Pot Bearing:

Pot Bearings are suitable for high loads, very large displacements and rotations of superstructure. They might accommodate small rotations also. Pot Bearings basically consist of an elastomeric pad restrained in a metallic pot. The pad is then compressed by a piston with bearing pressures on or near to 30 N/mm2 and rotations up to 0.03 rad, depending on the design standard required. When combined with sliding elements, movement capability can be provided in either one or both direction.

Advantages:

1. Easy Installation

2. Easy Inspection

3. Maintenance Free

Types of Pot Bearing:

Pot Bearings are split into three main types:

• Fixed Pot Bearing (TF)

• Guided Pot Bearing (TGa)

• Free Sliding Pot Bearing (TGa)

1-Fixed Pot Bearing (TF):

The basic function of the fixed type is to accept the huge amount of the horizontal loads, thus typically a high capacity attachment system is required. This can be achieved by the use of a bolt / socket system or by being directly bolted to cast in attachment plates.

2- Guided Pot Bearing (TGa):

Guided Pot Bearing are identical in construction to free sliding bearings but are also fitted with one or more guides to limit the bearing’s movement to only one direction.

3- Free Sliding Pot Bearing (TGa):

They are same in construction to the fixed bearings; these multi-directional devices are fitted with a virgin PTFE (Teflon) sheet in contact with the steel plate, enabling the bearing to slide in all directions.
