The AirTAC AirTAC SDA63X65B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 65mm 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 SDA63X65B is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N of push force at 0.5 MPa. Its riveted body assembly integrates the barrel, rear cover, piston, and rod into a highly abbreviated package, drastically reducing axial mounting depth compared to conventional round-body units. This space efficiency makes it ideal for machinery where footprint reduction is critical.
This specific SKU features a male M18x1.5 threaded piston rod for robust load coupling, paired with a 20 mm rod diameter and PT1/4 air ports. The bore is hard-anodized for longevity, and end-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this configuration omits the piston magnet, so position sensing is not supported without the -S variant.

Drives the ejection plate inside a plastics molding machine, utilizing the 65 mm stroke to safely push finished parts out of the tool cavity.
Deploys at the end of a corrugated box erecting line to fold major top flaps prior to sealing, fitting within tight machine frames.
Positions back-gauge fingers on a sheet metal press brake, providing high push force to maintain alignment against heavy steel blanks.
When sizing this actuator, evaluate your force requirements against adjacent bores: the SDA50 provides 981.7 N of push at 0.5 MPa, while the larger SDA80 yields 2513.3 N at the same pressure. For this 63 mm bore, a safe working load is approximately 935 N (about 60% of the 1558.6 N figure), translating to a vertical lift capacity of roughly 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 near its end and does not function as a locking brake. If your application demands position holding without live pressure, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 65 mm stroke, PT1/4 porting, male M18x1.5 rod thread, and the absence of a sensor magnet.
Quick checklist
This double-acting cylinder generates 1558.6 N of push and 1401.5 N of pull at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No, end-of-stroke deceleration relies solely on a fixed NBR bumper, which is not field-adjustable; for high kinetic energy loads, use an external shock absorber. Additionally, this specific SKU lacks the internal magnet, so it cannot accept AirTAC reed or electronic switches without upgrading to the -S variant.
