Characteristics

The Rainbow Laminated Elastomeric Bearing is a reinforced bearing manufactured from synthetic and Natural Rubber.Its load bearing characteristics, resistance to fatigue, high strength and ability to withstand loads for long periods without failure are exceptional.

 

Features

 

Rainbow Laminated Elastomeric Bearings consist of vulcanized elastomeric blocks, reinforced by two or more steel sheets. The vulcanized reinforcing layers of high-strength steel sheeting are fully enclosed in elastomer to ensure absolute corrosion protection and complete freedom from maintenance

The Rainbow formulated elastomer is extremely resistant to ageing and weathering influences such as ozone and UV radiation.

 

Application

 

Rainbow Laminated Elastomeric Bearings are used mainly in Bridges and Buildings.

 

They provide load bearing capacity capable of providing translational movement in both horizontal axes together with rotational capacity.

 

Rainbow Laminated Elastomeric Bearings are manufactured in layers. They consist of alternate layers of Natural Rubber and steel Plates. The entire bearing is then encapsulated within an outer layer of Natural Rubber thereby making the bearing resistant to Corrosion and weathering.

 

Principles of Operation

 

The Rainbow Laminated Bearing is used in bridge construction throughout the world. It allows movement of a bridge deck on its supporting structure when changes in the deck length, and also width occur with changing temperature.

 

Vertical Loads from the structure, live traffic loads and wind forces are transferred to and absorbed efficiently by the bearing.

 

These bearings have a low horizontal stiffness, so that only minor forces are imposed on the supports, but a high vertical stiffness to prevent appreciable changes in height under changing load.

 

Some end rotation of the deck can also be accommodated by the bearings without greatly affecting the pressure distribution on supporting piers.

 

The rubber and steel within the bearing are vulcanized during manufacture to ensure complete adhesion between all surfaces and making the bearing resistant to shear and pressure.

 

Standards and Testing

 

Rainbow Bearings can be manufactured to the following standards i.e. BS 5400, EN 1337 and AASHTO M 251 LRFD Sec. 14.

 

Rainbow maintain strict Quality controls to ensure total compliance with respective Standard.

 

Rainbow always perform random bearing test in PCSIR laboratory for best performance and quality.

 

Quality

 

Rainbow Bearings have been used successfully around the world for the last 42 years under harsh and demanding conditions. Till date our products are fully operational to our clients’ complete satisfaction.

 

Qualified personnel, established and tested manufacturing process together with Rainbow’s superior Materials Technology ensure that the quality of Rainbow products is always maintained.

 

All Rainbow products are fully warranted.

 

Range of Product

 

Rainbow offers the complete International range of sizes of Bridge Rubber Bearings. The usual load range lies between 100 kN and 9000 kN  (Serviceability Limit state)

 

Rainbow Bearings are available in square, rectangular and circular shape.

 

Rainbow has the ability to design, manufacture and supply Bearings customized to special design requirements.

 

In addition to Rainbow standard elastomeric bearings, special bearings for Vibration Isolation, Seismic Isolation and Damping can be designed, manufactured and supplied.
