About the Airtac B01-SDA Dedicated Cylinder B01-SDA50X20B
The AirTAC B01-SDA50X20B is a double-acting compact cylinder engineered for space-constrained pneumatics. The B01- prefix denotes an application-dedicated (customer-specified) variant of the SDA50X20B, meaning it is mechanically identical to the base model. It delivers a robust 981.7 N push force at 0.5 MPa, utilizing a hard-anodized bore and a two-way piston seal for reliable operation.
This specific SKU features a male-thread piston rod (M18x1.5) for secure load coupling and uses a PT1/4 port. The riveted body design drastically reduces axial mounting depth compared to round-body cylinders. End-stopping relies on a fixed NBR bumper rather than an adjustable cushion, and because this unit lacks the -S magnet, it cannot host magnetic switches.

Where the Airtac B01-SDA Dedicated Cylinder B01-SDA50X20B Is Used
Injection Mold Ejection
Fits within tight mold platens to eject 50 kg plastic parts, leveraging the 20mm stroke and male M18x1.5 rod for secure tooling attachment.
Carton Flap Folding
Drives short-acting folder arms on high-speed packaging lines where the compact riveted body saves valuable axial footprint.
Pallet Diverter Gate
Actuates routing gates for heavy pallets, utilizing the 981.7 N push force to positively redirect loads without slipping.
Is the Airtac B01-SDA Dedicated Cylinder B01-SDA50X20B the Right Cylinder?
When sizing this unit, evaluate your force margins carefully. Stepping down to the SDA40 yields 628.3 N push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. For the 50mm bore, a safe working load is roughly 589 N (about 60% of the 981.7 N capacity), translating to a vertical lift of approximately 50 kg with a 2:1 safety margin. Note that a plain cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a lock or brake. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 50mm bore, 20mm stroke, PT1/4 port, no magnet, and the male M18x1.5 rod thread.
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-SDA50X20B FAQ
This double-acting cylinder generates a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. At 0.7 MPa, the push increases to 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa with a speed range of 30-500 mm/s.
The B01- prefix indicates an application-dedicated (customer-specified) variant of the SDA50X20B, sharing identical physical specs. It does not have an adjustable air cushion; instead, it uses a fixed NBR bumper at each end to decelerate the stroke. For high-energy cycles, add an external shock absorber. Additionally, this unit has no piston magnet, so it cannot accept reed or electronic switches.
