High pressure resistance to wear and seizure.
Bearing manufactured from steel with a cross- hatched configuration of the bearing surface and a thermo- chemical surface treatment plus impregnation. This bearing has an excellent resistance to wear and seizure and is particulary suitable for very high contact pressures.
Surface characteristics
The friction area has a multitude of interconnecting channels, preferentially oriented in the direction of motion. These channels provide a reservoir of lubricant in case of random lubrication, a better load distribution, and and efficient removal of abrasive particles from the contact. The thermo- chemical treatment plus impregnation provides a high surface hardness, a good conformability and an excellent resistance to wear and seizure.
