Airtac B01-SDA Dedicated Cylinder B01-SDA20X20B
The AirTAC Airtac B01-SDA Dedicated Cylinder B01-SDA20X20B is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 20mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.

About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20B
The AirTAC B01-SDA20X20B is a double-acting single-rod compact cylinder delivering 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. The B01- prefix designates this as an application-dedicated (customer-specified) variant of the standard SDA20X20B, meaning it is mechanically identical to the base model but grouped for specific industry builds. It features a hard-anodized bore and a two-way piston seal for reliable pneumatic performance.
This unit includes the -B option, providing a male M6x1.0 threaded piston rod end for secure mechanical coupling to your load. The short riveted body significantly reduces axial mounting depth compared to round-body cylinders, making it ideal for tight machine footprints. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke, and the body lacks a piston magnet, so it cannot support magnetic sensing.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20B Is Used
PCB Board Clamping
Provides 157.1 N of push force to secure delicate printed circuit boards during automated soldering or inspection processes without crushing the substrate.
Carton Flap Folding
Uses the 20 mm stroke and male M6x1.0 rod end to actuate small folding arms on packaging lines, tucking cardboard flaps prior to sealing.
Lab Dispenser Positioning
Moves fluid dispensing nozzles with precise 20 mm travel in compact laboratory automation equipment where axial space is highly restricted.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X20B the Right Cylinder?
When sizing this actuator, stepping down to the SDA16 yields 100.5 N of push at 0.5 MPa, while stepping up to the SDA25 provides 245.4 N, allowing you to adjust if the 157.1 N output is too high or too low. Based on the 0.5 MPa push figure, the safe working load is approximately 94 N (about 60% capacity), translating to a vertical lift capability of roughly 8 kg with a 2:1 safety margin. To confirm your ordering essentials for this application-dedicated line: specify the 20 mm bore, 20 mm stroke, M5x0.8 port, male M6x1.0 rod thread, and no magnet. Note that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than locking the position. For applications requiring position holding without live pressure, an external rod lock or pilot-operated check valve is required.
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-SDA20X20B FAQ
This 20 mm bore double-acting cylinder generates 157.1 N push and 131.9 N pull at 0.5 MPa, and 219.9 N push at 0.7 MPa. The theoretical maximum push force is 32 kgf at 1.0 MPa. It operates at speeds between 30-500 mm/s.
The B01- prefix indicates this is an application-dedicated (customer-specified) variant of the SDA20X20B, sharing the exact same physical specs. It does not have an adjustable air cushion; instead, a fixed NBR bumper absorbs impact at the stroke ends. For high-speed cycling, you should add an external shock absorber or slow the approach speed.
