The AirTAC Airtac B01-SDA Dedicated Cylinder B01-SDA50X40SB is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 40mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC B01-SDA50X40SB is a double-acting single-rod compact cylinder. The leading B01- prefix marks this as an application-dedicated (customer-specified) variant of the base SDA50X40SB, meaning it is mechanically identical to the standard model but grouped for specific customer builds. Delivering 981.7 N of push force at 0.5 MPa, it utilizes a short riveted body that saves axial mounting depth where a round-body cylinder cannot fit.
This 50 mm bore unit features a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It includes a male M18x1.5 piston rod thread (-B) for secure load coupling, a hard-anodized bore, and a fixed NBR bumper at each end to decelerate the stroke end. Note that this bumper is not an adjustable air cushion, so high energy cycles may require an external shock absorber.

Pushes medium-weight cartons off a sorting line using 981.7 N of thrust, fitting into tight transfer station footprints.
Ejects formed plastic parts from a mold cavity using the male M18x1.5 rod end, saving axial depth on the press platen.
Acts as a height stopper for incoming pallets on a packaging cell, triggering an AirTAC electronic switch upon contact.
When sizing this unit, step down to the SDA40 which provides 628.3 N push at 0.5 MPa, or step up to the SDA63 which yields 1558.6 N push at 0.5 MPa. Based on the 981.7 N push figure at 0.5 MPa, the safe working load is approximately 589 N (about 60 percent capacity), translating to a vertical lift capability of roughly 50 kg with a 2:1 safety margin. To confirm your ordering essentials for this application-dedicated variant: specify the 50 mm bore, 40 mm stroke, PT1/4 port, built-in magnet, and male M18x1.5 rod thread. A plain compact cylinder does not hold its load when air is lost or the valve is centered, as the piston drifts and the fixed bumper only decelerates near the stroke end; if your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. It operates at 0.15-1.0 MPa with a speed range of 30-500 mm/s.
The B01- prefix simply marks this as an application-dedicated (customer-specified) variant of the SDA50X40SB; it shares the exact same physical specs. Instead of an adjustable air cushion, it uses a fixed NBR bumper at each end to decelerate the stroke. For high-speed cycles, add an external shock absorber.
