The AirTAC SDA63X40BH 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 SDA63X40BH is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth, providing a minimal footprint where a conventional round-body unit would be too long. This specific SKU is configured with a male M18x1.5 piston rod end for robust mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The bore features a hard-anodized inner wall paired with a two-way piston seal, operating at speeds from 30-500 mm/s. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end to decelerate the stroke. Because this configuration omits the -S magnet code, it cannot directly host AirTAC reed or electronic switches; position sensing requires external methods or the -S variant.

Provides the robust 1558.6 N extension force needed to eject dense plastic automotive interior panels from heavy tooling, with the male M18x1.5 rod securely threading into the ejector plate.
Actuates a heavy-duty routing gate on a packaging line, utilizing the 40 mm stroke to push loaded pallets onto a secondary track while the FKM seals withstand elevated ambient temperatures.
Locks aluminum engine blocks in place during high-speed machining operations, where the compact riveted body minimizes interference with the cutting tool paths.
When sizing this 63 mm bore actuator, evaluate your force margins carefully. Stepping down, the SDA50 provides 981.7 N of push at 0.5 MPa, whereas stepping up to the SDA80 yields 2513.3 N. Remember that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered—the fixed bumper only decelerates near the stroke end, so an external rod lock or pilot-operated check valve is required for secure holding.
Confirm your ordering essentials before checkout: this SDA63X40BH specifies a 63 mm bore, 40 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals. It is built without a piston magnet, so it will not support magnetic sensing without switching to an -S designated model.
Quick checklist
This double-acting cylinder generates 1558.6 N of push and 1401.5 N of 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 is 318 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports speeds of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option to enable magnetic sensing. Additionally, end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
