NSK軸承NSK推力角接觸球軸承

推力角接觸球軸承:雙向推力角接觸球軸承,是作為機床主軸用而特別設(shè)計的高精度軸承,可以承受兩個方向的軸向負(fù)荷.這種軸承的變型品種很多，應(yīng)用很廣，常制成帶15°、25°和40°接觸角三種系列，接觸角愈大，其軸向負(fù)荷能力愈高，但在高速時宜采用小接觸角為宜。舉列型號：25BNR19S25BNR19H25BNR19X25BER19S25BER19H25BER19X30BNR19S30BNR19H30BNR19X30BER19S30BER19H30BER19X55BNR19S55BNR19H55BNR19X55BER19S55BER19H55BER19X60BNR19S60BNR19H60BNR19X60BER19S60BER19H60BER19X35BNR19S35BNR19H35BNR19X35BER19S35BER19H35BER19X40BNR19S65BNR19S65BNR19H65BNR19X65BER19S65BER19H65BER19X40BNR19H40BNR19X40BER19S40BER19H40BER19X45BNR19S45BNR19H45BNR19X45BER19S45BER19H45BER19X50BNR19S50BNR19H50BNR19X50BER19S50BER19H50BER19X70BNR19S70BNR19H70BNR19X30BNR10S30BNR10H30BNR10X30BER10S30BER10H30BER10X35BNR10S55BNR10S55BNR10H55BNR10X55BER。 詳細(xì)介紹>>
