The AirTAC AirTAC SDA63X85BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 85mm 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 SDA63X85BH is a double-acting, single-rod compact cylinder engineered with a 63 mm bore and an 85 mm stroke. A riveted assembly joins the barrel, rear cover, piston, and rod, yielding an extremely short axial footprint to conserve machine space where conventional round bodies fail to fit. It delivers a robust 1558.6 N push and 1401.5 N pull at 0.5 MPa, operating at speeds from 30-500 mm/s.
This specific configuration includes a male M18x1.5 piston rod thread for secure mechanical load coupling, paired with PT1/4 air ports. The -H designation indicates fluororubber (FKM) seals for enhanced thermal and oil resistance, while fixed NBR bumpers manage end-stop deceleration. Because this SKU lacks the -S magnet, it cannot host magnetic reed or electronic switches.

Secures heavy cast iron engine blocks during machining operations, utilizing the 1558.6 N extend force to prevent workpiece shifting under high spindle torque.
Stages corrugated cartons onto wooden pallets within tight conveyor frames, where the short riveted body avoids encroaching on adjacent packaging lanes.
Ejects formed sheet metal brackets from stamping dies, relying on the male M18x1.5 rod end to thread securely into the ejector plate.
When sizing this unit, consider stepping down to the SDA50, which provides 981.7 N of push force at 0.5 MPa, or moving up to the SDA80, which yields 2513.3 N at the same pressure. For the SDA63X85BH, the computed safe working load is approximately 935 N (about 60% of the 1558.6 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Ensure your ordering essentials match the 63 mm bore, 85 mm stroke, PT1/4 ports, male M18x1.5 rod end, and FKM seals. Remember that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only slows the piston near stroke end and does not function as a locking brake. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. The theoretical maximum push force is 318 kgf at the 1.0 MPa operating pressure limit.
No. This SKU lacks the -S piston magnet, so it cannot accept reed or electronic switches. Additionally, it uses fixed NBR bumpers for end-stop deceleration rather than adjustable air cushions; for high kinetic energy loads, add an external shock absorber.
