This document specifies rules for the design@ testing and manufacture of fixed and sliding pot bearings. It is applicable to pot bearings: ?? with elastomeric pads made from natural rubber (NR) or chloroprene rubber (CR) up to 1 500 mm diameter@ ?? with pot and piston made from ferrous materials@ ?? with seals tested for different accumulated slide paths due to rotations between piston and pot of a) 500 m@ b) 1 000 m or c) 2 000 m@ ?? with seals made from specific austenitic steel@ brass@ POM or carbon filled PTFE@ ?? subjected to operating temperature ranges between ?C25 ??and +50 ??or ?C40 ??and +50 ?? ?? subjected to operating temperatures up to +70 ??for repeated periods of less than 8 h. This document will be used in conjunction with prEN 1337-1:2018 and other relevant parts of the prEN 1337 series.
