The AirTAC AirTAC SDA63X25BH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 25mm 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 SDA63X25BH is a double-acting single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, and piston into an ultra-short profile, significantly reducing axial mounting depth compared to conventional round-body units. This specific configuration includes a male M18x1.5 piston rod thread for robust mechanical coupling and an FKM fluororubber seal option for enhanced thermal and oil resistance.
The 63 mm bore features a hard-anodized inner wall and a PT1/4 port. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should reduce approach speed or add external shock absorbers for high-energy loads. Because this SKU lacks the -S magnet suffix, it cannot host reed or electronic switches; position sensing requires the -S variant instead.

Drives heavy plating racks into chemical baths where the compact 63 mm body saves axial space and the FKM seal withstands elevated ambient temperatures and oil mists.
Pushes stamped metal blanks out of press dies using the 1558.6 N extend force, leveraging the male M18x1.5 rod for secure tooling attachment.
Raises lowerator forks in packaging lines; the fixed NBR bumper absorbs the 25 mm stroke impact, though vertical loads need a pilot-operated check valve to prevent drifting.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. The SDA63X25BH provides a calculated safe working load of roughly 935 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 25 mm stroke, PT1/4 port, male M18x1.5 rod, and FKM seals. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end and acts as neither a lock nor a brake. To suspend a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 1558.6 N and the pull force is 1401.5 N. At 0.7 MPa, push is 2182.1 N and pull is 1962.2 N. The theoretical maximum push force is 318 kgf at 1.0 MPa, which is the maximum operating pressure. The cylinder operates at speeds of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot host reed or electronic switches. You must select the -S variant to enable sensing. Additionally, it uses a fixed NBR bumper for end-stop deceleration rather than an adjustable air cushion, so external shock absorbers are recommended for high-speed operations.
