YJW-5000~30000 Microcomputer controlled electro-hydraulic servo compression and shear testing machine
Introduction
YJW SERIES Elastomeric Bearing Testing Machine are mainly used for the mechanical properties, damping performance, large deformation test and detection of rubber bearings of highways, railways, bridges, building plate rubber bearings, basin bearings, and spherical bearings. It can carry out compressive elastic modulus test, shear elastic modulus test, shear test (static shear), ultimate compressive strength test, friction coefficient test, corner test and load test of highway bridge basin bearing. Detection of compression deformation and radial deformation.
