The AirTAC SDA63X40B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 40mm 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 SDA63X40B is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly unites the barrel, rear cover, piston, and rod into a highly shortened unit, significantly reducing axial mounting depth compared to conventional round-body designs. This space efficiency is critical when machine footprints are tight.
This specific SKU features a male-thread M18x1.5 piston rod for robust mechanical coupling to your load. The bore is hard-anodized and uses a two-way piston seal, operating at speeds from 30 to 500 mm/s. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy cycles.

Drives the ejector pins on a mid-tonnage injection molding machine, utilizing the 1558.6 N extend force to break plastic parts free from the mold cavity efficiently.
Acts as a hardened back-gauge stopper block in a hydraulic sheet metal bending press, providing rigid resistance with its 20 mm diameter rod during heavy material positioning.
Folds corrugated cardboard flaps on a high-speed end-of-line palletizer, where the shortened riveted body prevents interference with adjacent conveyor tracking.
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa; stepping up, the SDA80 yields 2513.3 N at the same pressure. 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 piston near stroke end and does not function as a locking brake. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 63 mm bore, 40 mm stroke, PT1/4 port, no sensor magnet, 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. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 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 supports a speed range of 30-500 mm/s.
No, this specific SKU lacks the built-in piston magnet, so it cannot trigger AirTAC reed or electronic switches. To add sensing capabilities, you must select the -S option code. Additionally, this unit features a male M18x1.5 threaded rod end (denoted by the B code) rather than the default female M10x1.5 thread.
