Characteristics of CA Copper Insulated Spherical Roller Bearings

The characteristics of CA copper insulated self-aligning roller bearings are mainly reflected in the following aspects:

1、 Structural characteristics

Material of the cage: The cage is machined with brass as a whole. This cage not only has high strength, but also has certain self-lubricating properties, which can reduce friction and heat generation.

Roller design: The rollers are symmetrical and reinforced to withstand large loads. At the same time, the coordination between the rollers and the raceway has been optimized, which helps with lubrication and reduces wear.

Inner ring design: The inner ring does not have a middle stop edge, but there are two small stop edges on the end face. This design makes the bearing more flexible during installation and stress, and can adapt to certain installation errors and shaft deflection deformation.

2、 Performance characteristics

Strong bearing capacity: Due to the use of reinforced symmetrical rollers and optimized inner ring design, CA copper insulated self-aligning roller bearings can withstand large radial loads and bi-directional axial loads.

Good centering performance: The outer ring of the bearing has a common spherical raceway, and the inner ring has two raceways that are inclined at an angle to the bearing axis, which makes the bearing have good centering performance. When the shaft is subjected to force bending or installed with different concentricity, the bearing can still be used normally, and the alignment varies with the bearing size series. Generally, the allowable alignment angle is 1-2.5 degrees.

Good impact resistance: The brass cage has a certain plastic deformation ability, which can absorb a certain amount of impact energy and protect the bearing from damage.

Good lubrication performance: The self-lubricating performance of the brass cage and the optimized roller design make the bearing have low friction resistance, low heat generation, and good lubrication effect during operation.

3、 Application Fields

CA copper insulated self-aligning roller bearings are widely used in various mechanical equipment that needs to withstand heavy loads, impact loads, and vibration loads, such as steel plant equipment, cranes, port elevators, paper making machinery, etc. The working environment of these devices is often harsh, with high humidity, dust particles, high speed, and high temperature, as well as strong vibration impact, resulting in a very large workload. CA copper insulated self-aligning roller bearings, with their excellent performance characteristics, can meet the high requirements of these devices for bearings.

In summary, CA copper insulated self-aligning roller bearings have the characteristics of compact structure, strong load-bearing capacity, good self-aligning performance, good impact resistance, and good lubrication performance, and are indispensable key components in various heavy machinery equipment.
