　　The basin rubber bearing has the advantages of light weight, compact structure, simple structure, low building height, convenient processing and manufacturing, saving steel and reducing cost. It is an ideal support suitable for the use of big break bridges. There are three commonly used categories: GPZ, GPZ (II) and GPZ (KZ). The bearing capacity of GPZ (II) series is 31 grades at present and the bearing capacity is 0.8MN-60MN, which can meet the needs of large bridge construction. In the GPZ (II) standard series, the horizontal bearing capacity of the fixed bearing in the direction of non slip in all directions and unidirectional bearings is not less than 10% of the bearing capacity of the bearing. The horizontal bearing capacity of the aseismic support is not less than 20% of the support bearing capacity. Bearing rotation angle is not less than 0.02rad. 5201 grease lubrication, normal temperature type movable bearing design minimum friction coefficient 0.03.; add 5201 grease lubrication, cold type movable bearing design friction coefficient minimum 0.06.
