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 shor tworking.                                 
3.With grease lubrication, 60% of these limiting speed will apply.                        
4.The inner race will be supplied with single.
