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%。

4.内圈须单独定货。

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.

4.The inner race will be supplied with single.
