In modern industry, angular contact bearings are one of the most important accessories, especially in mechanical transmission. The angular contact bearings can withstand both radial and axial loads because of their structure characteristics. And they are widely used in many fields, such as heavy machine tools, the automotive industry, aerospace machinery, generation equipment, etc.
According to the different contact angles, angular contact bearings can be divided into three types: 15° contact angle (C type), 25° contact angle (AC type), and 40° contact angle (B Type). The design, performance characteristics, and application scenarios of these three types have differences.
The C-type angular contact bearing has a 15° contact angle, which is the smallest contact angle among the three types. The following are some of the 15° angular contact bearing’s information:
C-type angular contact bearings have a small contact angle, so they are very good in rotation speed. The 15° contact angle means that the sliding friction between the rolling element and raceway is less than 25° or 40° angular contact bearing, which results in reduced heat generation. As a result, this reduces friction and heat production can help to increase the bearings limiting speed.
C-type angular contact bearings will be helpful in high-speed and high-precision machine operations.
C-type angular contact bearings have low axial load-carrying capacity but possess high radial load-holding capability. It can be used in applications that support radial loads only with a small amount of axial force.
These C-type angular contact bearings have excellent performance, they are commonly used in high-speed rotation and precision industries such as aircraft engines, turbochargers, and precision machine tools, etc.
The AC-type angular contact bearings' contact angle is 25°. Among the three types, the 25° is a medium contact angle. The following are some of the 25° angular contact bearing’s information:
In the aspect of carrying axial loads, AC-type angular contact bearings have a better performance than C-type bearings. The 25° angular contact bearings have a great balance between radial and axial loads when machines and devices run. So the AC-type bearings are useful for high-speed rotation occasions that need to withstand large axial loads.
The rigidity and precision of AC-type angular contact bearings are excellent, so they can be applied to lots of environments. For machines that simultaneously need high speed and loads, AC-type bearings can play a good role.
The AC-type angular contact bearings can be used in gearboxes, textile machinery, pump equipment, drive shafts, etc. These mechanical machines usually require high speed and load capacity.
The B-type angular contact bearing' contact angle is 40°, which is the largest contact angle among the three types. The following are some of the 40° angular contact bearing's information:
The B-type angular contact bearing (40° contact angle bearing) is designed to carry large axial loads. The B-type bearings can withstand greater axial forces than the two others.
Due to the B-type bearings’ large contact angle, their speed performance is not as good as that of the C-type and AC-type bearings. This feature makes this type of bearing suit for some mechanical equipment that needs high axial load capacity but no speed requirements, such as heavy-duty machines, etc.
B-type angular contact bearings often apply in low-speed and high-load situations, such as heavy machine tools, screw pumps, construction machinery, and so on.
In practical engineering, which type of angular contact bearing should be chosen depends on the specific working conditions.
C-type (15°) angular contact bearings are the best choice for equipment that requires high-speed operation and does not bear axial load.
AC-type (25°) angular contact bearings are fitting in cases where the apparatus necessitates a certain axial load and rate of rotation.
At last, B-type angular contact bearings are used when the equipment requires high load and speed only is not required.
