute.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X75SU the Right Cylinder?
This 75 mm travel is comfortably inside the 500 mm standard limit for a 20 mm barrel, so availability stays short; anything longer is a made-to-order stroke. Compare force classes honestly: MAC16X75 pushes 100.5 N at 0.5 MPa and MAC25X75 manages 245.3 N - if 157 N is a squeeze, step up. Where the load would drop or shift on air loss, add a pilot check valve or rod lock rather than relying on the cushion, which softens impact but never locks. FA, LB or SDB mounting parts pair with the flat U tail as the machine layout demands.
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-MAC20X75SU FAQ
The 20 mm bore pushes 157 N and pulls 131.9 N at 0.5 MPa; at 0.7 MPa expect 219.8 N and 184.7 N respectively, with a theoretical 32.0 kgf maximum at 1.0 MPa. Pressure runs 0.15-1.0 MPa (22-145 psi) and speed 30-800 mm/s.
The barrel cannot flake or rust in misty, washdown or outdoor air, and the 20 um hard-chrome rod resists scoring from airborne dust. Because the covers are rolled and riveted onto the tube rather than clamped by studs, there is nothing to work loose after repeated pressure cycles.
