Series 249 and 249N Swivels
Fatigue-resistant ductile iron minimizes weight and maximizes strength, and maintenance-free non-metallic bearings reduce friction, eliminate the need for lubrication and increase lifespan. MTS swivels integrate seamlessly with MTS actuator assemblies, seismic systems and simulation tables.
Key Product Features
