Hevea HEVEX SSEJ 80 ® expansion joints are single gap expansion joints for movements of up to 80 mm. The joint caters to the design parameters mentioned in IRC 69 SP:2011. The steel edge profiles of are anchored using high tensile bolts to prevent any malfunctioning. Hevea has a team of engineers who are trained to fix expansion joint at site. We are Pre-qualified to supply to Railway bridges and have been approved by RDSO since 2014.

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)

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.

D-Type Rubber Fenders are used widely for low to medium impact or lower energy absorption applications. These types of fenders are used for workboats, Fishing Boats, Tugboats, Loading stations, etc. At Hevea, we can extrude up to 250x250 type D Fender.

W Type fenders are used for high loads and to absorb excessive dynamic stresses. These type of heavy duty Fenders are manufactured by Compression Moulding. The rubber compound will be both abrasion resistant as well as highly durable.

Hevea supplies Special multi-purpose industrial rubber hoses for various industries such as dredging, mining, shipping, construction and chemical industries. Hevea group of companies have been manufacturing industrial grade hoses for the past 30 years.

The basic polymer is either natural rubber or Styrene Butadiene Rubber or a blend of both these polymers, as per the instructions of the client. The seals are sometimes cladded with Teflon, mainly to reduce the frictional forces.

Hevea has more than 200 different dies for various rubber profiles. Our profiles are widely used in the construction, ship repairs and automotive industry. We have our own integrated die making facility.
