| Can bear the load bearing their direction or nominal contact angle is divided into: ( 1 ) radial bearings - mainly used to bear radial load bearing , its nominal contact angle from 0 ° to 45 °. Nominal contact angle is different, is divided into: radial contact bearings - nominal contact angle of 0 ° radial bearings ; centripetal angular contact bearings - nominal contact angle greater than 0 ° to 45 ° of radial bearings . ( 2 ) thrust bearings - mainly used for axial load bearing , its nominal contact angle greater than 45 ° to 90 °. Nominal contact angle is different, is divided into: axial contact bearings - nominal contact angle of 90 ° thrust bearing ; thrust angular contact bearings - nominal contact angle greater than 45 ° but less than 90 ° thrust bearing . For more information, please refer >>> classified according to the type of rolling bearing structure 2 Press Rolling size classification Bearing their outer diameter size, divided into: ( 1 ) miniature bearings - nominal diameter size range of 26mm or less bearing ; ( 2 ) small bearings - nominal diameter size range of 28 ~ 55mm bearings ; ( 3) small bearings - nominal diameter size range of 60 ~ 115mm bearings ; ( 4 ) large bearing - nominal diameter size range of 120 ~ 190mm bearings ; 3 By Application Use classification can be divided into two categories: 1. General Bearing 2 . Bearings bearings include: 1. General Bearing : is the above one , twenty-two classification to points . 2 . Special bearings : that is used by the occasion to points . Usually divided into : ( 1 ) rolling mill bearings : rolling mill can be divided into two-roll mill , four- and six- roll rolling mill roll mill until 20 . Roller bearing means mounted on both ends of the work roll and the backup roll bearing journal . Roller bearings to withstand large radial rolling force and the installation of roller bearing and radial space is limited , so use a multi-row roll roller bearings to withstand high radial forces , sometimes with angular contact ball bearings or thrust bearings to withstand axial force. The main uses four tapered roller bearings , four-row cylindrical roller bearings and spherical roller bearings. 4 by using the characteristics Category ①. High temperature bearings , working temperature higher than 120 ℃ high temperature bearings bearings . High-temperature bearings are mainly used in aviation jet engines , nuclear reactions in reactors , X-ray tubes, semiconductor device manufacturing equipment and various melt coating equipment. ②. Cryogenic bearings , working temperature below -60 ℃ low temperature bearings bearings. Typical applications are all kinds of liquid gas pump , such as liquefied natural gas pumps, liquid nitrogen ( hydrogen and oxygen ) pump , butane pump , pump liquid rocket missiles , spacecraft and so on. Common cold , mostly single bearing structure deep groove ball bearings and cylindrical roller bearings. 5 bearings While the combination of the above set of bearings bearing structure made of two forms bearing. Such as needle and thrust cylindrical roller bearings, needle roller and thrust ball bearings , needle roller and angular contact ball bearings. Several combinations of bearings : 1 without inner needle and thrust ball bearings without inner needle and thrust ball combination with the cover 3 has two bearing inner ring with roller and ball bearings thrust cover . . 6. Bearing Type Deep groove ball bearings Angular contact ball bearings Self-aligning ball bearing thrust ball bearing thrust angular contact ball bearings Cylindrical roller bearings Needle roller bearings tapered roller bearings Spherical roller bearings Thrust cylindrical roller bearings Thrust needle roller bearings Thrust Tapered Roller Bearings Thrust Spherical Roller Bearings |
