    Approved by Ministry of Road Transport & Highways (MORTH ) and RDSO Kanta Fiex Elastomeric Elastomeric Bridge Bearings are designed-and manufactured as per IRC: 83 (part II) - 1987 with its latest amendments, to meet the requirements of Mosrt &.H Specification for road & Bridge Works to Section No : 2000 T0 Clause NO : 2005 (Electrometric Bearing) : and to international Union of Railways Code No. U (C 772 R (Use of Rubber Bearings for Railways Bridges). It consists of one or more internal layers of elastomeric bonded to internal steel laminates shall be cast as single unit in a mould and vulcanised under heat & pressure, to cater for translation or rotation of the superstructure by elastic deformation. The raw elastomer used in Bearings are poly-Chloroprene. either of Brands: Neoprene WRT, Bayprene 110, skyprene B 5. &.. Denka S-40V in order to have low crystallization rate and adequate shelf life.
    The content of the Poly Chloroprene in the Bearing is not less than 60% and the ash content shall be less than 5%. The Steel laminates used in the Bearings shall meet the specification of IS : 2062.
    Techinacal Data of Bearings

    • 10 KN is equivalent to I MT.
    • Design load of the bearing is equivalent to 10M Pa.
    • Shear modulus of the bearing shall be between 0.8 &. 1.2 M Pa.
    • Ultimate compressive strength of the bearing shall be more than 60 M Pa.
    • Dimension can also be designed as per requirement.
