Uplift Bearings

Home»Bridge Bearings»Uplift Bearings


Disktron Bearings can be easily modified for uplift restraint which is common in seismic zones. Uplift forces are also seen on some curved girder bridges and in flood prone regions where high water can result in the bridge becoming buoyant. The standard central pin or SRM on the Disktron Bearing is modified so that the upper and lower bearing plates cannot separate. This SRM acts like a trailer hitch on an automobile.  For expansion bearings the upper slide plate is modified so that it lips under the upper bearing plate to resist the uplift force. Fully assembled the modified Disktron Bearing can accommodate uplift load, movement and rotation simultaneously which is a feature unique to this type of bearing.
