Scope

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 –25 °C and +50 °C or –40 °C and +50 °C,—subjected to operating temperatures up to +70 °C 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.
