  • Journal Bearing VS Ball Bearing - Hybrid Turbos.com

    2012-6-13 · Competitor Ball Bearing Options – Another option one will find is a hybrid ball bearing. This consists of replacing only the compressor side journal bearing with a single angular contact ball bearing. Since the single bearing can only take thrust in one direction, a thrust bearing is still necessary and drag in the turbine side journal ...

  • TURBO CHOICE? Journal Bearing vs. Ball Bearing |

    The piston pin-bore bearing also acts as a form of journal bearing, so do the big-end bearings, covered in Chapters 19 and 20. Journal bearings usually operate in a hydrodynamic regime of lubrication as the generated pressures are low compared with those experienced by ball and rolling element bearings, gears and cam–follower pairs.
