耐高温轴承与普通轴承的型号是有区别。一般分两种情况:
1.轴承的零件由轴承钢制造经高温回火处理的,其后置代号按JB/T2974的规定(零件经高温回火处理,工作温度可达150C°,其置代号为/S0;零件经高温回火处理,工作温度可达200°C,其置代号为/S1;零件经高温回火处理,工作温度可达250°C,其置代号为/S2;零件经高温回火处理,工作温度可达300°C,其置代号为/S3;零件经高温回火处理,工作温度可达350°C,其置代号为/S4)。
2.轴承的零件由耐热钢制造,其后置代号按JB/T2974的规定(材料为Cr4Mo4V,其后置代号为/HN;材料为Cr14Mo4,其后置代号为/HN1;材料为Cr15Mo4V,其后置代号为/HN2;材料为W18Cr4V,其后置代号为/HN3)。
