KULPSVILLE, Pennsylvania -- SKF has developed a coating to resist wear that also insulates against stray electric currents on rolling bearings. The company says that all coated bearing boundary dimensions conform to ISO and ABMA standards and can easily replace non-insulated bearings without requiring design changes or rework prior to normal mounting.
SKF says the patented NoWear coating applied on contact surfaces can withstand severe operating conditions due to sudden load and speed variations, poor lubrication conditions from high temperature or low lubricant viscosities, vibration, smearing, and/or solid particle contamination.
The insulating properties of the INSOCOAT rolling bearings protect against potential damage caused by the passage of AC or DC electric current, says the company. Applications include variable speed motors, generators, and associated motor-driven equipment.
