The product is mainly used in highway bridges, railway bridges, urban overpass. The main function is transferring the reaction force of upper part reliably to the pier, and also can complete the horizontal displacement of beam structure due to the brake temperature, coagulation shrinkage of concrete and loading effect.

This product takes high elasticity rubber layers as main material, inlaid and adhesive with a thin steel , then cured into final product. The products have enough vertical stiffness to withstand vertical load, can transfer the pressure of upper structure to the pier, good flexibility to adapt to the beam end rotation, large shear deformation to meet the upper structure horizontal displacement. Rubber with its unique function, fundamentally improve the performance of bridge bearings.

The friction coefficient between PTFE plate and stainless steel plate (add grease): < 0。03, grade of the load 100kN to 15000KN。
