轴承型号:2242材质：高碳铬滚动轴承钢（GCr15）内径(d):22mm外径(D):42mm装配高度(T):14.60mm内圈高度(B):14.40mm外圈高度(C):12mm轴承的安装和拆卸常识安装轴承时，可以根据其类型和尺寸，选择机械、加热或液压等方法时行。但在任何情况下，都不可以直接敲击轴承套圈、保持器、滚动体或者密封件。安装时对轴承施加的作用力，绝不可以通过滚动体从一个轴承套圈传递到另一个轴承套圈，否则可能会对滚道造成损坏。对于间隙配合的轴承圈，建议在配合面涂上一层薄薄的防蠕动腐蚀剂，以防止配合面之间产生摩擦腐蚀。BearingumbersDimensions(mm)WeightdDTBCRrKg11590/2015.87542.86214.28814.2889.5251.51.50.1LM11749/1017.46239.87813.84314.60510.6681.31.30.081LM11949/1019.0545.23715.49416.63712.0651.31.30.125A6075/A615719.0539.99212.01411.1539.5251.30.07M12649/1021.4350.00517.52618.28813.9701.31.30.169LM12748/1021.4345.23715.49416.63712.0651.31.30.121LM12749/1021.98645.23715.49416.63712.0651.31.30.120LM12749/1121.98645.97415.49416.63712.0651.31.30.123JLM22349/10224114.40014.40011.4000.80.80.0815101/24525.4006219.05020.63814.2880.81.30.3L44643/1025.40050.29214.22414.73210.6681.31.30.1315578/2025.40057.15017.46217.46213.4951.31.50.22M84548/1025.40057.15019.43119.43114.7321.51.50.24115103/24526.15762.00019.05020.63814.2880.81.315103S/24326.16261.91219.05019.93914.2880.82.015106/24526.98862.00019.05020.63814.2881.30.8L44649/1026.98850.29214.22414.73210.6683.51.30.12ST27492749151511.53.30.80.118320/28X2852161612.00.146TF28KW02G5SA285218.49816.01988/2228.57557.15019.84519.35515.8753.51.50.213M86647/1028.57564.29221.43321.43316.6701.51.50.348L45449/1029.00050.29214.22414.73210.6683.51.30.11332901329.00050.29214.22417.52010.6680.113
