BEARING SEPARATOR 30-50mm

Function and technical context

The bearing spacer acts as an axial positioning element within the marine transmission line bearing assembly, maintaining precise spacing between adjacent bearings so that each one works in its correct position. It operates in the power transmission system, specifically in the area of ​​the tail or output shaft, where the radial and axial forces are constant during navigation. The dimensional range of 30 to 50 mm makes it suitable for medium power marine engines, offering installation versatility in different transmission configurations. If this component fails or wears out, the bearings lose their axial positioning, causing irregular contact between races, vibration in the shaft line, characteristic metallic noise and, in advanced cases, the collapse of the bearing assembly with consequent damage to the shaft and housing. The reference of this component is REC91-00001.

When to replace this part?

The most common symptoms indicating deterioration of a bearing separator include unusual vibration or metallic hum coming from the transmission area, excessive axial play detected when manually moving the shaft, and abnormal heating in the bearing area after periods of navigation. It is recommended to inspect this component during each seasonal maintenance, especially when the bearings are dismantled for inspection or replacement, since taking advantage of this intervention to check the condition of the separator avoids a second opening of the assembly. Replacing the separator preventively when the bearings are renewed guarantees the integrity of the transmission assembly and prevents navigation breakdowns that would be considerably more expensive to resolve outside the workshop.
