Elastomeric Bearings

Arfen elastomeric (neoprene) bearings, consisting of a waterproof rubber and steel plates which transfers the loads rightly from superstructure to the bridge piers and abutments. This system produces in factory under high temperature and pressure with natural rubber (NR) or chloroprene (CR) plates (in some cases only rubber) and steel plates. The rubber material with vulcanized steel plate is used to obtain composite and strong system against loads. The system provides corrosion-guaranteed and long-lasting solution to Arfen bridge bearings. Rubber has a resistance against surface oil, grease, oil, chemicals, resistant to UV-rays, snow and salt. All of these bearings are designed and manufactured accordance with recent technology to transfer every kind of loads (traffic load, seismic load, wind load, etc.) from the upper structure to the piers of the bridges. The outer surfaces of the type B elastomeric bearings are entirely covered with rubber. They are used in both concrete and steel construction elements and the type of bearing can be placed between the structural members easily. C type bearings have lower and upper steel plates. These plates are fixed to the structure with bolts to ensure the safety of the system against shear forces. The inner steel plates in the bearings must be at least 2 mm. If sliding type of bearing is requested, it can be designed according to standards using PTFE and stainless steel by our professional engineers. Outer steel plates are used in these bearings. The thickness of the outer steel plate varies according to the design loads and displacements. Our products are manufactured in accordance with BS 5400, DIN 4141, EN 1337-3 and AS 5100-4. All the tests required from the beginning to the end of the manufacturing are done in our own laboratory.

Bearing selection can be done from tables in pages or related design needs can be sent to our company to produce special sizes for your need.
