Airtac B01-MAC Series Special Purpose Cylinder B01-MAC50X125SU
The AirTAC Airtac B01-MAC Series Special Purpose Cylinder B01-MAC50X125SU 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-MAC50X125SU
Rated at 981 N push and 881 N pull on 0.5 MPa air, the MAC50X125SU brings the cushioned 50 mm MAC platform to the U flat-end back cover - a plain squared face that fixes flush against machine walls without brackets. Double acting throughout, with variable air cushions at both ends to temper the stop, it runs 30-800 mm/s across a 0.15-1.0 MPa (22-145 psi) supply, and 0.7 MPa lifts push to 1374 N.
Construction is a riveted stainless barrel with hard-chrome plated rod, the pairing that keeps its surface intact where painted steel minis bubble and flake in washdown corners. Against the 981 N rating, a sensible working figure is about 588 N at 0.5 MPa; vertically that same push would carry a 100 kg mass, halved to a 50 kg lift with margin. The standard-fit magnet means CMSG / DMSG / EMSG switches attach as a bolt-on, no special piston build required.

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-MAC50X125SU Is Used
Fixture hold-down
The U flat end bolts flush to a milling fixture plate, applying a 588 N-class clamp on steel brackets throughout the machining cycle.
Battery change latch
Releases a warehouse forklift battery roller latch, the flat back cover seating directly against the counterweight face with no bracketry.
Bottle ejection paddle
On a bottling line, the cushioned 125 mm stroke kicks rejected bottles off the rail without cracking PET at line speed.
Is the Airtac B01-MAC Series Special Purpose Cylinder B01-MAC50X125SU the Right Cylinder?
Forces bracket the choice neatly: the 40 mm bore manages 628 N push at 0.5 MPa and the 63 mm bore 1558 N, so the 981 N of this 50 mm unit suits jobs in between. When the supply fails or the valve sits mid-travel, the rod will simply drift - pair a pilot check or rod lock with any suspended load. The U flat-end sits flush on a plate; combine with FA flange, LB foot or SDB pivot brackets plus magnet-based CMSG switching for a complete axis. Ports are 1/4 on all 50 mm MAC cylinders.
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-MAC50X125SU FAQ
Push force is 981 N and pull force 881 N at 0.5 MPa; at 0.7 MPa the MAC50X125SU reaches 1374 N push and 1233 N pull, with a 200 kgf theoretical ceiling. Working pressure 0.15-1.0 MPa (22-145 psi), temperature -20 to +70 C, speed 30-800 mm/s.
No - every MAC ships with the piston magnet fitted as standard, so CMSG, DMSG and EMSG reed switches mount directly for position feedback. No special-order piston or retrofit is involved; the switches simply clip to the barrel.
