About the Airtac B01-SDA Dedicated Cylinder B01-SDA63X20B
The AirTAC B01-SDA63X20B is a double-acting single-rod compact cylinder. The leading "B01-" prefix marks this as an application-dedicated (customer-specified) variant of the base SDA63X20B, meaning it is mechanically identical to the standard line but grouped for specific build requirements. It delivers a robust 1558.6 N push and 1401.5 N pull force at 0.5 MPa.
The riveted body design significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. This specific SKU features a male M18x1.5 piston rod thread (denoted by the B option) for secure mechanical coupling to your load. Because it lacks the S magnet option, it cannot host magnetic switches. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, so high-energy cycles may require external shock absorbers.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA63X20B Is Used
Injection Mold Ejection
Drives short-stroke ejection pins in plastic injection molding machines, utilizing the 1558.6 N extend force to break parts free from tight molds.
Heavy Package Diverting
Actuates heavy-duty routing gates on logistics conveyor lines, where the compact riveted body fits into tight transfer gaps and pushes dense parcels reliably.
Press Brake Tooling
Positions lower tooling beds on metal press brakes, using the 20 mm stroke for precise height adjustments while handling high lateral stiffness requirements.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA63X20B the Right Cylinder?
This 63 mm bore generates 1558.6 N push at 0.5 MPa, yielding a safe working load around 935 N (roughly 60 percent of capacity) and a vertical lift capability of about 79.4 kg with a 2:1 safety margin. If you need less force, the SDA50 provides 981.7 N at 0.5 MPa; stepping up to the SDA80 offers 2513.3 N. When ordering, confirm the 63 mm bore, 20 mm stroke, PT1/4 port, male M18x1.5 rod thread, and no magnet. Note that a plain cylinder drifts when air is lost or the valve is centered—the fixed bumper only decelerates near stroke end, so install an external rod lock or pilot-operated check valve if the load must be held.
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-SDA63X20B FAQ
This 63 mm bore cylinder delivers 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push is 318 kgf at the 1.0 MPa operating pressure limit.
The B01- prefix indicates an application-dedicated (customer-specified) variant of the SDA63X20B, sharing identical specifications. It does not have an adjustable air cushion; it uses a fixed NBR bumper at each end to decelerate the stroke. For high-speed or high-energy loads, add an external shock absorber.
