The AirTAC AirTAC SDA63X55B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 55mm 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 SDA63X55B 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 riveted body assembly significantly reduces axial mounting depth compared to conventional round-body units, making it highly effective for conserving machine footprint in tight assemblies. The bore is hard-anodized and utilizes a two-way piston seal for reliable pneumatic performance.
This specific configuration includes a male M18x1.5 threaded piston rod for robust mechanical coupling to your load. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Drives ejection pins on mid-sized plastic injection molding machines where the short riveted body minimizes interference with the mold base.
Actuates folding and sealing mechanisms on automated packaging lines, utilizing the 1558.6 N extend force to securely close heavy corrugated flaps.
Raises and lowers diverting gates on pallet handling conveyors, with the male M18x1.5 rod end providing a rigid connection to the lifting linkage.
When sizing this 63 mm bore actuator, consider stepping down to the SDA50, which provides 981.7 N of push force at 0.5 MPa, or stepping up to the SDA80, which yields 2513.3 N at the same pressure. Based on the 1558.6 N output, 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 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, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 55 mm stroke, PT1/4 porting, and the male M18x1.5 rod thread.
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. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this model uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, because this SKU lacks the -S suffix, it has no piston magnet and cannot support AirTAC reed or electronic switches.
