產品描述
1、按滾動軸承結構類型分類 (1) 軸承按其所能承受的載荷方向或公稱接觸角的不同，分為：1)向心軸承----主要用于承受徑向載荷的滾動軸承，其公稱接觸角從0到45。按公稱接觸角不同，又分為：徑向接觸軸承----公稱接觸角為0的向心軸承：向心角接觸軸承----公稱接觸角大于0到45的向心軸承。2)推力軸承----主要用于承受軸向載荷的滾動軸承，其公稱接觸角大于45到90。按公稱接觸角不同又分為： 軸向接觸軸承----公稱接觸角為90的推力軸承：推力角接觸軸承----公稱接觸角大于45但小于90的推力軸承。
2、 軸承按其滾動體的種類，分為： 1) 球軸承----滾動體為球： 2) 滾子軸承----滾動體為滾子。滾子軸承按滾子種類，又分為： 圓柱滾子軸承----滾動體是圓柱滾子的軸承，圓柱滾子的長度與直徑之比小于或等于3 ；滾針軸承----滾動體是滾針的軸承，滾針的長度與直徑之比大于3，但直徑小于或等于5mm; 圓錐滾子軸承----滾動體是圓錐滾子的軸承; 調心滾子軸承一一滾動體是球面滾子的軸承。(3) 軸承按其工作時能否調心,分為: 1) 調心軸承----滾道是球面形的,能適應兩滾道軸心線間的角偏差及角運動的軸承; 2) 非調心軸承(剛性軸承)----能阻抗滾道間軸心線角偏移的軸承。
3.按滾動軸承尺寸大小分類 軸承按其外徑尺寸大小，分為: (1) 微型軸承----公稱外徑尺寸范圍為26mm以下的軸承; (2) 小型軸承----公稱外徑尺寸范圍為28-55mm的軸承; (3) 中小型軸承----公稱外徑尺寸范圍為60-115mm的軸承; (4) 中大型軸承----公稱外徑尺寸范圍為120-190mm的軸承 (5) 大型軸承----公稱外徑尺寸范圍為200-430mm的軸承; (6) 特大型軸承----公稱外徑尺寸范圍為440mm以上的軸承。

1. According to the structure type of rolling bearings, (1) bearings are divided into: 1) radial bearings - rolling bearings mainly used to bear radial load, with nominal contact angle from 0 to 45, according to the load direction they can bear or the nominal contact angle. According to the different nominal contact angles, it can be divided into radial contact bearings - radial bearings with a nominal contact angle of 0; radial angular contact bearings - radial bearings with a nominal contact angle greater than 0 to 45. 2) Thrust bearing - mainly used for bearing axial load, with nominal contact angle greater than 45 to 90. According to the difference of nominal contact angle, it can be divided into: axial contact bearing - thrust bearing with nominal contact angle of 90; thrust angular contact bearing - thrust bearing with nominal contact angle greater than 45 but less than 90.
2. According to the types of rolling elements, bearings are divided into: 1) ball bearings ---- rolling elements are balls; 2) roller bearings ---- rolling elements are rollers. Roller bearings can be divided into cylindrical roller bearings according to the types of rollers. The rolling body is the bearing of cylindrical roller. The ratio of length to diameter of cylindrical roller is less than or equal to 3; Needle-roller bearing - the rolling body is a needle bearing. The ratio of needle length to diameter is greater than 3, but the diameter is less than or equal to 5mm; Tapered roller bearing - the rolling body is the bearing of tapered roller; Self-aligning roller bearing - the rolling body is a spherical roller bearing. (3) Bearing can be divided into: 1) self-aligning bearing - the bearing whose raceway is spherical and can adapt to the angular deviation and angular movement between the axes of two raceways; 2) Non-aligning bearing (rigid bearing) - a bearing that can resist the angular deviation of the axis between the raceways.
3. According to the size of rolling bearings, bearings can be divided into: (1) miniature bearings - bearings with a nominal outer diameter of less than 26mm; (2) Small bearings - bearings with a nominal outer diameter of 28-55mm; (3) Medium and small bearings - bearings with nominal outer diameter ranging from 60 to 115mm; (4) Medium and large bearings - bearings with a nominal outer diameter of 120-190mm (5) large bearings - bearings with a nominal outer diameter of 200-430mm; (6) Extra large bearing - bearing with nominal outer diameter of more than 440mm.
