The radial dimension of the rolling bearing is larger

With the development of enterprises, the use of bearings has become more and more common. Let's get to know rolling bearings and increase knowledge.

      Compared with sliding bearings, rolling bearings have larger radial dimensions, poorer damping ability, low service life at high speeds, and greater noise. A radial bearing in a rolling bearing is usually composed of an inner ring, an outer ring, rolling elements, and a rolling element holder 4 partially.

      The inner ring is tightly sleeved on the journal and rotates with the shaft, and the outer ring is installed in the bearing seat hole. Raceways are formed on both the outer circumference of the inner ring and the inner circumference of the outer ring. When the inner and outer rings rotate relatively, the rolling elements roll on the raceways of the inner and outer rings. They are separated by a holding frame to prevent mutual friction.

      Thrust bearings are divided into two parts: tight ring and live ring. The tight ring and the shaft sleeve are tight, and the live ring is supported on the bearing seat. Rings and rolling elements are usually made of rolling bearing steel with high strength and good wear resistance, and the surface hardness after quenching should reach HRC60-65. The holding frame is mostly made of mild steel stamping, and can also be made of copper alloy laminated bakelite or plastic.

      After a brief introduction by the editor, everyone should have an understanding of rolling bearings.
