VOLVO FLANGE BEARING 24051715

Function and technical context

Flange bearing 24051715 acts as a radial support element for the drive shaft in the propulsion system of Volvo Penta D4 and D6 series marine engines. Mounted in a flange configuration, it guarantees precise alignment of the drive shaft during rotation, absorbing the radial loads generated by power transmission and vibrations typical of the marine environment. Its correct function is decisive for the integrity of the entire drive train: a deteriorated bearing causes progressive misalignment of the shaft, increased vibrations in the hull, accelerated wear of seals and adjacent joints, and in advanced cases it can cause structural damage to the transmission box or the drive shaft itself. It is a precision part specially designed to withstand the dynamic stresses of medium and large displacement diesel engines in marine propulsion applications.

When to replace this part?

The most common symptoms of wear in a propeller shaft flange bearing are unusual vibrations noticeable in the hull or controls, metallic noise or hum while sailing at different speeds, and excessive play detectable when manually moving the shaft with the engine stopped. It is recommended to inspect this component during each seasonal maintenance or every 300-400 hours of navigation, coinciding with the inspection of the transmission system. Replacing the flange bearing preventively, before wear becomes evident, avoids chain failures in stern tube seals, transmission joints and couplings that can lead to high-cost repairs or an unscheduled technical stoppage at sea.
