needle roller bearings --- - rolling body is needle bearings, needle length to diameter ratio greater than 3, but a diameter less than or equal to 5mm; tapered roller bearings ----- rolling body is tapered roller bearings; spherical roller bearings eleven rolling body is spherical roller bearings. (3) whether the bearing aligning their work is divided into: 1) aligning bearings ----- raceway is spherical shape, able to adapt to angular deviation and angular movement between the two raceways of the bearing axis ; 2) non-aligning bearing (rigid bearing) ----- crystal type diamond able impedance path between roller bearing axis angular offset. (4) according to the number of rows of rolling elements bearings, divided into: 1) single row bearings ----- has a list of rolling element bearings; 2) ----- double row bearings have two rows of rolling element bearings; 3) ----- multi-row bearings with more than two rolling element bearings, such as three, four bearings. (5) whether the separation bearing their part, are divided into: 1) separable bearings ----- bearings with separable components; 2) can not be separated after the final bearing ----- bearing supporting rings are freedom can not be arbitrarily separated bearings. (6) bearing their structure and shape (if no filling slots, without inner and outer rings and structural shapes, ribs, and even whether the cage, etc.) E-grind wire saw diamond can also be divided into a variety of structural types. 2. rolling bearing outside diameter size classification bearing their size, divided into: (1) Miniature Bearings ---- nominal diameter size range of 26mm or less bearing; (2) a small nominal outer bearing ----- diameter size range of 28-55mm bearings; (3) small and medium sized bearings ----- nominal diameter size range of 60-115mm bearings; (4) in the large bearing ----- nominal diameter size range of 120-190mm bearing (5) large bearing ----- nominal diameter size range of 200-430mm bearings; (6) large bearings ----- nominal diameter size range of 440mm or more bearings.
