Challenge Roller Spacer

Challenge Roller Spacer

This roller spacer is a critical component used within the drum roller assembly (Challenge P/N: 5002358) on rear discharge concrete mixers. It is installed on the roller shaft to ensure correct spacing and alignment of the bearings, seals, and the bare roller, which is essential for smooth drum rotation. Replacement is necessary during a complete roller rebuild or when the original spacer is worn or damaged, which can lead to premature bearing failure or improper drum alignment. Two of these spacers are typically required per roller assembly.
