                              洛陽磐龍軸承有限公司--滾動軸承型號代號

                  基本代號用來表明軸承的內徑、直徑系列、寬度系列和類型,一般最多為五位數,先分述如下:

              1)軸承內徑用基本代號右起、二位數字表示。對常用內徑d=20~480mm的軸承內徑一般為5的倍數,這兩位數字表示軸承內徑尺寸被5除得的商數,如04表示d=20mm;12表示 d=60mm等等。對于內徑為10mm、12mm、15mm和17mm的軸承,內徑代號依次為00、01、02和03。對于內徑小于10mm和大于500mm 軸承,內徑表示方法另有規定,可參看 GB/T272—93。

              2)軸承的直徑系列(即結構相同、內徑相同的軸承在外徑和寬度方面的變化系列)用基本代號右起第三位數字表示。例如,對于向心軸承和向心推力軸承,0、1表示特輕系列;2表示輕系列;3表示中系列;4表示重系列。各系列之間的尺寸對比如下圖所示。推力軸承除了用1表示特輕系列之外,其余與向心軸承的表示一致。

              3)軸承的寬度系列(即結構、內徑和直徑系列都相同的軸承寬度方面的變化系列)用基本代號右起第四位數字表示。當寬度系圖13-4直徑系列的對比列為0系列(正常系列)時,對多數軸承在代號中可不標出寬度系列代號O,但對于調心滾子軸承圓錐滾子軸承,寬度系列代號0應標出。直徑系列代號和寬度系列代號統稱為尺寸系列代號。

              4)軸承類型代號用基本代號右起第五位數字表示(對圓柱滾子軸承和滾針軸承等類型代號為字母)。

              2后置代號

              軸承的后置代號是用字母和數字等表示軸承的結構、公差及材料的特殊要求等等。后置代號的內容很多,下面介紹幾個常用的代號。

              1)內部結構代號是表示同一類型軸承的不同內部結構,用字母緊跟著基本代號表示。如:接觸角為15°、25°和40°的角接觸球軸承分別用C、AC和B表示{HotTag}內部結構的不同。

              2)軸承的公差等級分為2級、4級、5級、6級、6X級和0級,共6個級別,依次由高級到低級,其代號分別為/PZ、/P4‘/PS、/P6、/P6X和/PO。公差等級中, 6X級僅適用于圓錐滾子軸承; 0級為普通級,在輪承代號中不標出。。

              3)常用的軸承徑向游隙系列分為1組、2組、0組、3組、4組和5組,共6個組別,徑向游隙依次由小到大。o組游隙是常用的游隙組別,在軸承代號中不標出,其余的游隙組別在軸承代號中分別用/CI、/CZ、/C3、/C4、/CS表示。

              Luoyang Panlong Bearing Co. Ltd. - rolling bearing type

              Basic code used to show that the bearing diameter, series, the width of the series and type, generally up to five digits, first described as follows:

              1) bearing inner diameter with the basic code right, the two digit representation. A multiple of 5 bearing inner diameter of ~ 480 mm diameter d=20 generally. The two figures said the inner diameter of the bearing is 5 in addition to the quotient, such as 04 said D; 12 said d=60mm and so on. For bearings with 10mm, 12mm, 15mm, and 17mm, the inner diameter code is 00, 01, 02 and 03, respectively. For the inner diameter less than 10mm and greater than the 500mm bearing, the inner diameter means that the method can see GB/T272 - 93.

              2) a series of bearings (i.e., the same diameter and width of the same diameter and width of the same diameter) are represented by the third digits of the basic code. For example, for radial bearings and radial thrust bearings, 0, 1, said the special light series; 2 said light series; 3 said in a series; 4 expressed heavy series. The dimensions of the series are shown below. Thrust bearings in addition to the use of a special light series 1, the rest of the same as the radial bearing.

              3) the bearing width series (that is, the structure, inner diameter and diameter series are the same as the change of the bearing width of the series) with the basic code right from the fourth digit representation. When the width of Figure 13 - 4 Diameter series contrast column for series 0 (normal), the most bearing in the code can not mark width series code o, but for spherical roller bearings and tapered roller bearings, width series code 0 should be marked. Series of diameter and width series code name is called the size of the series.

              4) bearing type code is represented by the right of the basic code of the fifth digit (of cylindrical roller bearings and needle roller bearing type code letters).

              2 post code

              The post code of the bearing is used to express the structure, tolerance and the special requirements of the material and so on. Post code of the contents of a lot, the following introduction of several commonly used code.

              1) the internal structure code is the same type of bearing the different internal structure, with the letter followed by the basic code said. Such as: the contact angle of 15 degrees, 25 degrees and 40 degrees of angular contact ball bearing C, AC and B said the {HotTag} internal structure of the different.

              2) the tolerance level of the bearing is divided into 2 levels, 4, 5, 6, 6X and 0, respectively, and the code is /P4, /PS, /P6, /P6X, /PO and /PZ, respectively. In the tolerance level, the 6X level is only suitable for the tapered roller bearing; the 0 stage is the ordinary grade, and the wheel bearing code is not marked..

              3) commonly used radial clearance of the ball bearing series is divided into group 1, group 2, group 0, group 3, group 4 and 5 groups of, a total of six groups, radial clearance progressively larger. O set of clearance is commonly used clearance group and in the bearing designation is not marked, the rest of the clearance group in the bearing designation respectively with / CI, /CZ, /C3, /C4, CS said.
