7204C/AC精密角接触球轴承，外形尺寸为20*47*14mm。洛阳精密轴承集团***生产供应P2,P4级精密主轴轴承，主要产品包括精密角接触球轴承70系列、719系列、72系列，精密圆柱滚子轴承N10系列.角接触轴承的特点是它既能承受径向载荷又能承受单方向轴向轴向载荷。接触角越大，承受轴向载荷越大，接触角越小，承受轴向载荷就越小。反之，接触角越小，承受径向载荷的能力越大，也越适用于高速应用的场合。根据不同工况条件，它可以有多种组配方式以获得不同的承受径向和轴向载荷能力，并满足高转速和径、轴向高刚度的要求。因此它被广泛应用于精密机床的主轴中。角接触球轴承配对形式有如下6种：1、背对背配置，后置代号为DB（如70000/DB）2、面对面配置，后置代号为DF（如70000/DF）3、串联配置，后置代号为DT（如70000/DT）4、三联配置，后置代号DBD(70000/DBD)5、四联配置，后置代号DBB（70000/DBD）6、***配置，后知代号为DU以下是为您推荐的部分型号：轴承型号外型尺寸额定符合极限重量≈dDBrminr1minaCrCor脂油Mm≈KNr/minKg7204C2047141.00.31213.19.634000500000.117204AC2047141.00.31512.69.230000450000.117205C2552151.00.31316.813.130000450000.147205AC2552151.00.31616.112.526000400000.147206C3062161.00.31423.418.824000380000.217206AC3062161.00.31922.31820000340000.217207C3572171.10.61625.822.91800030000.317207AC3572171.10.62124.521.917000280000.317208C4080181.10.61734.130.917000280000.47208AC4080181.10.62332.529.515000240000.47209C4585191.10.61835.533.816000260000.457209AC4585191.10.62535.832.314000220000.457210C5090201.10.61943.340.615000240000.497210AC50100211.50.62641.338.714000220000.497211C55100211.50.62153.651.114000220000.657211AC55100211.50.62951.148.813000200000.657212C60110221.50.62255.856.212000190000.867212AC60110221.50.63153.053.511000180000.867213C65120231.50.62467.569.011000180001.087213AC65120231.50.63364.265.89500160001.087214C70125241.50.62570.274.610000170001.197214AC70125241.50.63566.671.19000150001.197215C75130251.50.62672.780.29500160001.297215AC75130251.50.63668.976.38500140001.297216C80140262.01.02886.596.59000150001.587216AC80140262.01.03982.191.98000130001.587217C85150282.01.03097.4107.58500140001.967217AC85150282.01.04292.5102.47500120001.96)
