Airtac B01-MAC Series Special Purpose Cylinder B01-MAC25X280SCM
The AirTAC B01-MAC Series Special Purpose Cylinder B01-MAC25X280SCM 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-MAC25X280SCM
A 280 mm stroke with a clevis-friendly round rear end makes the MAC25X280SCM a natural for swinging linkages: the CM cover takes a clevis or pin directly, so the cylinder can follow an arc without side-loading the 10 mm hard-chrome rod. Double acting throughout, it pushes 245.3 N at 0.5 MPa on a 25 mm bore, and the cushions at both ends are adjustable with plain needle screws.
The stainless barrel and rolled-joint construction tolerate humid, dusty and lightly washed environments better than painted steel minis, and the standard piston magnet works with CMSG / DMSG / EMSG switches from day one.

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-MAC25X280SCM Is Used
Chute flap on a grain auger
A clevis-pivoted flap diverts grain between two augers; the CM round end tracks the arc cleanly over the full 280 mm throw.
Carton-sealer glue head
The rod advances a glue head across a 280 mm carton seam; needle-screw cushions stop the head precisely at the flap edges.
Scraper arm on a screen filter
A pivoting scraper sweeps debris off a wedge-wire screen; stainless construction survives constant water contact outdoors.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC25X280SCM the Right Cylinder?
Neighbouring bores frame the choice: 20 mm yields 157 N at 0.5 MPa and 32 mm yields 402.2 N; pick either if 245.3 N overshoots or undershoots your load. This is a free-floating double-acting unit - centre the valve and the rod coasts wherever the load takes it, so a pilot check valve or rod lock is essential for suspended work.
The round CM end suits clevis mounts, while FA flange and LB foot brackets handle fixed frames; over 280 mm of stroke, guide the payload externally so side force never reaches the rod. 1/8" ports feed both chambers.
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-MAC25X280SCM FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N at 0.7 MPa; theoretical maximum 50 kgf at 1.0 MPa. Size actuators around 147 N of continuous work.
It cannot - air loss or a centred valve lets the rod drift, and the air cushion is not a brake. Fit a rod lock cylinder or an in-line pilot check valve wherever the load must stay put.
