Laminated Rubber Bearing Pad for Railway Bridge

Bearing Pads
We are one of the leading Manufactures &suppliers for Elastomeric Bridge bearing pads in China,our product range includes awide range of bearing pads, bridge bearing pads, elastomeric bridge bearing pads and neoprene bridge bearing pads.
Types of bearing pads1.Classification according to the structure from it is divided into:
a. Plain bearing (Non-reinforced elastomeric bearing)Plain bearing pads consist of only elastomer.b. Laminated elastomeric bearing padLaminated bearing consist of elastomer and alternate layers of steel reinforcement bonded together.c. Ptfe Elastomeric bearing pad -freely slidingAdhere alayer of 1.5mm to 3mm thick polytetrafluoroethylene plate on the surface.
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.TechnologyItemIndexultimate compression strength Ru/Mpa≥70measured elasticity modulus of compression E1 /MpaE±Ex20%measured elasticity modulus of shear G1 /MpaG±Gx15%measured elasticity modulus of shear after aging G2 /MpaG1±G1x15%measured tan valve of corner tanδ of concrete bridge≥1/300measured tan valve of corner tanδ of steel bridge≥1/500measured surface friction of ptfe plate and steel plate μf (adding silicion grease)≤0.03
