1. Roller bearing scheme by identify (1) its bearings crapper bear the alluviation or the direction that the occurrence seek different, namely: to the hunch bearing —- mainly utilised for symmetric alluviation to bear the Rolling, said the occurrence seek from 0 to 45. By the occurrence seek assorted from that, is distributed into: symmetric occurrence bearings —- minimal occurrence seek of 0 to the hunch of the bearings: asteroid occurrence bearings to the hunch —- said the occurrence seek greater than 0-45 to the hunch of the bearings. —- Main oblige bearing stem alluviation to bear for the Rolling, said the occurrence seek greater than 45 to 90. By the occurrence seek that is distributed into different: stem occurrence with the bearing —- said the occurrence seek of 90 oblige bearing: Thrust asteroid occurrence bearings —- said the occurrence seek greater than 45 but inferior than 90 of the oblige bearing. (2) of actuation bearings according to the type, distributed into: ball bearings —- for the ball actuation in: roller bearings —- actuation in for the roller. Roller bearing on roller type, is distributed into: rounded roller bearings —- actuation of the rounded roller bearings and rounded roller filler and diam ratio of inferior than or coequal to 3; harry roller bearings — – Is a harry roller bearings, harry filler and diam ratio of greater than 3, but the diam of inferior than or coequal to 5 mm; narrow roller bearings —- actuation of the narrow roller bearings; aligning roller Jan 1 roller bearing is spherical roller bearings. (3) bearing their impact crapper set heart, is distributed into:-aligning roller bearings —- Road is spherical shape, the digit crapper foregather Raceway axis distinction between the deflexion and locomote bearings; non-transfer Heart bearings (rigid status to roller bearings )—- axis distinction Kok Road equilibrize the bearing. (4) of actuation bearings on the sort of rows, distributed into: a azygos bed bearings —- a holograph bearing the body; Dual-out bearing —- with digit roller bearings; are bearing more than a —- solon than digit roller bearings, much as three, quaternary bearings. (5) bearing their components crapper separate, distributed into: clastic bearing —- with clastic parts of the bearing; crapper not be distributed bearing —- bearings in the test matching, the Ring crapper not be liberated from capricious bearings . (6) bearing scheme of its appearance (if there is no weight slot, whether in the appearance of the outmost ring and ring, the scheme of ribs, or modify whether Cage, etc.) crapper be distributed into different types. 2. Classified by filler Rolling bearing their diam size, are: micro-bearings —- minimal filler of the diam of 26 mm beneath the bearings; diminutive diam bearing —- minimal filler arrange of 28-55 mm The bearings; diminutive and medium-sized bearings —- minimal right diam filler arrange of 60-115 mm bearings; job and super diam bearing —- minimal filler arrange of 120-190 mm of bearing super diam bearing —- minimal filler The arrange of 200-430 mm of bearing; super diam bearing —- minimal filler arrange of 440 mm over the bearings.
