The AirTAC AirTAC SDA63X70B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 70mm 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 SDA63X70B is a double-acting single-rod compact cylinder engineered to deliver 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly space-efficient unit, drastically reducing axial mounting depth compared to conventional round-body designs. The 63 mm bore operates on PT1/4 ports and features a hard-anodized inner wall paired with a two-way piston seal for prolonged service life.
This specific SKU includes the B option, providing a male M18x1.5 threaded piston rod end for robust mechanical coupling to your load. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage. Note that this configuration lacks the S magnet option, so it cannot support AirTAC reed or electronic switches.

Secures machining pallets inside automated workholding zones where the short riveted body conserves valuable Z-axis clearance, applying 1558.6 N of clamping force at 0.5 MPa.
Raises heavy cardboard bundles between conveyor tiers using the male M18x1.5 rod end, safely managing vertical lifts up to 79.4 kg with a 2:1 safety margin.
Drives secondary ejection arms on plastic molding lines, relying on the hard-anodized 63 mm bore to withstand repetitive cycling at speeds between 30 and 500 mm/s.
When sizing this actuator, evaluate your neighbours: 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 at the same pressure. For the SDA63X70B, the 1558.6 N output at 0.5 MPa translates to a safe working load of roughly 935 N (operating at a 60% derating) or a vertical lift capacity of about 79.4 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact configuration: 63 mm bore, 70 mm stroke, PT1/4 port, male M18x1.5 rod thread, and no sensor magnet. Keep in mind that a standard compact cylinder does not hold its position upon air loss; the piston will drift, and the fixed bumper only decelerates it near the stroke end rather than locking the load. If your application requires static holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
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 is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa and a temperature range of -20 to +70 C.
No. This SKU uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion; high-speed applications may need external shock absorbers. Additionally, it lacks the S magnet option, so it cannot accept AirTAC reed or electronic switches. It does feature the B option, giving the 20 mm rod a male M18x1.5 thread.
