The AirTAC AirTAC SDA63X65SB 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 SDA63X65SB 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 design drastically reduces axial mounting depth compared to round-body alternatives, making it highly effective for machinery where space footprint is critical. The unit includes a built-in piston magnet for position sensing and a male M18x1.5 threaded rod end for secure load coupling.
This model features a 63 mm bore, a 65 mm stroke, and a PT1/4 port. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the piston near stroke limits. For high kinetic energy applications, operators should add an external shock absorber or slow the approach speed. The body incorporates sensor grooves compatible with AirTAC reed or electronic switches, operating effectively at speeds between 30 and 500 mm/s.

Provides robust clamping for sheet metal panels in robotic welding cells, utilizing the 1558.6 N extend force to maintain rigid part alignment under heavy spot-welding pressure.
Transitions filled cartons onto outbound pallet lines, where the short riveted body saves valuable axial space within dense conveyor networks.
Ejects formed metal components from stamping presses, using the 20 mm rod and male M18x1.5 thread to securely attach heavy-duty ejector tooling.
When sizing this actuator, stepping down to the SDA50 yields 981.7 N of push force at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. The SDA63X65SB offers a computed safe working load of roughly 935 N (about 60% of its 1558.6 N capacity) and can vertically lift approximately 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 65 mm stroke, PT1/4 port, built-in magnet (S), and male M18x1.5 rod thread (B). Remember that a standard compact cylinder will not hold a load if air pressure drops or the valve is centered; the piston will drift. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
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 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable cushion or a locking brake. For high-speed impacts, add an external shock absorber. The S option denotes a built-in piston magnet designed to trigger AirTAC reed or electronic switches along the body grooves.
