Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X25SCA
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X25SCA is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 25mm 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-MAC40X25SCA
Ordered with a CA pivot rear cover, this 40 mm bore MAC hangs from a clevis or SDB bracket and swings the 16 mm rod through arcing motions straight out of the box. It is fully double acting - compressed air extends and retracts - with a variable air cushion at each stroke end that you open progressively on first run. Rated push is 628 N at 0.5 MPa and 880 N at 0.7 MPa, inside a 0.15-1.0 MPa (22-145 psi) operating band.
The riveted stainless barrel and hard-chrome-plated rod laugh off wet, dusty air, a genuine edge over painted mini cylinders in food or outdoor plants. For sizing, treat about 377 N - six tenths of the 0.5 MPa push - as your working budget, which corresponds to roughly 32 kg of vertical lift with a 2:1 margin.

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-MAC40X25SCA Is Used
Reject gate on a bottling line
The CA pivot swings a deflector across the bottle lane between sensor detects; 628 N of push holds the gate closed against a full queue of containers.
Carton flap tucker at a case packer
With a DMSG switch confirming retraction, the folded flap is pressed home each cycle; about 377 N of working force seats even glue-stiff board.
Lid swing arm on a dairy filler
The line is washed down every shift - the stainless tube and chrome rod take it, and the pivot mount lets the arm arc clear of the fill heads.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X25SCA the Right Cylinder?
A step down to the 25 mm bore gives 245 N push at 0.5 MPa; a step up to 50 mm reaches 981 N, so 40 mm covers the middle ground for moderate clamps and gates. Because the cushion only dampens end-of-stroke shock and never locks the piston, the rod will drift whenever air is removed - add a pilot check valve or rod lock where a load must stay parked. Speed range is 30-800 mm/s and the magnet comes fitted as standard, so CMSG, DMSG or EMSG switches bolt on without a special-order piston. Fixed frames take FA flange or LB foot mounts; I and Y rod knuckles finish the tooling side.
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-MAC40X25SCA FAQ
At 0.5 MPa the cylinder pushes 628 N and pulls 528 N; at 0.7 MPa push rises to 880 N; the theoretical maximum is 128 kgf at 1.0 MPa. Bore 40 uses a 1/8" port and the male rod thread is M12x1.25.
The CA pivot eye lets the cylinder rock with linkage motion - gate arms, swing levers, toggle clamps - so no fabricated bracket is needed. Combine it with an SDB pivot bracket, or add FA flange and LB foot mounts if the frame is fixed.
