Rubber Bearings

A rubber bearing is defined as a device which permits constrained relative motion between two parts: rotation or linear movement. The fundamental purpose of a bearing is to reduce friction and wear between rotating parts which come in contact with one another in any kind of mechanism. Bearings are classified broadly into categories according to the motions they allow and according to their principle of operation.

Each type of bearing is used for different purposes. Bearings are made of various materials but rubber is a widely demanded material for making bearings. Rubber has proved to be an excellent bearing material, especially under circumstances in which abrasives may be present in the lubricant. The rubber used to make bearings is a tough resilient compound similar in texture to that in an automobile tyre.

The highlight of the rubber bearings is that they tend to work on the principle of base isolation and limits the energy transferred from the ground to the structure in the event of an earthquake. Base Isolation Lead Rubber Bearings is the special type of bearing that consists of a laminated rubber and steel bearing with steel flange plates for mounting to the structure.

Since all isolators carry an energy dissipating lead core the rubber in the isolator acts as a spring. In the manufacturing process, rubber is made very soft laterally but very stiff vertically. These two features allow the rubber bearings to move laterally with relatively low stiffness yet carry significant axial load due to their high vertical stiffness.

Types of Rubber Bearings

Following are the main types of rubber bearings:

Plain and Laminated Elastomeric Bearings: Such bearings are manufactured for construction industry in neoprene and natural rubber compound, which is famous for high frequency ground motions.

High Damping Rubber Bearing: This type of bearing is ideal for seismic isolation since it is vertically stiff, capable of supporting vertical gravity loads and capable of allowing large horizontal displacements.

Low Damping Rubber Bearing: This type is made to fit for buildings and widely preferred because of their longevity, economy and better control.

Lead Rubber Bearings: This is stiff and strong in vertical direction and flexible in horizontal direction and helps in providing stability, supports structure and isolates vibrations.

The range of rubber bearings is very important for different application needs.
