Self-aligning roller bearing of CA structure, characterized by precision-machined brass cage, reinforced symmetrical rolling body,
Under normal circumstances, it can be used in common with CC structure design. Compared with the CC structure, the CA structure uses a high tensile strength brass cage. The cage itself has a certain self-lubricating property and allows a certain deformation. Under the current limitations of domestic mold process conditions, in the case of high noise requirements, the use of CA structure design will be better than CC type structure design. At the same time, due to the cage of the CA structure, under the condition of limited outer dimensions of the bearing, more internal space is occupied, so that the size and number of the rolling elements are limited, thereby reducing the bearing and further improving its radial load. The possibility of ability.
· Spherical roller bearing CC type
The spherical roller bearing of the CC structure is characterized by the use of a steel stamping cage, a reinforced symmetrical rolling body, and a movable intermediate spacer, which can be generally used in common with the CA structure design. Compared with the CA structure, the CC structure adopts high-quality carbon structural steel stamping parts, and the tensile strength of the cage is greatly improved. At the same time, the open CC structure design occupies less bearing internal space than the CA structure design. By increasing the number of rolling elements and changing the outer dimensions of the rolling elements, the radial bearing capacity of the bearing can be improved to some extent. Because the CC-type design uses a movable intermediate spacer, it can withstand greater axial load carrying capacity than the CA structural design. Both CA and CC type structural design are equivalent at the limit speed.
Since the CA structure uses brass as a raw material, the copper cage is formed by centrifugal casting and machining. Smelting in copper
During the process, a large amount of harmful gases and harmful metal elements are generated, which greatly damages the surrounding environment. As the world's awareness of environmental protection is increasing, CC structural design can better adapt to this development trend.
