Airtac B01-SDA Dedicated Cylinder B01-SDA40X30
The AirTAC Airtac B01-SDA Dedicated Cylinder B01-SDA40X30 is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 30mm stroke, PT1/8 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-SDA40X30
The AirTAC B01-SDA40X30 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA40X30, meaning it is mechanically identical to the standard model but grouped for specific customer builds. It delivers 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. The short riveted body drastically reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint.
This 40 mm bore unit features a 16 mm piston rod and PT1/8 air ports. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorbers. Because this specific SKU lacks the -S option, it has no piston magnet and cannot support magnetic sensing. The theoretical maximum push capacity reaches 128 kgf at 1.0 MPa.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X30 Is Used
CNC Fixture Clamping
Secures aluminum engine blocks onto machining centers. The 628.3 N extend force at 0.5 MPa holds parts firmly against spindle vibration during milling operations.
Carton Flap Folding
Drives mechanical arms to tuck top flaps on corrugated shipping boxes. Its 30 mm stroke and compact riveted body fit neatly within tight conveyor side frames.
Injection Mold Ejection
Pushes plastic runner assemblies clear of molding tools. The fixed NBR bumper absorbs the end stop, though high-speed ejection cycles may need external shock absorption.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X30 the Right Cylinder?
When sizing this actuator, consider stepping down to the SDA32 which yields 402.1 N of push at 0.5 MPa for lighter loads, or moving up to the SDA50 which provides 981.7 N if your application demands greater thrust. For the B01-SDA40X30, the computed safe working load is approximately 377 N (about 60% of the 628.3 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. Confirm your ordering essentials: 40 mm bore, 30 mm stroke, PT1/8 port, female M8x1.25 rod thread, and no sensor magnet. Note that a plain cylinder drifts when air is lost or the valve is centered, so an external rod lock or pilot-operated check valve is required to hold a load securely without live pressure.
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-SDA40X30 FAQ
This double-acting 40 mm bore cylinder provides 628.3 N push and 527.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 879.6 N. The theoretical maximum push is 128 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles 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) variant of the standard SDA40X30, sharing identical mechanical specifications. Because this particular SKU lacks the -S magnet option, it cannot accept AirTAC reed or electronic switches. You would need to specify the -S option for position sensing capabilities.
