Airtac B01-MAC Series Special Purpose Cylinder B01-MAC25X125SU
The AirTAC B01-MAC Series Special Purpose Cylinder B01-MAC25X125SU is a genuine double acting + cushion standard round-body mini air cylinder with a Ø0mm bore and 125mm 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-MAC25X125SU
Flat rear face, 125 mm of travel, 245.3 N of push at 0.5 MPa - that is the MAC25X125SU in one line. The U back cover butts against plates and fixtures without adaptors, and pull force at the same pressure is 206.1 N. Raise supply to 0.7 MPa for 343.4 N push / 288.5 N pull, with 50 kgf theoretically on tap at 1.0 MPa.
Both ends carry a variable air cushion, so fast strokes on this 125 mm travel can land without shock even at 800 mm/s. The riveted round body combines a stainless tube, aluminium covers and a hard-chrome plated rod - a build that copes with splash, humidity and periodic cleaning where painted minis corrode. A piston magnet is included as standard for CMSG, DMSG or EMSG switches, and the air connection is 1/8 inch within a 0.15-1.0 MPa (22-145 psi) operating band.

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-MAC25X125SU Is Used
Stamping press part ejection
Ejects finished blanks from a small stamping die at a jobbing shop, where the flat rear end bolts square against the die plate.
Film slitter web guide
Trims the lateral position of a moving film web on a slitting machine, with the 125 mm stroke matching typical guide travel.
QC bench specimen clamp
Clamps samples into a laboratory test rig, where the cushion prevents an abrupt grab on delicate parts at end of stroke.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC25X125SU the Right Cylinder?
A bore 20 alternative returns 157.0 N push at 0.5 MPa while a bore 32 reaches 402.2 N, so 245.3 N from this 25 mm bore covers the middle ground. No air means no holding: once supply drops or the valve centres, the rod drifts under load, so specify a rod lock or check valve where position must persist. The flat U end suits rigid rear mounting; switch to CA or CM for pivot duty. Guide any off-axis load externally - with 125 mm of stroke, small side forces multiply into real rod bending at full extension.
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-MAC25X125SU FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N; at 0.7 MPa the figures are 343.4 N push and 288.5 N pull; theoretical maximum output is 50 kgf at 1.0 MPa. The cylinder is double acting with variable air cushioning at both ends, runs on 0.15-1.0 MPa (22-145 psi) at 30-800 mm/s, and ports at 1/8 inch.
The round barrel is stainless steel riveted to aluminium covers, and the rod is carbon steel hard-chrome plated to about 20 um. That combination resists corrosion from splash, humidity and periodic washdown, which is why it suits food-adjacent, outdoor and damp workshop duties better than painted mini cylinders.
