Description of Pot Bearings
|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
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 bearing installation requirements:
(1)the pier top bearing mounting surface uneven, without finishing leveling.
(2) support the center line and elevation without checking, lofting is not allowed.
Features of pot bearings
1.Compact -Low overall height.
2.Compact -Small footprint for significant vertical loads.
3.Small shift in centre of pressure due to rotation.
4.Low translation resistance.
5.Can accommodate lateral loading at same time as translation.
6.Specials - To accommodate up lift loadings.

Technical Performance of pot bearing
1.Vertical rotation angle of the bridge Pot bearing should not be less than 40';
2.Vertical bearing capacity (KN) 1000-50000 of the Bridge Pot bearing is divided into 28 grades. Horizontal bearing capacity of the non-gliding
surface is 10% of the vertical.
3.Friction coefficient of the Bridge Pot bearing: Room temperature μ ≤ 0.04
