Rotomation A190TCS37185 Rotary Actuator Assembly

Rotomation's A190TCS37185 Rotary Actuator Assembly, sold as A1-90-TC-S37-1/8-5, is a 90-degree pneumatic rotary actuator with an upper-manifold configuration in Rotomation's A1 family, weighing about 0.81 lb and listed as discontinued by the manufacturer. The A1-90 configuration specifies a 90-degree rotation and is built on a 5/8-inch bore, with Rotomation noting that the platform can be configured in nearly two billion standard variations and typically ships within a few days when stocked. Rotomation's design uses a rack-and-pinion arrangement to convert linear actuation into rotary output, and the upper-manifold variant keeps plumbing connections on the top; the product line is used in metalworking, assembly, testing, and packaging applications.
