说明：

1.表中所列基本额定载荷、极限转速和重量，仅供选择参考用。

2.轴承的唇密封，允许工作温度：120℃连续。

3.脂润滑时，极限转速为表列数值的60%。

Note:

1.These load, speed and mass is reference of choice only.

2.If the cages are plastics,syffix"TN" is added to the bearing No.,the maximum allowable

working themperrature is +120℃ in continuous working and 180℃ in short time working.

3.With grease lubrication, 60% of these limiting speed will apply.
