RIS-2709-RST Iss 2

This document sets out requirements and guidance for the identification and recording of roller bearing defects at overhaul, for taper, cylindrical and spherical roller bearings during overhaul in a maintenance workshop.

More photographs have been added to the revised RIS-2709-RST showing acceptable and rejectable bearing defects to assist the overhaulers in assessing them. Focus has been given to freight wagon bearing defects as the majority of axle bearing overhauls take place on freight bearings. Guidance has been provided to assist overhaulers in qualifying the bearing components for overhaul, particularly on the life of cage material.
