Thanks for your invitation

If there is heavy duty work ( high speed, high torsion),or high temperature they prefered used iron bearing.

Pot bearings are preferred over elastomeric bearings in situations where there are chances of high vertical loads in combinations of very large angle of rotations. Elastomeric bearings always require a large bearing surface so that a compression is maintained between the contact surfaces in between the piers and the bearings. This is not possible to maintained in high load and rotation environment. Also the usage of elastomeric bearings leads to the uneven distribution of stress on the piers. This results in some highly induced stresses to be targeted at the piers henceforth damaging them. Due to the above reasons pot bearings are preferred over elastomeric bearings in such cases.

 In case of high vertical and/or horizontal loads ,

and when we need  small bearing surface area with ability of uniform distribution of loads on contact piers surfaces
