The AirTAC AirTAC SDA63X15S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 15mm 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 SDA63X15S 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, piston, and rod into an exceptionally short axial footprint, conserving valuable machine depth where conventional round bodies cannot fit. A hard-anodized bore minimizes friction, while the integrated -S piston magnet enables position detection via AirTAC reed or electronic switches.
This 63 mm bore unit features a 20 mm rod and a PT1/4 port. End-of-travel deceleration is managed by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. With a 15 mm stroke, it provides rapid, short linear motion within a highly durable aluminum frame.

Provides robust 1558.6 N push force to eject dense plastic parts from injection molding dies, utilizing the short 15 mm stroke for rapid cycling.
Secures heavy cast iron blocks during CNC machining operations, where the built-in magnet verifies clamp engagement before cutting begins.
Acts as a high-force mechanical stop in automated pallet lifts, handling dynamic loads safely within a minimal axial envelope.
When sizing this model, evaluate your force requirements carefully. Stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, whereas stepping up to the SDA80 provides 2513.3 N. The SDA63X15S offers a computed safe working load of roughly 935 N (about 60% of its 1558.6 N capacity) and can vertically lift approximately 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 63 mm bore, 15 mm stroke, PT1/4 port, female rod-end thread, and the required -S magnet.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The fixed NBR bumper only reduces impact velocity near the stroke end; it does not function as a locking brake. If your application must hold a vertical load without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting 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. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports speeds from 30 to 500 mm/s.
No, the piston will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumper at each end only decelerates the piston near the stroke extremes; it is not an adjustable air cushion or a mechanical brake. To maintain position, you must add an external rod lock or a pilot-operated check valve.
