ROLLER-REACH (Komatsu KO1901-55049)

A worn reach roller can cause uneven load handling and increased wear on guide surfaces. This aftermarket replacement part references Komatsu as the OE maker and cross-references part number KO1901-55049. The roller is a type-level component that supports linear motion along a reach mechanism. Its plain mechanical function is to reduce friction during extension and retraction. A generic failure consequence is that a seized roller may lead to jerky movement or binding. Keeping the roller in sound condition helps maintain smooth operation.
