The AirTAC SDA50X45BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 45mm 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 SDA50X45BH is a double-acting compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its short riveted body minimizes axial mounting depth, providing a distinct footprint advantage in tight machinery layouts where longer profile cylinders cannot fit. The unit operates at speeds between 30-500 mm/s.
This specific configuration includes a male M18x1.5 threaded piston rod for robust load coupling and utilizes a fluororubber (FKM) seal for enhanced thermal and oil resistance. End-stopping is handled by a fixed NBR bumper that decelerates the piston near stroke limits; it is not an adjustable air cushion, so high-energy cycles may require external shock absorption.

Secures heavy cast iron engine blocks during machining operations, utilizing the 981.7 N extend force to maintain rigid positioning against cutting forces.
Indexes empty wooden pallets into a high-speed filling line, where the compact 45 mm stroke and short body length conserve floor space within the conveyor framework.
When sizing this unit, 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, allowing you to scale thrust precisely. To order, confirm the 50 mm bore, 45 mm stroke, PT1/4 port, male M18x1.5 rod thread, FKM seals, and the absence of a piston magnet. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; if your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push force is 200 kgf at the maximum operating pressure of 1.0 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake. Because this SKU lacks the -S magnet option, it cannot support reed or electronic switches; position sensing requires the -S variant.
