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, 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.
