About the Airtac B01-SDA Dedicated Cylinder B01-SDA50X40
The AirTAC B01-SDA50X40 is a double-acting, single-rod compact cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA50X40, meaning it is mechanically identical to the base model. It delivers a robust 981.7 N push force at 0.5 MPa, making it highly effective for mid-weight industrial positioning tasks.
Designed with a short riveted body, this unit significantly reduces axial mounting depth compared to conventional round-body actuators, saving valuable machine footprint. The 50 mm bore features a hard-anodized inner wall and uses a fixed NBR bumper at each end to decelerate the stroke. Because this specific SKU lacks the -S magnet option, it cannot directly host magnetic position switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA50X40 Is Used
Injection Mold Ejection
Provides the 981.7 N push force required to eject dense plastic parts from injection molding fixtures, utilizing its 40 mm stroke in a tight press cavity.
Package Diverting
Actuates a diverting arm on a packaging conveyor to reroute heavy cartons, taking advantage of the space-saving riveted body in cramped transfer zones.
Pallet Lift Stops
Raises and lowers mechanical stops on a pallet handling line, where the fixed NBR bumper reliably absorbs the kinetic energy of the 50 kg load at stroke end.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA50X40 the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 yields 628.3 N of push force at 0.5 MPa, whereas stepping up to the SDA63 provides 1558.6 N. The B01-SDA50X40 strikes a strong balance, offering a safe working load of roughly 589 N (about 60% of its 981.7 N capacity) and a vertical lift capability near 50 kg with a 2:1 safety margin.
Remember that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. To maintain vertical position without live pressure, you must integrate an external rod lock or a pilot-operated check valve. For ordering, confirm the 50 mm bore, 40 mm stroke, PT1/4 port, female M10x1.5 rod-end thread, and the absence of a piston magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short-body depth vs. a round-body cylinder
- ✓ Port/thread type (PT)
- ✓ Magnet (S) for sensors?
- ✓ Female (blank) or male (B) rod thread
- ✓ Side load — avoid on a compact rod
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 short piston rod.
- check Very long strokes are unsuitable for the compact body.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac B01-SDA Dedicated Cylinder B01-SDA50X40 FAQ
This double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. Its theoretical maximum push is 200 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
The "B01-" prefix indicates an application-dedicated (customer-specified) line of the standard SDA50X40, with no mechanical changes to the bore, seals, or force. Because this specific SKU lacks the -S magnet option, it cannot host AirTAC reed or electronic switches. You would need the -S variant for position sensing.
