The AirTAC AirTAC SDA63X40SB 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 SDA63X40SB is a double-acting, single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to traditional round-body units, saving valuable machine footprint in tight spaces. The unit includes a built-in piston magnet (-S) for position sensing and a male-thread piston rod (-B).
This 63 mm bore model features a 20 mm piston rod, PT1/4 air ports, and a fixed NBR bumper at each end to decelerate the stroke. The bumpers are not field-adjustable, so for high-energy cycles you should slow the approach or add an external shock absorber. The integrated magnet supports AirTAC reed or electronic switches along the body grooves for precise end-position detection.

Drives ejector pins on a 150-ton injection molding press, utilizing the 1558.6 N extend force to reliably strip finished plastic parts from the tool cavity.
Raises and lowers a tiered palletizing platform in a packaging line, where the short riveted body minimizes axial height and the male M18x1.5 rod secures the heavy lifting fork.
Actuates a heavy-duty swing clamp to hold aluminum engine blocks during CNC machining, relying on the 1401.5 N retract force to maintain grip against cutting vibration.
This 63 mm bore generates 1558.6 N of push at 0.5 MPa, yielding a safe working load around 935 N (60% capacity) and a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. If you need less force, the adjacent SDA50 provides 981.7 N at 0.5 MPa; stepping up to the SDA80 offers 2513.3 N for heavier demands. A standard SDA does not hold its load if air pressure drops or the valve centers—the piston will drift, as the fixed bumper only decelerates near the end of travel. For suspended or vertical loads, incorporate an external rod lock or a pilot-operated check valve. When ordering, confirm the 40 mm stroke, PT1/4 port, built-in magnet (S), and the male M18x1.5 rod thread (B).
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, with a speed of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake. The -S code indicates a built-in magnet for use with AirTAC reed or electronic switches in the body grooves. The -B code specifies the male M18x1.5 piston rod thread.
