The AirTAC AirTAC SDA63X50B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 50mm 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 SDA63X50B is a double-acting single-rod compact cylinder engineered to deliver 1558.6 N of push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod to minimize axial length, saving valuable machine footprint where a conventional round-body unit would not fit. The bore is hard-anodized and uses a two-way piston seal for reliable operation.
This specific SKU features a male M18x1.5 threaded piston rod for robust load coupling. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent wear. Because this configuration lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Drives stripper plates out of injection molding machines where short axial depth is critical, utilizing the 1558.6 N extend force to safely eject heavy plastic parts.
Pushes loaded pallets sideways on a packaging line, using the male M18x1.5 rod end to securely attach a wear-resistant contact blade.
Secures lower die shoes into stamping presses, providing the necessary holding push to lock heavy tooling in place before the ram descends.
When sizing this unit, compare its 1558.6 N push at 0.5 MPa against adjacent bores: stepping down to the SDA50 yields 981.7 N, while stepping up to the SDA80 provides 2513.3 N. A practical safe working load is roughly 935 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 79.4 kg with a 2:1 safety margin.
To finalize your order, confirm the 63 mm bore, 50 mm stroke, PT1/4 port, and the male M18x1.5 rod thread. Note that a standard cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end without locking the piston; holding a suspended load requires an external rod lock or pilot-operated check valve.
Quick checklist
At 0.5 MPa this cylinder pushes with 1558.6 N and pulls with 1401.5 N. 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 adjustable air cushion exists; end-stopping is handled by a fixed NBR bumper. For high speeds, add an external shock absorber. Additionally, this SKU lacks the -S magnet, so it cannot accept reed or electronic switches.
