G223 Spherical Seat Compression PlatenG223 Spherical Seat Compression PlatenG223 Spherical Seat Compression Platen

Spherical seat platens are for applications that require platen self-alignment. These platens ensure that loading is concentrically and evenly applied to specimens that do not stand perpendicular to the platen surface. They are commonly used when test samples are cut in a non parallel manner between the sample top surface and it’s bottom surface. Once arranged, the user can fix the spherical setup by tightening four bolts. It’s simple.

The G223 spherically seated compression platens have a standard and a large angle version that accommodates angular displacement up to +/- 15 degrees of the top of the specimen with reference to the machine’s loading axis. These spherical seated compression platens are typically mounted to your test machine crosshead and normally used with a fixed version (also known as plane version) compression platen that is mounted to the base of the machine.
