Bridge Bearing Pads are specially designed with one or multiple layers of elastomers that are bonded to internal steel laminates. These bearing pads are widely used in the construction of bridges and other structures for bearing the vertical load. These elastomeric bearing pads are available in compliance with the latest standards of IRC : 83 (Part II) – 1987.

Construction
Raw materials used in the bearing is poly- Chloroprene from the following brands:
Rubber Bearing consists of alternating laminations of thin rubber layers and steel plates , bonded together to provide vertical rigidity and horizontal flexibility. Vertical rigidity assures the isolator will support the weight of the structure, while horizontal flexibility converts destructive horizontal shaking into gentle movement. Rubber Bearings are used not only for propeller shaft but for cutter shaft head of dredging vessels. Besides the above ,Rubber Bearings are applied for vertical pump shafts.
Our bearings are used on various vessels such as cargo boats, ferry boat, tug boats, pusher boats, navy ships, fishing boats with approvals from LR,ABs, BV,NV, CR, NK respectively.
Recently the demands for Rubber Bearings are increasing in place of Lignum Vitae on account of a sharp rise in price and abnormal abrasion of Lignum Vitae. Our bearings with quality rubber do not damage the shaft sleeve and offer smooth rotation of the shaft over a long period of time.
