1.Classification according to the structure from it is divided into: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 -25ºC- 60ºC, shall not substitute natural rubber for chloride butyl rubber, also does not allow to blend natural rubber in chloride butyl rubber;
a. Cold-resistance rubber bearing should be producted by natural rubber(NR), the suitable temperature is -40ºC- 60ºC.
Shape:
Bearings can be molded in rectangular, square, circular or other shapes. Note that custom shapes, clipped corners, slotted, skewed and tapered bearings may carry cost premiums due to mold modifications.
