Airtac B01-MAC Series Special Purpose Cylinder B01-MAC25X75SU
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC25X75SU 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-MAC25X75SU
Flat U end caps give this 25 mm bore cylinder faces that sit flush against machine plates - no pivot boss in the way. Underneath is the standard AirTAC MAC recipe: a stainless round barrel rolled tight against aluminium covers, a 10 mm hard-chrome rod that laughs at mild corrosion, and double-acting air with an adjustable cushion at each end.
Rated 245.3 N push and 206.1 N pull at 0.5 MPa, it handles about 147 N of sustained work comfortably and lifts roughly 12 kg against gravity with a 2:1 margin. Fluid is 40 um filtered air across 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi). Because the magnet ships fitted, adding a DMSG or EMSG switch is a bolt-on job rather than a special order.

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-MAC25X75SU Is Used
Ejector under a forming die
A 75 mm stroke knocks finished blanks clear of a small press die, with the cushion absorbing the return slap at end of stroke.
Latch on a machine guard
The flat U caps bolt straight to guard framing and drive a latch pin over 75 mm, while the stainless barrel tolerates constant coolant mist.
Sample tray indexer in a lab line
Repeated 75 mm index moves of lightweight trays run anywhere in the 30-800 mm/s band while a CMSG switch on the fitted magnet confirms home position.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC25X75SU the Right Cylinder?
Against neighbours in the range, the 20 mm bore offers 157 N at 0.5 MPa and the 32 mm bore offers 402.2 N, so this bore is the middle ground for a 75 mm stroke. The U back cover wants a fixed attachment, so pair it with an FA flange or LB foot where the frame demands one; air ports are 1/8" and the male rod thread M10x1.25.
Position holding is not built in - vent the cylinder and the rod wanders - so specify a check valve or locking unit for hanging or clamped loads. The cushion needle screws should be opened gradually on first run to find the softest stop.
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-MAC25X75SU FAQ
Push 245.3 N and pull 206.1 N at 0.5 MPa; push 343.4 N and pull 288.5 N at 0.7 MPa; 50 kgf theoretical maximum at 1.0 MPa. Double acting with a variable cushion at both ends, speed 30-800 mm/s, air filtered to 40 um, operating 0.15-1.0 MPa (22-145 psi), proof 1.5 MPa (215 psi), 1/8" port, M10x1.25 rod thread.
U caps are flat and threaded for fixed attachments, while CA and CM provide pivot faces for swinging linkages. On this 25 mm body the U end suits bracket bolting to flat surfaces, and FA, LB or SDB accessories cover anything else. Cushion needles at both ends let you tune the stop from rock hard to feather soft.
