With Outer Cover Thrust Ball Bearing

Thrust ball bearings with cover: double guarantee of axial load bearing and protectionIn harsh environments such as dust and water vapor, shrouded thrust ball bearings rely on the integrated design of "loading + protection" to become a key component that takes into account both axial load transmission and contaminant isolation. They are widely used in medium and low-speed equipment that require cleanliness and sealing.From a structural point of view, it adds a **metal or engineering plastic outer cover** to the traditional thrust ball bearing (shaft ring, seat ring, steel ball-cage assembly). The outer cover is connected to the seat ring or shaft ring through buckles, interference fits, etc., forming a closed or semi-closed space that completely wraps the steel balls and raceways. According to different load-bearing directions, they can be divided into "one-way thrust ball bearings with a cover" and "two-way thrust ball bearings with a cover". The former contains 1 shaft ring + 1 seat…
