The AirTAC AirTAC SDA50X80H Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 80mm 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 SDA50X80H is a double-acting, single-rod compact cylinder engineered for tight axial mounting spaces. A riveted unibody design integrates the barrel, rear cover, and piston to drastically reduce overall depth compared to conventional round-body units. Delivering 981.7 N of push force at 0.5 MPa, this 50 mm bore model is built for rigorous pneumatic duties.
This specific SKU features an 80 mm stroke and utilizes a high-temperature fluororubber (FKM) seal for enhanced oil resistance. The bore is hard-anodized, and end-stops rely on a fixed NBR bumper rather than an adjustable air cushion. Note that this configuration lacks a piston magnet, so it cannot host magnetic position switches without upgrading to an -S variant.

Secures heavy aluminum castings onto machining centers. The 981.7 N push force at 0.5 MPa ensures rigid workholding, while the compact riveted body fits within multi-station tombstone grids.
Actuates the release gate in automated palletizer magazines. The 80 mm stroke provides the exact travel needed to index empty pallets, and the FKM seals withstand elevated ambient temperatures near heat-shrink tunnels.
Raises lowerator transfer arms in conveyor systems. The 20 mm piston rod handles the 50 kg vertical lift with a 2:1 safety margin, though an external check valve is required to prevent drifting if compressed air drops.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. The current 50 mm bore offers a safe working load of roughly 589 N (about 60% of its 981.7 N capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin.
Confirm your ordering essentials: 50 mm bore, 80 mm stroke, PT1/4 port, female M10x1.5 rod thread, and FKM seals. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end, so install an external rod lock or pilot-operated check valve if the application demands strict load holding.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, push increases to 1374.4 N and pull to 1154.5 N. The theoretical maximum push force is 200 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No. This model uses a fixed NBR bumper at each end to decelerate the stroke end; it is not an adjustable air cushion, so you should slow the approach or add external shock absorbers for high-energy loads. Additionally, this SKU lacks a piston magnet and cannot support reed or electronic switches unless upgraded to an -S variant.
