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、 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, the maximum allowable working themperrature is 120℃ in continuous working and 180℃ in short working.
3. With grease lubrication, 60% of these limiting speed will apply.
