About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X10S
The AirTAC B01-SDA20X10S is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA20X10S; mechanically, it is identical, delivering 157.1 N push and 131.9 N pull at 0.5 MPa. Its short riveted body saves valuable axial mounting depth where a round-body or profile cylinder will not fit.
This 20 mm bore unit features an 8 mm piston rod and M5x0.8 port. Equipped with a built-in piston magnet (-S), it supports AirTAC reed or electronic switches via body grooves. A fixed NBR bumper at each end decelerates the stroke end, and the hard-anodized bore ensures durable, low-friction operation.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X10S Is Used
PCB Edge-Guiding
Provides precise 10 mm lateral positioning on an SMT pick-and-place conveyor, utilizing the 157.1 N extend force to square panels before component placement.
Blister Pack Sealing
Drives a short 10 mm clamping stroke on a rotary blister packaging machine, saving axial depth while delivering enough hold for card sealing operations.
Lab Dispenser Valve
Acts as the pneumatic actuator for a micro-fluidic dispensing head, where the 8 mm rod and compact body fit tightly within an analytical instrument chassis.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X10S the Right Cylinder?
When sizing this actuator, stepping down to the SDA16 yields 100.5 N push at 0.5 MPa, while stepping up to the SDA25 provides 245.4 N. For this 20 mm bore, the safe working load is roughly 94 N (about 60% of the 157.1 N figure), allowing a vertical lift of approximately 8 kg with a 2:1 margin. Ensure you specify the 10 mm stroke, M5x0.8 port, female rod thread, and the required magnet.
Note that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centred; the piston drifts until the bumper catches it. For suspended loads, integrate an external rod lock or pilot-operated check valve. The fixed NBR bumper is not an adjustable air cushion, so add external shock absorbers for high-energy impacts.
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-SDA20X10S FAQ
This 20 mm bore actuator 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 is 32 kgf at 1.0 MPa. It operates at 30-500 mm/s with a maximum standard stroke limit of 100 mm.
The B01- prefix denotes an application-dedicated (customer-specified) line of the standard SDA20X10S, sharing identical specifications. It uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. The -S indicates a built-in magnet for reed or electronic switches.
