The AirTAC AirTAC SDA50X100SH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 100mm 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 SDA50X100SH is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Featuring a 50 mm bore and 100 mm stroke, this unit integrates a built-in piston magnet for position sensing alongside a fluororubber (FKM) seal variant for enhanced thermal and oil resistance. The hard-anodized bore and two-way piston seal ensure durable, long-lasting performance.
Its short riveted body significantly reduces axial mounting depth compared to conventional round-body cylinders, making it ideal for space-constrained machinery. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke end; because this is not an adjustable air cushion, high-energy cycles may require an external shock absorber. The body includes standard grooves for AirTAC reed or electronic switches, and the PT1/4 porting pairs with a 20 mm rod to handle substantial loads.

Drives the flap-folding arms on high-speed corrugated box palletizers, where the 981.7 N output securely tucks heavy cardboard flaps prior to sealing.
Actuates sorting gates on beverage conveyor lines to reroute glass or PET bottles, utilizing the 100 mm stroke to clear the passing product profile.
Serves as a compact secondary ejector on injection molding machines, pushing finished plastic parts off the tool face within a tight machinery footprint.
When sizing this actuator, stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. The SDA50X100SH offers a 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. A plain compact cylinder drifts if air pressure drops or the valve centers, as the fixed bumper only decelerates near the stroke end rather than locking the rod; for suspended loads, add an external rod lock or pilot-operated check valve. To order, confirm the 50 mm bore, 100 mm stroke, PT1/4 port, female M10x1.5 rod thread, plus the S magnet and H FKM seal options.
Quick checklist
This 50 mm bore cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, increasing to 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion or a locking brake. This specific model includes the -H fluororubber (FKM) seal variant for improved oil and heat resistance, and the -S magnet allows tracking by AirTAC reed or electronic switches.
