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. Types of rubber used in making bearings Natural Rubber Neoprene Butyl Rubber (IIR) Butadiene Rubber (BR) Ethylene Propylene Diene Monomer (EPM, EPDM) Different types of Rubber Bearings Plain and Laminated elastomeric bearings High Damping Rubber Bearing (HDRB) Low Damping rubber bearing: Lead Rubber Bearings (LRB) Applications: Agriculture, Construction, Nuclear & Thermal Power Plants, desalination plants, swearer pumps etc..
