Advance Roller Shaft

Advance Roller Shaft

The Terex 12599 Trunnion Roller Shaft is a critical component for the pedestal roller assembly on Terex Advance front discharge concrete mixers. This shaft is installed within the drum roller (Terex part 12598), and supports the bearings that allow the drum to rotate smoothly under heavy loads. Replacement is necessary when the shaft becomes worn, bent, or damaged, which can cause excessive vibration, improper drum alignment, and premature failure of the roller bearings and seals.
