轴承的制造工序

Manufacturing Process of Bearing

1. 轴承主要材质:1. 轴承钢:高碳烙轴承钢(SUJ2 →小型钢材;SUJ3 →大型钢材; SUJ4 →特殊型钢材;

Main material of bearing: 1. Bearing steel: High carbon bearing steel (SUJ2→light shape; SUJ3 →heavy section; SUJ4 →special type steel)

2. 精度要求:国际标准1. 内径公差:Φ20以上,0~-10um2. 外径公差:0~-10um3. 厚度公差:0~-120um 一般在3040注:内径越大外径公差越大。3. 轴承韧处理:1. 内外环表面硬度:HRC5862°2. 钢珠表面硬度:HRC6064°

2.Precision requirement: International standard 1. ID tolerance: Above Φ20, 0~-10um 2. OD tolerance: 0~-10um 3. Thickness deviation: 0~-120um, generally 30-40. Remark: The bigger the ID, the bigger the tolerance is. 3: Bearing toughening treatment: 1. Internal and external ring surface hardness: HRC5862° 2. Steel ball surface hardness: HRC6064°.

3. 内径尺寸备注:尾数在04以上的都要=2位数*5,尾数在04以下的内径尺寸比较特殊,如下:03==17 02==15 01==12 00==10 前面是代号,后面是内径尺寸。3、密封板代码如下:密封板分为、铁密封圈、橡胶密封圈。(见书A50Z 代表 单面防尘盖 ZZ 代表 双面防尘盖 ZX 代表 单面防尘盖(带弹簧挡圈) ZZX代表 双面防尘盖(带弹簧挡圈)RU 代表 单面非接触式密封圈 2RU 代表 双面非接触式密封圈RS 代表 单面接触式密封圈 2RS 代表 双面接触式密封圈RD代表 单面超轻接触式密封圈 2RD代表 双面超轻接触式密封圈ZU 2ZU(非接触式密封圈) RK 2RK U UU (接触式密封圈)

3. Inner diameter dimension remarks: If the mantissa is bigger than 4, the inner diameter will be mantissa*5; If the mantissa is smaller than 4, the inner diameter will be special: 03==17 02==15 01==12 00==10, The front is the code, and the back is the size of the inner diameter. 3. The seal plate code is as follows: The sealing plate is divided into iron sealing ring and rubber sealing ring. Z represents one side dustproof cover. ZZ represents double face dustproof cover. One - sided dust - proof cover ( with spring retainer ). ZZX represents a double face dustproof cover (with a spring ring). RU stands for single - sided non - contact sealing ring. 2RU represents a double-sided non contact seal. RS represents one-sided contact sealing ring. 2RS represents double contact seal ring. RD represents one side ultra light contact seal ring. 2RD stands for double - sided ultra - light contact sealing ring. ZU2ZU (non-contact sealing ring) and RK 2RK U UU (contact seal ring).
