About the Airtac B01-SDA Dedicated Cylinder B01-SDA50X25
The AirTAC B01-SDA50X25 is a double-acting, single-rod compact cylinder delivering 981.7 N of push force at 0.5 MPa. The leading B01- prefix denotes an application-dedicated (customer-specified) variant of the standard SDA50X25, retaining the exact same mechanical specifications. Its short riveted body merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth where a round-body unit would never fit.
This 50 mm bore model features a 20 mm piston rod and a PT1/4 port. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion. Because this specific SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches. For high-speed cycling, adding an external shock absorber helps manage impact energy.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA50X25 Is Used
Carton Flap Folding
Drives short-stroke folding arms on automated packaging lines, using its 981.7 N thrust to tuck heavy cardboard flaps before tape sealing.
Pallet Diverter Gate
Actuates routing gates on conveyor systems to redirect loaded pallets, fitting into tight frame clearances due to the minimal axial riveted body length.
Injection Mold Ejector
Provides a compact 25 mm kick-out stroke to free molded plastic parts from tooling, saving machine footprint compared to standard profile cylinders.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA50X25 the Right Cylinder?
When sizing this actuator, step down to the SDA40 which provides 628.3 N of push at 0.5 MPa, or step up to the SDA63 yielding 1558.6 N at the same pressure. This B01-SDA50X25 yields a safe working load of roughly 589 N (about 60 percent 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, 25 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the absence of a sensor magnet. Note that a plain compact cylinder drifts when air pressure is lost or the valve centers; the fixed bumper only slows the piston near the end of travel and does not function as a locking brake. If your application must hold a load without live pressure, 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-SDA50X25 FAQ
This double-acting 50 mm bore cylinder provides 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 is 200 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
The B01- prefix indicates an application-dedicated (customer-specified) line of the base SDA50X25, meaning it is mechanically identical to the standard catalog model. This specific SKU does not include a piston magnet (-S option), so it cannot host AirTAC reed or electronic switches. End-stopping is handled by a fixed NBR bumper rather than an adjustable air cushion.
