Elastomeric Bearings
Elastomeric bearings have been used for more than 60 years in the construction of bridges and are the most widely used type of bearings in India. These bearings are easy to install and can take Vertical loads up to 3800 KN. With more than 30 years of experience in manufacturing elastomeric bearings, Hevea Rubber Technologies Pvt. Ltd. will be your most suited partner in supply of these super-critical bridge components. Hevea Rubber Technologies Pvt. Ltd is prequalified to supply elastomeric bearings for all projects in India, and has been empanelled in MoRT&H (since 2001), RDSO (Since 2006) and DMRC (Since 2012)
POT PTFE
The pot bearing consists of cylindrical Pot, a non-reinforced elastomeric pad which is confined inside the POT, A Piston which is attached to the top of the bearing plate to transfer the load from the bridge deck to the elastomeric pad and a seal to minimize or prevent the elastomeric pad from slipping out of the POT. Since the elastomeric pad is confined within a metallic cylinder, it provides a load carrying medium at the same time providing the bearing with a multidirectional rotational capacity. As such, Pot bearings do not allow any translation movement. In order to permit translational movement in addition to rotation, plain sliding arrangement is provided over the top plate of pot bearing. PTFE in combination with stainless steel is used to design this sliding arrangement. These are commonly referred to as POT cum PTFE Bearings. Hevea has been approved by RDSO for the fabrication and supply of POT / POT-PTFE Bearings for Indian Railways.
Seismic Bearings
Hevea also has the capacity to design, fabricate and supply high damping Seismic bearings for base isolation systems for buildings.
