Bearings for Screwdrivers: Types, Functions and Importance
Discover types of bearings used in screwdrivers, their functions, and why they are essential for smooth rotation, durability, and tool efficiency. Screw drivers—especially electric and micro motor screw drivers—are precision tools widely used in electronics assembly, automotive manufacturing, medical device production, and light industrial applications. While motors and gear systems often get the most attention, the smooth performance and durability of a screw driver depend heavily on a small but vital component: the bearing.
