The AirTAC SDA63X20H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 20mm 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 SDA63X20H is a double-acting single-rod compact cylinder engineered with a 63 mm bore and a 20 mm stroke. The short riveted body integrates the barrel, rear cover, piston and rod to minimize axial mounting depth, saving valuable machine footprint where a traditional round-body unit would not fit. This specific H-seal variant utilizes fluororubber (FKM) components for enhanced thermal and oil resistance, operating within the standard -20 to +70 C range.
Delivering a robust 1558.6 N push and 1401.5 N pull at 0.5 MPa, this model handles substantial workloads. The bore dictates a 20 mm piston rod, PT1/4 air ports, and an M10x1.5 female rod-end thread for secure load coupling. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Note that this SKU lacks a piston magnet, so position sensing is not supported without the -S option.

Drives short-stroke ejection pins inside tight mold platen recesses, utilizing the FKM seals to withstand residual heat and synthetic hydraulic fluid exposure.
Positions heavy metal blanks accurately before the press cycle, relying on the 1558.6 N extend force to push thick gauge material into the tooling nest.
Raises loaded pallets over a brief 20 mm vertical gap within dense conveyor junctions where minimizing the actuator's axial length prevents frame interference.
When sizing this 63 mm bore actuator, compare its 1558.6 N push at 0.5 MPa against adjacent bores: the SDA50 provides 981.7 N, while the SDA80 offers 2513.3 N. To finalize your order, confirm the 63 mm bore, 20 mm stroke, PT1/4 port, female rod thread, and the FKM seal requirement. Because a standard compact cylinder drifts when air pressure is lost or the valve centers, applications requiring suspended load holding must incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and travels at speeds of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion; for high kinetic energy applications you should add an external shock absorber. Additionally, this SKU lacks a piston magnet, so it cannot support reed or electronic switches unless you specify the -S variant.
