  • Rolling Bearing Lubrication for Critical Running Conditions

    In order to ensure good lubrication, most spherical roller bearings have a circumferential groove and three lubrication holes in the outer ring. The lubricant is pressed into the bearing via the groove and holes Figure. Due to the direct and symmetrical feed system, a uniform supply of lubricant to the rows of rollers is achieved.
