The AirTAC AirTAC SDA50X50SBH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 50mm 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 SDA50X50SBH is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to traditional round-body units, saving valuable machine footprint. The bore is hard-anodized and uses a two-way piston seal for optimal pneumatic efficiency.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, a male M18x1.5 threaded rod end for secure load coupling, and FKM seals for enhanced thermal and oil resistance. End-stopping is handled by a fixed NBR bumper that decelerates the piston near stroke limits rather than acting as an adjustable air cushion.

Drives the folding mechanism on continuous packaging lines, utilizing the 981.7 N extend force to swiftly close heavy cardboard flaps during high-speed case erecting.
Actuates routing gates on material handling conveyors, where the short riveted body fits neatly within tight side-frame clearances to redirect 50 kg pallets.
Secures heavy cast iron blocks inside machining centers, leveraging the male M18x1.5 rod end for robust mechanical coupling to the fixture jaw.
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 at the same pressure. Based on the 981.7 N output, the safe working load is approximately 589 N (60% capacity), translating to a vertical lift capability of about 50 kg with a 2:1 safety margin. Keep in mind that a standard 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. To maintain position, integrate an external rod lock or a pilot-operated check valve.
To order, confirm the 50 mm bore, 50 mm stroke, PT1/4 port, male M18x1.5 rod thread, the integrated magnet, and the FKM seal option.
Quick checklist
This 50 mm bore double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa, or 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-energy cycles, slow the approach or add an external shock absorber. Additionally, it will not hold a load if air is lost; the piston drifts, so an external rod lock or pilot-operated check valve is required for position holding.
