Airtac B01-SDA Dedicated Cylinder B01-SDA25X25
The AirTAC Airtac B01-SDA Dedicated Cylinder B01-SDA25X25 is a genuine double-acting COMPACT (thin) air cylinder with a Ø25mm bore and 25mm 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-SDA25X25
The AirTAC B01-SDA25X25 is a double-acting, single-rod compact cylinder. The B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA25X25, 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. The short riveted body significantly reduces axial mounting depth, making it ideal for machinery where a standard round-body unit will not fit.
This 25 mm bore model features a 10 mm piston rod and an M5x0.8 air port. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke. Note that this specific SKU lacks a piston magnet, so it cannot directly host AirTAC reed or electronic switches without upgrading to the -S option. The theoretical maximum push capacity is 50 kgf at 1.0 MPa.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA25X25 Is Used
PCB Routing Fixture
Clamps printed circuit boards during routing operations. The 25 mm stroke provides precise travel while the compact body minimizes footprint in dense electronics assembly cells.
Carton Flap Folding
Actuates side flaps on small packaging cartons prior to sealing. The 245.4 N push force at 0.5 MPa easily overcomes cardboard resistance without crushing the box structure.
Sorter Diverter Arm
Pushes lightweight parcels off a main conveyor belt. Operating safely at 147 N (60% of the 0.5 MPa capacity), it handles rapid 25 mm shifts without requiring extensive axial depth.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA25X25 the Right Cylinder?
When sizing this unit, consider stepping down to the SDA20, which provides 157.1 N of push force at 0.5 MPa, or stepping up to the SDA32, which yields 402.1 N at the same pressure. Based on the 245.4 N output at 0.5 MPa, the safe working load is approximately 147 N (about 60% capacity), translating to a vertical lift of roughly 12.5 kg with a 2:1 safety margin. To finalize your order, confirm the 25 mm bore, 25 mm stroke, M5x0.8 port, female rod-end thread (M5x0.8), and the absence of a sensor magnet.
Keep in mind 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 NBR bumper only decelerates it near the stroke end rather than acting as a lock. 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-SDA25X25 FAQ
This double-acting cylinder generates a push force of 245.4 N and a pull force of 206.2 N at 0.5 MPa. At 0.7 MPa, the push increases to 343.6 N. The theoretical maximum push is 50 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 of 30-500 mm/s.
The B01- prefix designates an application-dedicated (customer-specified) line of the base SDA25X25, sharing identical physical specs and dimensions. This specific SKU does not include a piston magnet, so it cannot support AirTAC reed or electronic switches. You would need the -S option variant to enable sensing capabilities.
