Bearings:

• Deep groove ball bearings
• Insulated bearings
• Hybrid ceramic ball bearings,

Mercken Inc. provides bearings with oxide ceramic insulating layers on the bearing ring.
Applied with plasma technology, the insulation has a guaranteed breakdown resistance of at least 1000V AC or DC. Two variants are available:

• Insulation on the outer ring
• Insulation on the inner ring

Advantages of using Insulated Bearings:
 

• Higher operational reliability through optimum protection against electrical Corrosion

• More economic than, for example, insulation on housings or shafts
• Interchangeable: Same key dimensions and technical properties as conventional bearings
• Coating resistant to damage if correctly handled

Typical applications

• Traction motors of railway vehicles
• Electric motors (AC/DC)
• Generators (e.g. in wind turbine generators)
