The AirTAC AirTAC SDA63X50SBH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm 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 SDA63X50SBH is a double-acting single-rod compact cylinder engineered to deliver 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. Its short riveted body significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint in tight assemblies. The bore is hard-anodized and uses a two-way piston seal for reliable operation.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, a male M18x1.5 threaded rod end for direct load coupling, and high-temperature fluororubber (FKM) seals. End-stopping is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles. Operating speed spans 30-500 mm/s.

Secures heavy cast iron engine blocks during machining operations, utilizing the 1558.6 N extend force and male M18x1.5 rod to pull a jaw clamp tight against the part profile.
Indexes empty wooden pallets into an automated packaging line, where the short 50 mm stroke and compact riveted body minimize frame interference in tight conveyor transfer zones.
Pushes metal strip into a progressive die at up to 500 mm/s, relying on the FKM seals to withstand elevated ambient heat and lubricant mist near the press bed.
When sizing this 63 mm bore actuator, consider stepping down to the SDA50 which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80 which yields 2513.3 N at the same pressure. Based on the 1558.6 N push figure, the computed safe working load is approximately 935 N (60% capacity), translating to a vertical lift capability of about 79.4 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; achieving true load holding requires adding an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 50 mm stroke, PT1/4 port, male M18x1.5 rod thread, magnet, and FKM seal option.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa, with a proof pressure rating of 1.5 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a braking lock; for high-speed cycles you should add external shock absorbers. Furthermore, it cannot hold a load if air pressure drops—you must integrate an external rod lock or pilot-operated check valve for fail-safe positioning.
