The AirTAC AirTAC SDA16X50B Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 50mm 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 SDA16X50B is a double-acting, single-rod compact cylinder engineered to deliver 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly abbreviated unit, drastically reducing axial mounting depth compared to conventional round-body designs. This space efficiency is critical when fitting mechanisms into tight machine footprints.
This specific configuration includes the B option, providing a male M5x0.8 threaded piston rod for straightforward load coupling, rather than the default female M3x0.5 thread. The 16 mm bore features a hard-anodized inner wall and utilizes a fixed NBR bumper at each end to decelerate the stroke. Since this SKU lacks the S magnet option, it cannot directly mount AirTAC magnetic switches.

Uses the male M5x0.8 rod to push separated circuit boards from a routing fixture, capitalizing on the 50 mm stroke and 100.5 N force within a shallow electronics assembly chassis.
Executes short 50 mm tucking strokes on pharmaceutical packaging lines where the abbreviated riveted body avoids clashing with adjacent sealing jaws.
Drives a 5.1 kg vertical fluid valve in automated dosing equipment, relying on the hard-anodized 16 mm bore for smooth, low-friction cycling at up to 500 mm/s.
When sizing this actuator, evaluate your force margins both ways: stepping down to the SDA12 yields 56.5 N of push at 0.5 MPa, while stepping up to the SDA20 provides 157.1 N. The SDA16X50B offers a safe working load of roughly 60 N (about 60% of its 100.5 N capacity at 0.5 MPa) and can vertically lift approximately 5.1 kg with a 2:1 safety margin. Operating speeds span 30-500 mm/s, operating pressure is 0.15-1.0 MPa, and the port size is M5x0.8.
Remember that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than acting as a lock. For suspended loads, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 16 mm bore, 50 mm stroke, male M5x0.8 rod thread, M5x0.8 port, and the absence of a sensor magnet.
Quick checklist
At 0.5 MPa, this 16 mm bore cylinder provides 100.5 N of push force and 86.4 N of pull force. At 0.7 MPa, push increases to 140.7 N and pull to 121 N. The theoretical maximum push is 21 kgf at the 1.0 MPa operating pressure limit.
No adjustable air cushion exists; a fixed NBR bumper absorbs the end stop, so you should slow the approach or add an external shock absorber for high-energy cycles. Additionally, because this SKU lacks the S magnet option, it cannot support reed or electronic switches.
