The AirTAC AirTAC SDA63X150B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 150mm 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 SDA63X150B is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to conventional round-body units, providing a highly space-efficient footprint for tight machine layouts. This specific SKU features a male M18x1.5 piston rod thread for robust load coupling.
Because the 150 mm stroke exceeds the 130 mm maximum standard stroke for this 63 mm bore, this unit is a non-standard, made-to-order configuration. The bore is hard-anodized for longevity, and deceleration at the end caps relies on a fixed NBR bumper rather than a field-adjustable air cushion. Note that this SKU lacks a piston magnet and therefore cannot support position sensing without upgrading to the -S variant.

Pushes heavy pallets onto a secondary packaging line using the 1558.6 N extend force, while the short riveted body minimizes interference with adjacent conveyor frames.
Raises a 79 kg material lift gate through a 150 mm vertical stroke, requiring an external pilot-operated check valve to prevent drifting when the air supply is cut.
Drives an ejection plate inside a plastics molding cell via the male M18x1.5 rod end, relying on the fixed NBR bumper to absorb the impact at the end of the retract stroke.
When sizing your actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80, which 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 compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load; holding a suspended mass requires an external rod lock or pilot-operated check valve. Confirm your ordering essentials: 63 mm bore, 150 mm non-standard stroke, PT1/4 port, no magnet, and the male M18x1.5 rod thread.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull 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, handles a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C at speeds of 30-500 mm/s.
No, this specific SKU does not include the -S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. If your application requires position sensing, you must select the SDA63X150BS variant. Additionally, because this is a 150 mm stroke on a 63 mm bore, it exceeds the 130 mm standard maximum and is manufactured as a non-standard, made-to-order part.
