Double-row angular contact ball bearings 双列向心推力滚珠轴承
Single-direction and double-direction angular contact thrust ball bearings (Figures 1.50 and 1.51) are used for machine tool spindles requiring rigid axial guidance.
单向和双向推力角接触球轴承（图1.50和1.51）都用机床主轴轴向刚性作为指导。
In this paper the relation between axial and radial clearance and free contact angle are determine through analysing double-row angular-contact ball bearings and double-row spherical roller bearings.
本文引用了法向游隙的概念，对双列向心球面球轴承和双列向心球面滚子轴承的游隙关系和初始接触角作了一些分析，确定了它们之间的相互关系。
DB combinations, DF combinations and four-point contact, double row angular contact ball bearings can withstand radial and bi-axial load.
DB组合，DF组合及四点接触、双列角接触球轴承可承受径向和双向轴向负荷。
