The AirTAC AirTAC SDA50X15BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 15mm 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 SDA50X15BH is a double-acting, single-rod compact cylinder engineered with a 50 mm bore and 15 mm stroke. It generates 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. This specific SKU is configured with a male M18x1.5 piston rod end for secure mechanical load coupling and fluororubber (FKM) seals for enhanced thermal and oil resistance. The hard-anodized bore and two-way piston seal ensure durable, leak-free operation.
Its riveted body design drastically reduces axial mounting depth compared to round-body units, making it highly effective for tight machine footprints. The cylinder relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Because this configuration omits the -S magnet, it cannot support magnetic position sensing.

Secures heavy cast iron engine blocks during machining operations, utilizing the 981.7 N extend force and FKM seals to withstand cutting fluid exposure.
Actuates the release mechanism in automated palletizing lines where the short 15 mm stroke and space-saving riveted body fit within tight conveyor frames.
Pushes formed sheet metal parts out of progressive dies, leveraging the male M18x1.5 rod end for high-strength tooling attachment.
When sizing this unit, evaluate your force margins carefully. Stepping down to the SDA40 reduces the 0.5 MPa push capacity to 628.3 N, whereas stepping up to the SDA63 increases it to 1558.6 N. For the SDA50X15BH, the safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capability of roughly 50 kg with a 2:1 safety margin. Ensure your order specifies the PT1/4 port, male M18x1.5 rod thread, and FKM seal option.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The fixed bumper only absorbs impact near the stroke end and does not function as a locking brake. If your application requires strict position holding on loss of air, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, push is 1374.4 N and pull is 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the -S variant for sensing capabilities. Additionally, end stopping is handled by a fixed NBR bumper, not an adjustable cushion.
