Based　on　the　elastohydrodynamic　lubrication　(EHL)　theory,　the　EHL　mathematical　model　of　point　contact　for　angular　contact　ball　bearing　is　established.　The　comprehensive　calculating　method　and　its　corresponding　program　were　given　for　calculating　the　maximum　pressure　and　minimum　thickness　of　oil　film　in　angular　contact　ball　bearing.　Taking　7006　bearing　as　an　example,　the　results　show　that,　compared　with　full-steel　and　full　ceramic　angular　contact　ball　bearing,　oil　film　is　the　thickest　in　hybrid　ceramic　angular　contact　ball　bearing,　oil　film　pressure　is　the　least　in　hybrid　ceramic　angular　contact　ball　bearing,　temperature　rise　is　the　lowest　in　full　ceramic　angular　contact　ball　bearing;　comprehensive　analysis　shows　that　lubrication　property　of　hybrid　ceramic　angular　contact　ball　bearing　is　best　in　these　three　kinds　of　angular　contact　ball　bearings.　In　order　to　investigate　the　effect　of　different　ceramic　materials　parameters　on　bearing　EHL,　six　kinds　of　full　ceramic　bearings　are　further　analyzed.　Oil　film　is　the　thickest　in　bearing　with　SiC　ball　and　ZrO2ring;　oil　film　pressure　is　minimum　in　bearing　with　SiC　ball　and　ZrO2ring,　temperature　rise　is　the　lowest　in　bearing　with　Si3N4ball　and　ring.　Analysis　shows　that,　the　ball　density　has　great　influence　on　bearing　EHL　because　of　speed　effect;　synthetic　elasticity　modulus　is　also　an　important　factor,　the　bigger　synthetic　elastic　modulus　is,　the　thicker　film　thickness　is,　however,　too　high　elasticity　modulus　leads　to　stress　concentration,　which　also　make　the　pressure　rise;　it　is　also　found　that　specific　heat　capacity　has　the　most　influence　on　bearing　temperature　rise.　©　2016　Taylor　and　Francis　Group,　London.
