The AirTAC AirTAC SDA16X35S Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 35mm 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 SDA16X35S is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit achieves a remarkably short axial length. It delivers a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa, operating efficiently within a 30-500 mm/s speed range.
Equipped with a built-in piston magnet (-S), this model interfaces directly with AirTAC reed or electronic switches housed in the body grooves. The 6 mm piston rod features an M3x0.5 female thread, and end-stops rely on a fixed NBR bumper rather than an adjustable cushion. This bumper decelerates the stroke end but is not a locking mechanism; a pilot-operated check valve is required to hold loads if air pressure drops.

Actuates the cutting tool guide on an electronics assembly line, utilizing the 35 mm stroke and 100.5 N force to precisely separate printed circuit boards without stressing components.
Closes the heat sealing head on small medical blister packaging equipment, where the compact riveted body minimizes axial depth and the integrated magnet confirms cycle completion.
Drives a micro-dispense nozzle for reagent application, relying on the 6 mm rod and fixed NBR bumper to absorb the 35 mm stroke end impact without bouncing the fluid volume.
When sizing this 16 mm bore, evaluate your neighbors: the SDA12 offers 56.5 N push at 0.5 MPa for lighter duties, while the SDA20 steps up to 157.1 N for heavier cycles. The 100.5 N output at 0.5 MPa yields a safe working load around 60 N (roughly 60% capacity) and a vertical lift capability of about 5.1 kg with a 2:1 safety margin. To finalize your order, confirm the 35 mm stroke, M5x0.8 port, required magnet (included here), and whether the standard female rod end suits your mounting interface.
Quick checklist
This 16 mm bore double-acting cylinder provides a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, push increases to 140.7 N. The theoretical maximum push is 21 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a temperature range of -20 to +70 C.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. If your cycle runs at high speed, add an external shock absorber. Furthermore, the bumper is not a brake; the piston will drift if air is lost, so an external rod lock is needed to hold a vertical load safely.
