Technical Manual

Storage, Handling & Installation

Proper storage, careful handling and correct installation are essential to maintain the condition and performance of Elastomeric Bearings.

The guidelines below cover the recommended practices for storing, handling, transporting and installing the bearings as specified for the product.

Pedestal Leveling
Leveling tolerance within ±1mm with non-shrink epoxy bedding mortar.
Synchronized Jacking
Even girder load transfer preventing edge crushing and eccentric rotation.
Annual In-Service Inspection
Checklist for elastomer shear strain, bulging, weathering, and grease condition.
Authority Approval
Standard methodology accepted across NHAI, Rail, Metro, and State PWD projects.
