Double direction
1. Bear large axial load: Double-row thrust ball bearings can bear greater axial loads than single-row thrust ball bearings.
2. High speed: Double-row thrust ball bearings have higher speeds than other bearing types.
3. Low friction coefficient: Since double-row thrust ball bearings use ball bearings, their friction coefficient is lower.
4. Compact structure: Compared with other bearing types, double-row thrust ball bearings have a more compact structure and occupy less space.
5. Controllable positioning accuracy: The balls in double-row thrust ball bearings are not prone to problems such as ball eccentricity during movement, so they have higher positioning accuracy.
