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，在型号后加TN，允许工作温度：120℃连续，150℃临时，180℃短期。
3、 脂润滑时，极限转速为表列数值的60%。
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
themperrature is 120℃ in continuous working ,150℃ in temporary
working and 180℃ in short working.
3. With grease lubrication, 60% of these limiting speed will
apply.
