About the Airtac B01-SDA Dedicated Cylinder B01-SDA50X50SB
The AirTAC B01-SDA50X50SB is a double-acting, single-rod compact cylinder engineered for tight axial spaces. The leading B01- prefix designates this as an application-dedicated, customer-specified variant of the base SDA50X50SB, meaning it is mechanically identical to the standard model but grouped for specific industrial use cases. Delivering 981.7 N of push force at 0.5 MPa, it features a 50 mm stroke and a 20 mm piston rod.
This model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It is configured with a male-thread piston rod (-B) measuring M18x1.5, providing a robust external load coupling. The short riveted body significantly reduces mounting depth compared to round-body cylinders, and end-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA50X50SB Is Used
Carton Erector Flap Folding
Provides the 981.7 N push force required to cleanly fold heavy cardboard flaps on high-speed packaging lines, with the male M18x1.5 rod securely driving the folding arm.
Pallet Diverting Gate
Actuates heavy redirect gates on conveyor systems; the short riveted body saves valuable axial depth within tight transfer zones while handling the 50 kg dynamic load.
Injection Mold Part Extraction
Ejects molded plastic parts from press cavities, utilizing the built-in magnet with an electronic switch to confirm full retraction before the mold closes.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA50X50SB the Right Cylinder?
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 bore yields 628.3 N of push at 0.5 MPa, whereas stepping up to the SDA63 bore provides 1558.6 N. This 50 mm bore offers a safe working load of roughly 589 N (about 60% of its 981.7 N capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin. To order, confirm the 50 mm bore, 50 mm stroke, PT1/4 port, built-in magnet, and male M18x1.5 rod thread.
Keep in mind that a standard compact cylinder does not hold its position if air pressure is lost or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the load near the stroke end without acting as a lock. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
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-SDA50X50SB FAQ
This double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa. It operates at speeds between 30-500 mm/s, with a maximum operating pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
The B01- prefix simply marks this as an application-dedicated, customer-specified variant of the standard SDA50X50SB; mechanically, all specifications are identical. It does not have an adjustable air cushion. Instead, it uses a fixed NBR bumper at each end to decelerate the piston. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed.
