Advantages Of NU 1012 ECP/C3VL0241 Insulated Roller bearing
· 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
High-quality coating
A plasma spray technique is used to apply the aluminum oxide layer. Sophisticated
pre- and post- application processes result in an outstanding coating quality.
Protective sealant
EASIER bearings are treated with a unique sealant to guard against humidity penetrating the coating and reducing its effectiveness.
Optimized solutions
TKW can supply values for relevant electric parameters for the bearings (capacitance,
impedance) to optimize the insulating solution for any application.
Principle bearing types for traction motor applications
• cylindrical roller bearings
• electrically insulated cylindrical roller bearings
• electrically insulated deep groove ball bearings
• hybrid cylindrical roller bearings with ceramic rollers
• hybrid deep groove ball bearings with ceramic balls
• traction motor bearing units based on cylindrical roller bearings and
deep groove ball bearings
