pot bearing

A pot bearing consists of rubber pad, top plate, piston, pot, sliding materials and so on.

A pot bearing consists of rubber pad, top plate, piston, pot, sliding materials and so on. It can take vertical load, lateral force, movement and rotation.

Pot-type bridge bearings – fixed or sliding – can accommodate rotations of up to 0.040 radians in any direction and can be designed to accommodate any horizontal load or displacement. A pot bearing consists of a shallow/hollow steel cylinder, or pot, with an elastomeric disc, slightly shorter than the steel cylinder, fitted snugly inside. A steel disc, or piston, fits inside the steel cylinder and bears on the elastomeric disc. Flat brass sealing rings are used to contain the elastomer inside the pot. The elastomer behaves like a viscous fluid flowing within the pot as rotation occurs.
