Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X75SU
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X75SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 75mm 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-MAC40X75SU
A 75 mm stroke on a 40 mm bore makes the MAC40X75SU a mid-range pusher: 628 N out and 528 N back at 0.5 MPa, climbing to 880 N at 0.7 MPa. The U flat-end back cover presents a machined face that bolts flush to a plate or machine wall, no pivot needed. AirTAC forms the body by rolling the aluminium covers and a stainless block onto a precision stainless tube, a riveted pack that stays sealed over millions of cycles.
Mounted vertically, the rod column supports about 64 kg at 0.5 MPa, so lifting around 32 kg keeps a 2:1 margin - a handy yardstick for matching hopper or gate weights. The two-way piston seal also stores its own grease, stretching relubrication intervals, and 20 um of hard chrome on the 16 mm rod resists scoring in gritty air. The magnet is built in as standard, so CMSG or DMSG switches fit without a special-order piston.

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-MAC40X75SU Is Used
Hopper gate on a bottling filler
Lifts a slide gate under a 30 kg ingredient hopper - about 32 kg of vertical lift with a 2:1 margin at 0.5 MPa, the U cover bolted flat to the machine frame.
Flap hold-downs on a case erector
Pushes carton flaps square while the glue cures; the 528 N return retracts cleanly at cycle speeds up to 800 mm/s.
Bush press-fit on an assembly bench
Presses sintered bushings into pump housings; roughly 377 N of practical work force at 0.5 MPa suits small interference fits without bruising the part.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X75SU the Right Cylinder?
Force ladder at 0.5 MPa: 402 N from a 32 mm bore, 628 N from this 40 mm bore, 981 N from a 50 mm bore - step up a size whenever your load sits close to the rating. Ports are 1/8" and the male rod thread is M12x1.25. When the valve centres or air is lost, the piston is free to move, so a pilot check valve or rod lock is the fix where a load must stay put. FA flange, LB foot or SDB pivot brackets bolt straight on, and the standard magnet suits CMSG, DMSG and EMSG switches for stroke-end signals.
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-MAC40X75SU FAQ
Push is 628 N and pull 528 N at 0.5 MPa; raise the supply to 0.7 MPa for 880 N push and 739 N pull. Theoretical peak output is 128 kgf at 1.0 MPa. It is double acting on filtered air at 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), running 30-800 mm/s.
It gives a flat machined face for direct bolting to a wall or bracket - no pivot, no extra hardware. If your mechanism swings instead, choose the CA pivot or CM round-end cover or add an SDB pivot bracket. LB foot and FA flange mounts are also on offer, and every cylinder arrives with the magnet fitted for CMSG, DMSG and EMSG sensors.
