Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X25SU
The AirTAC B01-MAC Series Special Purpose Cylinder B01-MAC40X25SU 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-MAC40X25SU
Flat-ended and bolt-through friendly, the U rear cover on this 40 mm bore MAC seats directly against machine plates. Double-acting air both extends and retracts the rod across 25 mm, and the variable cushion at each end - opened fully for first run, then dialled in - takes the sting out of 628 N push force at 0.5 MPa.
Grease stored in the heterogeneous piston seal keeps friction low along the hard-chrome 16 mm rod, so the cylinder tolerates dusty farm implements and packaging frames between services.

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-MAC40X25SU Is Used
Seed meter gate on a planter
Field dust and fertilizer residue meet a sealed stainless barrel; 628 N of push holds the gate shut against seed pressure through a full hopper.
Tray pusher on a bakery line
The flat U rear mounts straight to the frame rail, and the cushions stop the tray from bouncing at the end of the 25 mm push.
Ejector pin on a small stamping die
With a Y knuckle picking up the punch, the cylinder ejects blanks using about 377 N of working force at 0.5 MPa.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X25SU the Right Cylinder?
Bore 20 tops out at 157 N push at 0.5 MPa and bore 63 at 1558 N, which frames 40 mm as the mid-duty pick for gates, clamps and small lifts. Do not use the cylinder as a position holder: with the valve centred or air lost, an unbalanced load walks the rod - a pilot check valve or rod lock is the fix. The U end bolts flat to plates, or choose FA flange, LB foot and SDB pivot brackets plus I / Y knuckles for the rod side. Pressure window is 0.15-1.0 MPa (22-145 psi), speed runs 30-800 mm/s, and the magnet is standard, so CMSG, DMSG and EMSG switches fit with no special piston.
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-MAC40X25SU FAQ
Push 628 N and pull 528 N at 0.5 MPa, push 880 N at 0.7 MPa, and 128 kgf theoretical maximum at 1.0 MPa. Air ports are 1/8", the rod is 16 mm hard-chrome steel with M12x1.25 thread, and the 25 mm stroke sits well inside the 500 mm maximum standard stroke for this bore.
Yes - every MAC ships with the magnet built in as standard, so CMSG, DMSG or EMSG reed or electronic switches clamp onto the barrel whenever end-of-stroke confirmation is needed. No special-order piston is required.
