The AirTAC AirTAC SDA50X10BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 10mm 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 SDA50X10BH is a double-acting, single-rod compact cylinder engineered for tight axial mounting spaces. Its riveted assembly reduces overall length compared to round-body units, yielding a robust 981.7 N push force at 0.5 MPa. This specific configuration includes a male M18x1.5 piston rod end for secure mechanical coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The unit features a hard-anodized 50 mm bore and a 20 mm piston rod. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning external shock absorbers should be added for high-energy cycles. Operating speeds span 30-500 mm/s, and because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Secures heavy cast iron engine blocks during machining operations, utilizing the 981.7 N extend force to maintain rigid positioning against cutting forces.
Actuates a heavy mechanical gate on an automated palletizing line, where the short 10 mm stroke and FKM seals withstand occasional lubricant exposure.
Delivers a quick, high-force ejection push for molded plastic parts, leveraging the male M18x1.5 rod thread to attach custom tooling adapters securely.
When sizing this actuator, evaluate your force margins carefully. Stepping down to an SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to an SDA63 provides 1558.6 N. The 50 mm bore offers a computed safe working load of roughly 589 N (about 60% of its 981.7 N capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin.
To finalize your order, confirm the 10 mm stroke, PT1/4 port, and the male M18x1.5 rod thread. Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. If your application demands strict position holding without live pressure, 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, the push force is 1374.4 N and the pull force is 1154.5 N. The theoretical maximum push force is 200 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the -S variant for sensing capabilities. Additionally, end stops are managed by a fixed NBR bumper, not an adjustable air cushion.
