The Process

The UNASIS Portable Proof Load Kit is the most popular method of proof load testing. The tool is utilised to cut the v-groove of a bearing, sleeve, or chamfered housing. The tool is easy to use, adaptable, reliable, and completely portable. A single kit can be modified through the use of a vast range of bearings by utilising the adapter kits. This includes an electronic load cell with TEDS memory, handheld load display and a DTI gauge all calibrated to required specifications.
