This part of EN 1337 specifies the requirements for the design and manufacture of pot bearings which will be used for operating temperatures between - 40ºC and 50ºC.
This part of EN 1337 does not apply to pot bearings made with other materials than those specified in clause 5.
Bearings which are subjected to rotation CX(j greater than 0,030 rad (see Figure 2) under the characteristic combination of actions or which incorporate elastomeric pads larger than 1500 mm in diameter are beyond the scope of this document.
Depending on the climatic region where the construction work is located the bearings can be designed to one of the following classes related to minimum operating temperatures (the minimum shade air temperatures): - 25ºC or - 40ºC.
When required to accommodate translational movements, pot bearings may be combined with sliding elements in accordance with EN 1337-2.
