UNIVERSAL SPHERICAL TENSION ADAPTER (USTA)

1

2

The USTA is a versatile device that connects a wide number of tension accessories to an Instron test machine, provides a smooth spherical seat, and requires few or no additional adapters. The USTA threads into a standard machine interface from the direction of the test space, connects to the machine thread on one end and directly to the accessory on the other, all in one compact device. The USTA consists of a sleeve component that is threaded for the test machine and a shank component that is threaded for tension accessories. The two components mate on matching spherical surfaces that allow flexibility during alignment and sustain the load during a test. A nut holds the assembly together and a polymer washer allows flexibility without looseness. UNIVERSAL SPHERICAL TENSION ADAPTERS Catalog Number
