Introduced nearly 50 years ago, Pot Bearings are now in service in thousands of structures throughout the USA and the world. There are good reasons for this popularity, all stemming from the confined elastomer principle. The elastomeric Pot Bearing consists of a confined disk of elastomer within a short cylinder (the pot). Loading is then applied via a close fitting steel 'piston'. This puts the elastomer under high pressure,making it behave like a liquid, permitting rotation in any direction with very little resistance. |

Pot type rubber bridge bearing can be used in steel or concrete structures. These low profiles, compact bearings are particularly useful to transmit large vertical load while accommodating large movements and multi-directional rotation.Separate mechanisms for rotation and translation (where applicable) provide minimum eccentricity of the load and minimum frictional resistance to movement. High side loads can also be accommodated simultaneously. |
