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、 轴承的保持架如由塑料制成，允许工作温度：120℃连续，180℃短期。

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 made of plastics,suffix "TN" is added to the bearing No., the maximum allowable working temperature is 120℃ in continuous working and 180℃ in short time working.

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