71904C/AC角接触球轴承，外形尺寸20*37*9mm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-719系列型号外形尺寸〆15o〆25o保持架材料dDB额定承载极限转速额定承载极限转速CrCorGreaseOilCrCorGreaseOil71900C/AC102262.91.8690001090002.71.76600090000胶木/尼龙71901C/AC122463.22.262000940003.12.15500084000胶木/尼龙71902C/AC152874.83.452000790004.63.24900074000胶木/尼龙71903C/AC173075.13.849000740004.83.64400066000胶木/尼龙71904C/AC203797.45.839000590007.05.63700055000胶木/尼龙71905C/AC254297.66.533000490007.26.22900044000胶木/尼龙71906C/AC304798.07.629000440007.67.22500039000胶木/尼龙71907C/AC3555101110.9250003900010.410.31900033000胶木/尼龙71908C/AC4062121414.2190003300013.313.51700029000胶木/尼龙71909C/AC45681214.716.1170002900013.915.21600027000胶木/尼龙71910C/AC5072121921.2160002700017.920.11400023000胶木/尼龙71911C/AC55801323.727.4140002300022.4261300021000胶木/尼龙71912C/AC60851324.830.3130002100023.328.71200019000胶木/尼龙71913C/AC65901325.131.9120001900023.630.21100018000胶木/尼龙71914C/AC701001634.543.3110001800032.641.21000017000胶木/尼龙71915C/AC75105162545.610000170003343.2850015000胶木/尼龙71916C/AC801101635.547.890001600033.545.3800014000胶木/尼龙71917C/AC851201846.561.985001500043.858.6750013000胶木/尼龙71918C/AC901151847.264.880001500044.561.470002000胶木/尼龙71919C/AC951301847.967.880001400045.264.1700012000胶木/尼龙71920C/AC1001402060.484.475001300056.979.9700012000胶木/尼龙71921C/AC1051452061.488.270001200057.883.5650011000胶木/尼龙71922C/AC1101502062.391.965001100058.787600010000胶木/尼龙71924C/AC1201652273.7107.660001000069.5101.957009000胶木/尼龙71926C/AC1301802476.3117.15700900071.9110.950008000胶木/尼龙71928C/AC1401902478.9126.45000800074.4119.746007500胶木/尼龙71930C/AC15021028118.2175.146007500111.4165.840006500胶木/尼龙71932C/AC16022028123.3191.240006500116.5181.138006000胶木/尼龙71934C/AC17023028125.7200.038006000118.5189.433005300胶木/尼龙71936C/AC18025033159.7249.135005700150.6235.930005000胶木/尼龙71938C/AC19026033162.8260.833005300153.5247.028004600胶木/尼龙71940C/AC20028038198.4311.428004600187.1294.926004300胶木/尼龙71944C/AC22030038206.6341.126004300194.8323.022003800胶木/尼龙71948C/AC240320382253102300350021230022003300胶木/尼龙71952C/AC260360462814252100310026540020002900胶木/尼龙71956C/AC280380462914552000280027643019002700胶木/尼龙71960C/AC300420563716001500220035156014002100铜71964C/AC320440563776201400210035158513001900铜)
