Rocker Cum Roller Bridge Bearings

Metallic bridge bearing are the basic type of bearings which came into existence with the commencement of bridge construction. The metallic Bearings are widely used because of their time reliability, stable performance and simplicity in design.
CECO presents the complete range of metallic Bearings, viz Mild Steel, Cast Steel. Roller - Rocker Bearings, Fixed and Sliding Plate Bearing, Hinge and Knuckle-Leaf Bearing.
MS Sliding Plate Bearings : Are the simplest bearing where the upper plate is attached to bottom of the girder/beam, slides over another plate. On account of very large, frictional forces involved and lack of provision for beam rotation, the use of this type of bearing is restricted.
Rocker & Roller Bearing : Consist of one or more roller of steel along with a rocker arrangement which permits a longitudinal and rotational movement. Raw materials for MS bearings are tested for are IS: 2062 grade.
Properties such as correct smoothness and curvature are obtained with strict attention to quality control. Each bearing is also tested for 125% of the designed capacity load.
Cast/Forged steel Rocker & roller Bearings : Are similar the MS type, the only difference is the use of cast/forged steel in its manufacture. This gives it a greater load-bearing capacity than a MS bearing of the same size.
