About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X75B
The B01-SDA40X75B is an AirTAC double-acting compact cylinder engineered for space-constrained machinery. The leading B01- prefix designates an application-dedicated (customer-specified) variant of the base SDA40X75B, meaning it is mechanically identical to the standard model but grouped for specific customer builds. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa.
Featuring a short riveted body, this unit saves substantial axial mounting depth compared to traditional round-body cylinders. It operates with a 16 mm piston rod and a male M14x1.5 thread end for direct load coupling. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host magnetic switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X75B Is Used
Injection Mold Ejection
Drives ejection pins in compact injection molding machines where axial depth is restricted, utilizing the 628.3 N extend force to reliably strip finished plastic parts.
Carton Flap Folding
Folds corrugated carton flaps on high-speed packaging lines, using the male M14x1.5 rod end for secure mechanical linkage and the short body to fit tight conveyor gaps.
Pallet Diverting
Pushes pallets onto secondary conveyor tracks in material handling systems, benefiting from the 527.8 N retract force to quickly reset the diverter arm.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X75B the Right Cylinder?
When sizing this 40 mm bore actuator, consider stepping down to the SDA32 which yields 402.1 N of push force at 0.5 MPa, or stepping up to the SDA50 which provides 981.7 N at the same pressure. For the 628.3 N output at 0.5 MPa, the safe working load is approximately 377 N (about 60% of capacity), translating to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. Confirm your ordering essentials: 40 mm bore, 75 mm stroke, PT1/8 port, male M14x1.5 rod thread, and no sensor magnet. Because a plain double-acting cylinder drifts when air is lost or a valve centers, add an external rod lock or pilot-operated check valve if the application requires strict load holding.
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-SDA40X75B FAQ
This double-acting cylinder generates a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, the push force is 879.6 N. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa and travels at speeds between 30-500 mm/s.
The B01- prefix simply indicates an application-dedicated (customer-specified) variant of the SDA40X75B, with no mechanical or dimensional changes to the base cylinder. This specific SKU does not have a piston magnet and cannot support reed or electronic switches. To add sensing capabilities, you would need the -S magnet option on a different order code. Additionally, it uses a fixed NBR bumper for end deceleration rather than an adjustable cushion.
