About the Airtac B01-SDA Dedicated Cylinder B01-SDA40X80
The AirTAC B01-SDA40X80 is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated, customer-specified variant of the standard SDA40X80, meaning it is mechanically identical to the base model. It delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa, operating within a 0.15-1.0 MPa pressure range.
The short riveted body integrates the barrel, rear cover, piston, and rod to minimize axial mounting depth where a round-body unit will not fit. This 40 mm bore features a 16 mm piston rod, PT1/8 air ports, and a female M8x1.25 rod-end thread. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, so for high-energy cycles you should slow the approach or add an external shock absorber. This SKU lacks a piston magnet and cannot host a magnetic switch.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA40X80 Is Used
Carton Erector Flaps
Folds corrugated box flaps on a continuous packaging line, utilizing the 80 mm stroke and 628.3 N extend force to cleanly clear the mechanism for the next carton.
Pallet Diverter Gate
Actuates a routing gate to redirect heavy pallets between conveyor lanes, taking advantage of the space-saving riveted body to fit within tight conveyor frame depths.
Injection Mold Ejector
Pushes finished plastic parts out of an injection molding cavity, where the 16 mm rod and fixed NBR bumper reliably absorb the repetitive end-stop impact.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA40X80 the Right Cylinder?
When sizing this unit, evaluate your neighbours: stepping down to the SDA32 yields 402.1 N push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For this 40 mm bore, the safe working load is approximately 377 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. Confirm your ordering essentials: 40 mm bore, 80 mm stroke, PT1/8 port, female rod thread, and no magnet. Note that a plain compact cylinder drifts when air is lost or the valve is centred; the fixed bumper only decelerates near stroke end and does not act as a lock. If your application must hold a load without live pressure, specify 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-SDA40X80 FAQ
This double-acting 40 mm bore cylinder provides a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum push force is 128 kgf at 1.0 MPa. It operates on filtered air at 0.15-1.0 MPa with a speed range of 30-500 mm/s.
The B01- prefix designates an application-dedicated, customer-specified line of the base SDA40X80; mechanically, the bore, stroke, and seals are identical. Instead of an adjustable air cushion, it uses a fixed NBR bumper at each end to decelerate the stroke. For high-speed or high-energy loads, you should slow the approach or install an external shock absorber.
