The AirTAC SDA63X45SBH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 45mm 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 SDA63X45SBH is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth compared to standard round-body units, saving valuable machine footprint in tight assemblies. This specific configuration includes a built-in piston magnet for position sensing, a male M18x1.5 threaded rod end, and high-temperature fluororubber (FKM) seals.
The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable operation. End-stop deceleration is handled by a fixed NBR bumper at each end, which is not an adjustable air cushion. Because the piston drifts when air pressure is lost or a valve is centered, an external rod lock or pilot-operated check valve is required if your application must hold a load securely in place without live pressure.

Drives ejection pins on a 150-ton injection molding press, utilizing the 1558.6 N extend force to reliably strip dense plastic parts from the tool cavity.
Pushes heavy timber pallets laterally onto a secondary packaging line, where the compact riveted body fits neatly within the 60 mm conveyor frame gap.
Secures cast aluminum engine blocks during CNC machining, leveraging the male M18x1.5 rod thread for a robust mechanical coupling to the custom jaw arm.
If you need less force, the adjacent SDA50 generates 981.7 N at 0.5 MPa, while stepping up to the SDA80 yields 2513.3 N for heavier demands. To verify your order, confirm the 63 mm bore, 45 mm stroke, PT1/4 port, male M18x1.5 rod thread, the integrated magnet, and the FKM seal option.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
The -S code denotes a built-in piston magnet compatible with AirTAC reed or electronic switches mounted in the body grooves. End damping relies on a fixed NBR bumper, not an adjustable air cushion, so you should add an external shock absorber for high-speed or high-energy loads.
