The AirTAC AirTAC SDA63X10S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 10mm 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 SDA63X10S is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa within a minimal axial envelope. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, making it highly effective for machinery where space savings are critical. The 63 mm bore houses a hard-anodized inner wall and a two-way piston seal for reliable operation.
Equipped with a built-in piston magnet (-S), this unit is fully compatible with AirTAC magnetic reed or electronic switches fitted into the body grooves. The 10 mm stroke is governed by a fixed NBR bumper at each end to decelerate the end stop; because this is not an adjustable air cushion, high-energy cycles may require slowing the approach or adding an external shock absorber. The PT1/4 port and 20 mm rod ensure robust pneumatic and mechanical coupling for heavy-duty tasks.

Provides a short 10 mm ejection stroke inside tight mold platens, utilizing the 1558.6 N push force to knock finished plastic parts safely out of the cavity.
Acts as a compact back-gauge stop in metal forming machinery where axial depth is restricted, ensuring precise sheet metal positioning before bending.
Drives a short vertical lift mechanism in conveyor transfer systems, moving loads up to 79.4 kg with a 2:1 safety margin before downstream packaging.
Selecting this 63 mm bore model provides a safe working load of roughly 935 N (about 60% of the 1558.6 N push at 0.5 MPa), which translates to a vertical lift capacity of approximately 79.4 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA50 offers 981.7 N at 0.5 MPa, while upgrading to the SDA80 yields 2513.3 N for heavier demands. Remember that a plain compact cylinder drifts when air is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end rather than locking the load; for position holding, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 63 mm bore, 10 mm stroke, PT1/4 port, female rod-end thread, and the required -S magnet for switch sensing.
Quick checklist
This double-acting cylinder generates a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N. The theoretical maximum push is 318 kgf at the 1.0 MPa operating pressure limit.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the rod near the end of the stroke and does not act as a lock or brake. To maintain position, you must integrate an external rod lock or a pilot-operated check valve.
