Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X80SU
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X80SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 80mm 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-MAC40X80SU
Built on AirTAC's riveted round-body design, the MAC40X80SU uses a flat-end (U) back cover for fixed, bracket-free mounting. The 16 mm hard-chrome rod runs in a stainless barrel that tolerates humidity, splash and outdoor duty where painted minis corrode. Double-acting by design, it sweeps its 80 mm stroke at 30-800 mm/s with a tunable air cushion at both ends.
The 40 mm bore develops 628.3 N pushing at 0.5 MPa and 527.8 N pulling. Treating 60% as usable duty leaves close to 377 N for real work, and in pure lift terms that is about 32 kg carried vertically with a 2:1 safety factor. Back the cushion needles fully off on first run-up, then close them gradually until end-of-stroke knock disappears.

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-MAC40X80SU Is Used
Bakery oven door
Slides the loading door of a rotary bread oven open and closed; the stainless barrel shrugs off flour dust and heat-zone humidity.
Carton reject pusher
Kicks mislabelled cartons sideways off a carton conveyor at 30-800 mm/s, with the cushion damping the return stroke.
Pallet lane stopper
Drops a vertical stop blade in a pallet accumulator, where the 80 mm stroke clears the lane and 527.8 N of retraction force pulls it back quickly.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC40X80SU the Right Cylinder?
Downshift to a 32 mm bore (about 402 N at 0.5 MPa) when force is generous, or step to 50 mm (981 N) when it is tight - this model's 628 N sits between. Because air alone positions the piston, a centred valve leaves the rod free to drift under load; pair it with a pilot-operated check or rod lock where holding matters. The U flat-end back cover mounts flush against a machine face, and the built-in magnet means CMSG / DMSG / EMSG switches need no special-order piston. On the 80 mm stroke, minimise side load on the 16 mm rod or support the moving part externally.
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-MAC40X80SU FAQ
Rated 628.3 N push and 527.8 N pull at 0.5 MPa, rising to 879.6 N push and 738.9 N pull at 0.7 MPa; theoretical peak 128.1 kgf at 1.0 MPa. Ports are 1/8" for this 40 mm bore and the 16 mm rod carries an M12x1.25 male thread. Operating pressure spans 0.15-1.0 MPa (22-145 psi).
The barrel is stainless steel rolled onto aluminium-alloy covers into a riveted, sealed shell, and the rod is hard-chrome plated carbon steel. In damp workshops, splash zones and outdoor frames that combination resists corrosion far better than painted steel, and the riveted body stays tight where screwed joints work loose.
