Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X210SCM
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X210SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 210mm 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-MAC20X210SCM
Jigs, clamps and small gantries that need long reach get 210 mm of it from this 20 mm MAC, a double-acting mini cylinder with variable cushions at each end. Expect 157 N push and 131.9 N pull at 0.5 MPa, rising to 219.8 N push at 0.7 MPa, through 1/8" ports. Back the cushion needles off on first run-up, then close them gradually to tune the deceleration.
Built the AirTAC mini way: a rolled, riveted stainless barrel with aluminium covers and a hard-chrome carbon-steel rod that tolerates splashes and humidity better than painted bodies. Full-pressure theoretical force peaks near 32 kgf, but sizing around 94 N at 0.5 MPa keeps the mechanism healthy for years. The CM round-end back cover bolts flat where a pivot would wander, and the standard magnet accepts CMSG / DMSG / EMSG switches 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-MAC20X210SCM Is Used
Ejector on a small stamping press
The CM round-end cover bolts the body flat to the press frame; 219.8 N at 0.7 MPa ejects light blanks over the full 210 mm stroke.
Sample tray indexer in a lab line
Mild detergents in splash zones do not pit the stainless barrel, and DMSG switches confirm each tray park along the 210 mm travel.
Case diverter at a sorter exit
Swung from an SDB pivot bracket, the cylinder flicks lightweight cartons off the lane, with cushions tuned so the arm stops without clatter.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X210SCM the Right Cylinder?
Compare before you commit: 16 mm bore tops out at 100.5 N push at 0.5 MPa and 25 mm bore reaches 245.3 N, so this 20 mm sits squarely between them. At 210 mm the 8 mm rod is long for its diameter - keep the load guided and side-force free, or choose the 25 mm MAC for its 10 mm rod. The CM round-end cover suits bolt-on fixing; SDB pivot, FA flange or LB foot brackets bolt on when the frame needs them. If the load must stay put on air loss, fit a rod lock or pilot check valve, because the cylinder itself will not hold position.
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-MAC20X210SCM FAQ
At 0.5 MPa: 157 N extend, 131.9 N retract. At 0.7 MPa: 219.8 N extend, 184.7 N retract. The ceiling is 32 kgf of theoretical force at 1.0 MPa, within an operating pressure of 0.15-1.0 MPa (22-145 psi).
Yes - variable air cushions sit at both ends. Open the needles fully at commissioning, then close them stepwise until end-of-stroke knock stops; rated speed spans 30-800 mm/s.
