Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCM
The AirTAC B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 280mm 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-MAC20X280SCM
With 157 N of push at 0.5 MPa across a 280 mm stroke, the MAC20X280SCM covers the light-duty band of AirTAC's MAC family - and the CM round-end back cover gives you a clevis-style pivot point without extra brackets. This is a double-acting cylinder: air drives the rod out and pulls it back, and needle screws at both ends tune the air cushion so fast cycles land softly. Stainless round tube, hard-chrome rod, rolled aluminium covers: it keeps sealing where painted-steel minis start to flake in humid or food-wash corners.
Position feedback needs no special-order piston, because the magnet ships inside as standard - just clip a CMSG, DMSG or EMSG switch to the barrel.

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-MAC20X280SCM Is Used
Dosing slide on a filler
Slides a small dosing head across a filling station, giving 280 mm of travel with 157 N of push behind it at 0.5 MPa.
Tray indexer
Advances formed trays one station at a time on a tray erector, the twin cushions absorbing the index stop at up to 800 mm/s.
Glue-head traverse
Carries a glue nozzle across a box blank on a carton lines, mounted on the CM round-end cover in a simple link.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC20X280SCM the Right Cylinder?
If 157 N at 0.5 MPa is more than you need, the bore 16 version gives 100.5 N; if the load creeps past 200 N, the bore 25 with 245.3 N push is the right step. The rod is not locked in place - centre the valve or lose air and it drifts - so add a pilot check valve or rod lock wherever a mid-stroke load must stay parked. Choose this CM cover when the cylinder pivots in a yoke or link; otherwise U flat-end or CA pivot covers, plus FA / LB / SDB brackets, cover fixed frames. Over a 280 mm stroke, support the load externally so the 8 mm rod sees little side force.
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-MAC20X280SCM FAQ
At 0.5 MPa: 157 N push and 131.9 N pull. At 0.7 MPa: 219.8 N push and 184.7 N pull. The theoretical peak is 32 kgf at 1.0 MPa. Working range is 0.15-1.0 MPa (22-145 psi) with 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, speed 30-800 mm/s, temperature -20 to +70 C. Double acting, variable air cushion both ends.
Back both cushion needle screws fully off before start-up, run the cylinder slowly, then close them gradually until end-of-stroke impact disappears. The cushion is variable, not fixed, so you can re-tune it whenever speed or load changes - useful at the upper end of the 30-800 mm/s band.
