About the Airtac B01-SDA Dedicated Cylinder B01-SDA25X5
The AirTAC B01-SDA25X5 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA25X5, meaning it is mechanically identical to the standard line but grouped for specific customer builds. It delivers a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa.
Designed to save axial mounting depth where round-body units fail to fit, the short riveted body incorporates a hard-anodized bore and a two-way piston seal. This specific SKU lacks a piston magnet and therefore cannot host magnetic switches. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, so high-energy cycles require slowing the approach or adding external shock absorbers.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X5 Is Used
PCB Edge Clamping
Provides 245.4 N of clamping force at 0.5 MPa to secure circuit boards within an electronics assembly fixture without exceeding the 5 mm travel limit.
Film Seal Jaw Actuation
Drives the short 5 mm stroke of a vertical form-fill-seal packaging jaw, utilizing the compact riveted body to minimize axial machine footprint.
Short-Stroke Part Ejection
Ejects small machined aluminum components from a CNC chuck using a 10 mm rod, relying on the fixed NBR bumper to absorb the sudden end-stop impact.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X5 the Right Cylinder?
When sizing this 25 mm bore, stepping down to the SDA20 yields 157.1 N of push force at 0.5 MPa, while stepping up to the SDA32 provides 402.1 N. This B01-SDA25X5 provides a safe working load of roughly 147 N (about 60% of its 245.4 N capacity) and can vertically lift approximately 12.5 kg with a 2:1 safety margin. To order, confirm the 5 mm stroke, M5x0.8 port, female M5x0.8 rod thread, and the absence of the S magnet option. Note that a plain cylinder drifts when air is lost or the valve is centered; holding a load requires an external rod lock or 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-SDA25X5 FAQ
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, 343.6 N push and 288.6 N pull at 0.7 MPa, with a theoretical maximum push of 50 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, runs at 30-500 mm/s, and functions in temperatures from -20 to +70 C.
The B01- prefix designates an application-dedicated (customer-specified) variant of the SDA25X5, sharing identical physical specs and sizing. It does not have an adjustable air cushion; instead, a fixed NBR bumper decelerates the piston at stroke end. Additionally, this specific SKU lacks the S magnet option, so it cannot support reed or electronic switches.
