The AirTAC AirTAC SDA63X100SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 100mm 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 SDA63X100SB is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Built with a short riveted body that integrates the barrel, rear cover, piston, and rod, it drastically reduces axial mounting depth compared to conventional round-body units. This space-saving footprint makes it highly effective for machinery where overall length is restricted. The hard-anodized bore and two-way piston seal ensure durable, leak-free operation.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, enabling precise end-of-stroke detection. It also features a male-thread piston rod (-B) sized at M18x1.5 for secure mechanical load coupling. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, and operates efficiently at speeds between 30 and 500 mm/s.

Provides robust clamping force for machining center pallets, utilizing the 100 mm stroke to clear the work area during automated part loading and unloading.
Actuates lower-tier metal strip feed guides in progressive stamping lines, where the short body length prevents interference with adjacent press tooling.
Drives the folding mechanism for large corrugated carton erecting machines, easily handling the resistance of thick cardboard via the male M18x1.5 rod connection.
Selecting this 63 mm bore model provides a safe working load of roughly 935 N (about 60% of its 1558.6 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 79.4 kg with a 2:1 safety margin. If your application requires less force, the SDA50 offers 981.7 N at 0.5 MPa; conversely, stepping up to the SDA80 yields 2513.3 N. Keep in mind that a plain compact cylinder does not hold its position when air pressure is lost or the valve is centered—the piston will drift, as the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. For suspended loads, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 100 mm stroke, PT1/4 port, built-in magnet, and male M18x1.5 rod thread.
Quick checklist
At 0.5 MPa, this 63 mm bore cylinder provides 1558.6 N of push force and 1401.5 N of pull force. 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.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is not an adjustable air cushion. For high kinetic energy or rapid cycling, you should add an external shock absorber or reduce the approach speed.
