1. Introduction
Used in pressure shear test for rubber bearing of roads, bridges and buildings.
Used for plate rubber bearings, pot type rubber bearings, spherical bearings, common rubber bearings, special-shaped rubber bearings, etc.
It can automatically complete limit compression strength, compression elastic modulus, shear elastic modulus, shear adhesive property, shear aging test.
