Combined needle bearings are single directional positioning bearings or the positioning bearings with minimum radically sectional height.

If the centripetal needle bearings are used with thrust ball bearings or cylindrical roller bearings in combination, the applicable range will be greatly expanded. The combined needle bearings are mainly used in transmission engineering and tooling machines such as the bearings in the main shaft of adrill press, drill sleeve, positioning central shaft, worm, spanner teeth head and so on.
