A ptfe bridge bearing is an essential component of the interface between the superstructure and substructure of a bridge structure. Because of the nature of the forces that are transmitted between these two structures, the bearing must be able to withstand a variety of conditions including heavy traffic loads and their associated vibrations, daily thermal cycles, and the occasional seismic event. These varied factors can put a significant amount of stress on the bridge bearing design and therefore require a special consideration to the material used to fabricate the bearing.

ptfe bridge bearings offer a unique combination of resilience and performance that can meet these challenges with ease. The bearing carries vertical loads on an elastomeric disc confined in a steel cylinder and accommodates rotational movement through deformations of the elastomer. Unlike other structural bearings, a ptfe bridge bearing is capable of supporting both translation and rotation movement through the use of elastomer deformation and is thus capable of a much greater range of movements than other conventional bearings.

These elastomeric bridge bearings can withstand temperatures up to 1000 degrees Fahrenheit with a coefficient of friction of 0.04 to 0.010. They are also resistant to most system media and have the ability to sustain rubbing speeds as high as 10,000 RPM. They are available in cam follower, pillow block, slide, and linear bearing styles for the analytical instrumentation, sample preparation, life sciences, marine, food processing, and material handling industries.
