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.
