  • Bearing basics

    The small contact area provides low rolling friction, which enables ball bearings to accommodate high speeds but also limits their load-carrying capacity. Rollers make line contact with the ring raceways . With increasing load acting on the bearing, the contact line becomes somewhat rectangular in shape. Because of the larger contact area and ...

  • ROLLING BEARING LUBRICATION

    2020-10-27u2002·u2002Rolling Bearings The lubrication of rolling bearings – similar to that of sliding bearings – main-ly serves one purpose: to avoid or at least reduce metal-to-metal contact between the rolling and sliding contact surfaces, i.e. to reduce friction and wear in the bearing. Oil, adhering to the surfaces of the parts in rolling contact, is fed ...
