Which type of bearing utilizes a neoprene pad or disk?

Answer: A — Pot bearing

Pot bearings are designed to accommodate movements and rotations in bridge structures while providing support. The key feature of pot bearings is their use of a neoprene pad or disk, which is integral to their function. The neoprene pad serves as a flexible element that can compress and flex under varying loads and movements, offering a degree of flexibility that enhances the performance of the bearing. This type of bearing is particularly useful in allowing for thermal expansion and contraction of the bridge while providing load distribution. The neoprene material also helps to mitigate vibrations and impacts from traffic, contributing to overall structural safety and longevity. The presence of neoprene in pot bearings differentiates them from other types of bearings that either do not use this material or operate on different mechanical principles.
