The AirTAC AirTAC SDA20X100H Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 100mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA20X100H is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial depth, fitting where round bodies cannot. At 0.5 MPa, it generates 157.1 N of push force and 131.9 N of pull force. This specific SKU includes an H-designated fluororubber (FKM) seal for enhanced thermal and oil resistance.
This unit features an 8 mm piston rod and an M5x0.8 port. It lacks a piston magnet, so it cannot host reed or electronic switches without specifying the S option. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke limits; it is not an adjustable air cushion, so external shock absorbers are advised for high-energy 100 mm strokes.

Provides 157.1 N of push to drive the cutting head along a 100 mm axis, with the FKM seal resisting flux vapors and ambient heat near soldering stations.
Extends a full 100 mm to actuate a routing flap on a packaging line, where the compact body saves valuable space inside the conveyor frame.
Actuates a precision fluid valve for chemical dosing, leveraging the fluororubber seal to maintain integrity against aggressive solvents.
For sizing context, stepping down to the SDA16 yields 100.5 N push, while moving up to the SDA25 provides 245.4 N at 0.5 MPa. Based on the 157.1 N figure, the safe working load is approximately 94 N (60% capacity), translating to a vertical lift of roughly 8 kg with a 2:1 safety margin. When ordering, confirm the 20 mm bore, 100 mm stroke, M5x0.8 port, female M4x0.7 rod thread, and the FKM seal. Remember that this cylinder will drift and lose its position if air pressure drops; use a pilot-operated check valve or external rod lock to suspend loads securely.
Quick checklist
At 0.5 MPa, the push force is 157.1 N and the pull force is 131.9 N. At 0.7 MPa, push is 219.9 N. The theoretical maximum push is 32 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU does not have a piston magnet, so it cannot trigger reed or electronic switches. You must select the S option (e.g., SDA20X100HS) to enable sensing capabilities.
