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. For sealed roller followers, the maximum allowable working themperrature is +120℃(in continuous working).
3. With grease lubrication, 60% of these limiting speed will apply.
