Raagen Swivels for Actuator Systems

Confidently meet the demands of closed-loop servohydraulic testing with Raagen Swivels. Available with or without backlash adjustment, these fatigue-rated swivels are precision engineered to deliver the strength, durability and versatility required for optimal performance in a variety of structural testing applications. These swivels provide unmatched quality and easy integration with Raagen actuator assemblies, seismic systems and simulation tables. To minimize weight and maximize strength, the swivels are cast with fatigueresistant ductile iron. Maintenance-free, non-metallic bearings reduce friction, eliminate the need for lubrication and increase swivel life span.

With our unique combination of testing knowledge and engineering expertise, Raagen develops swivels that are optimized to deliver flawless performance and high reliability over years of heavy use. We scrutinize every detail of the design, materials and manufacturing. Raagen Swivels can be used for the majority of structural testing applications that require swivel rotation with minimum backlash. Of course, one way to eliminate backlash is to run loading schemes that do not reverse the load. For applications where loading cycles stay in tension or in compression, or loads are applied statically or pseudodynamically, Raagen Swivels are the right choice.
