AAR APPROVES REMOVAL OF CAP SCREW SEAL RINGS FROM BEARING ASSEMBLY
Effective May 1, 1988, the Association of American Railroads - Mechanical Division has prohibited the application of cap screw seal rings in bearing assemblies. Research performed by BRENCO provided the basis for Roller Bearing Manufacturer's Engineer's Committee recommendations to the AAR to improve bearing performance. Elimination of the cap screw seal ring increases the effective clamping force on the bearing. Increased clamp reduces the possibility of the bearing components loosening in service and causing overheating and failure.
