Airtac B01-SDA Dedicated Cylinder B01-SDA40X55
The AirTAC Airtac B01-SDA Dedicated Cylinder B01-SDA40X55 is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 55mm 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-SDA40X55
The AirTAC B01-SDA40X55 is a double-acting single-rod compact cylinder. The leading "B01-" prefix designates an application-dedicated (customer-specified) variant of the base SDA40X55, meaning it is mechanically identical to the standard line 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, operating within a 0.15-1.0 MPa pressure range.
Its short riveted body significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. The 16 mm piston rod features an M8x1.25 female thread, and the barrel integrates grooves for reed or electronic switches—though this specific SKU lacks the piston magnet, so sensing is not supported without the -S option. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, decelerating the piston near stroke end without acting as a lock.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X55 Is Used
PCB Edge Routing
Ideal for routing machine clamping arms where 628.3 N of push force secures circuit boards, utilizing the 55 mm stroke to clear the cutting head.
Carton Flap Folding
Drives mechanical flap folders on packaging lines, using the compact riveted body to fit within tight conveyor side frames without axial bulk.
Press Fit Bushings
Presses small bronze bushings into housings on an assembly fixture, relying on the 16 mm rod to deliver consistent 527.8 N retraction force.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X55 the Right Cylinder?
When sizing this unit, consider stepping down to the SDA32, which yields 402.1 N of push at 0.5 MPa, or moving up to the SDA50, which provides 981.7 N. The 40 mm bore here offers a safe working load of roughly 377 N (about 60% of its 628.3 N capacity), translating to a vertical lift capability of approximately 32 kg with a 2:1 safety margin. Confirm your ordering essentials: 40 mm bore, 55 mm stroke, PT1/8 port, female rod thread, and no magnet.
Be aware 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 near the stroke end rather than locking the position. If your application requires a held load 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-SDA40X55 FAQ
This double-acting cylinder provides 628.3 N push and 527.8 N pull at 0.5 MPa, and 879.6 N push at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
The B01- prefix simply marks this as an application-dedicated (customer-specified) variant of the SDA40X55; it shares the exact same physical specs. It does not have an adjustable air cushion. Instead, it uses a fixed NBR bumper at each end to absorb impact. For high-speed or high-energy cycles, add an external shock absorber or slow the approach speed.
