1.Classification according to the structure from it is divided into
A. Ordinary laminated rubber bearing is divided into rectangular laminated rubber bearing (code GJZ) and circular laminated rubber bearing (code GYZ)
B. Teflon slide type rubber bearing is divided into rectangular Teflon slide type rubber bearing (code GJZF4) and circular Teflon slide type rubber bearing (code GYZF4).
2.Classification according to the bearing material and the application temperature it is grouped into
A.Normal temperature rubber bearing should be produced by nitrogen butyl rubber(CR), the suitable temperature is -25℃- 60℃, shall not substitute natural rubber for chloride butyl rubber, also does not allow to blend natural rubber in chloride butyl rubber;
B. Cold-resistance rubber bearing should be producted by natural rubber(NR), the suitable temperature is -40℃- 60℃.

Application
Ordinary plate type rubber bearingis widly used for ordinary bridge and road. The teflon rubber bearing is used for 30-meter long span bridge, the simple beam continuous slab bridge and the multi-span continuous girder bridge can be used for movable support; Continuous beam jacking, t-beam transverse shift and large equipment slip can be used for sliding block.
