AI Technical Summary
Technical Problem
Roller bearings in industrial machines face contamination issues, leading to reduced bearing life and frequent maintenance needs, despite existing external seals that are insufficient to prevent contamination entry.
Method used
The integration of a floating-type labyrinth seal on the cage ring of the roller bearing assembly, which maintains the existing mounting and dimensions of the bearings, assembly procedure, and abutment parts, effectively preventing contaminants from entering the bearings.
Benefits of technology
The integrated labyrinth seal effectively prevents contamination entry into the roller bearings, enhancing their lifespan and reducing maintenance needs while maintaining the existing assembly and dimensions.
