Bearing Journals and Seal Surfaces

Often bearing journals and seal surfaces have problems with their seals no longer sealing due to wear, this allows foreign liquids and materials into the bearings or lets oil and grease escape.

Selectro’s metal repair process reclaims your components for another full life cycle. We can easily repair and resize both seal and bearing surfaces to original dimensions. Often the repair will contain a harder wearing material than the original part and will therefore last longer. This process can also provide erosion protection for the exposed shaft in harsh environments e.g. Marine and fishing boats.

Apart from being able to keep your original OEM part for a longer period of time, using selective electroplating for your bearing journal and seal surface repairs is more economical, has a faster turnaround with less downtime, and cannot be messed up through an order mistake, version differences, or shipping errors and delays. The repaired and enhanced OEM will fit perfectly back into your machine every time.

In contrast to spray wielding, the strength of the components is not reduced when repaired using our process. Only compromised material will be removed and backfilled, retaining most of the original material. The resulting “molecular” bond has superior adhesion than the “mechanical” bond that is achieved with spray welding process. The bond created between the applied coating and the base material is equivalent to the cohesive strength of the base metal itself.
