About the Airtac B01-SDA Dedicated Cylinder B01-SDA20X25
The AirTAC B01-SDA20X25 is a double-acting, single-rod compact cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the standard SDA20X25, meaning it is mechanically identical to the base model. It delivers 157.1 N of push force and 131.9 N of pull force at 0.5 MPa, utilizing an 8 mm piston rod and an M5x0.8 air port.
Its short riveted body drastically reduces axial mounting depth compared to round-body alternatives, making it ideal for tight machine footprints. The bore is hard-anodized for longevity, and deceleration at stroke ends is handled by a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot directly mount AirTAC position switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA20X25 Is Used
PCB Depaneling Router
Provides the 157.1 N push at 0.5 MPa required to actuate the cutting head or clamping gate on a printed circuit board routing machine, fitting neatly within the electronics manufacturing cell.
Carton Flap Folder
Uses its 25 mm stroke to rapidly fold minor box flaps on a continuous packaging conveyor, relying on the fixed NBR bumper to absorb the impact of high-speed cycling.
Lab Sample Dispenser
Drives a 8 mm piston rod to press a pipette or valve mechanism in automated analytical equipment, where the compact riveted body saves critical axial depth in a crowded instrument chassis.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA20X25 the Right Cylinder?
When sizing this unit, consider stepping down to the SDA16, which provides 100.5 N of push at 0.5 MPa, or moving up to the SDA25, which yields 245.4 N at the same pressure. Based on the 157.1 N push figure, the safe working load is approximately 94 N (about 60% capacity), translating to a vertical lift of roughly 8 kg with a 2:1 safety margin. To order, confirm the 20 mm bore, 25 mm stroke, M5x0.8 port, female M4x0.7 rod thread, and the absence of a magnet. Remember that a plain compact cylinder drifts when air pressure is lost or a valve is centered; the fixed bumper only slows the piston near the end of travel and does not function as a locking brake. If your application requires position holding without live pressure, you must 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-SDA20X25 FAQ
This 20 mm bore 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 is 32 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 from 30 to 500 mm/s.
The B01- prefix designates an application-dedicated (customer-specified) build that is mechanically identical to the standard SDA20X25. Because this specific SKU lacks the -S option, it has no piston magnet and cannot support AirTAC reed or electronic switches. If sensing is required, you must select the -S variant.
