More comprehensive load - bearing capacity
Ordinary radial spherical plain bearings mainly focus on withstanding radial loads. Although they can also bear a certain amount of axial load, their axial load - bearing capacity is limited. In contrast, angular contact spherical plain bearings can simultaneously withstand relatively large radial and axial loads, as well as a certain overturning moment. For example, in the transmission components of some aero - engines, which need to handle forces from multiple directions simultaneously, angular contact spherical plain bearings can better meet the requirements of such complex - load working conditions.
Adaptability to angular deviation conditions
Angular contact spherical plain bearings have better adaptability to the angular deviation between the shaft and the bearing housing. In some mechanical equipment, due to installation errors, deformation during operation, etc., a certain angular deviation may occur between the shaft and the bearing housing. Angular contact spherical plain bearings can operate normally under such circumstances, ensuring the stability and reliability of the equipment. However, when the angular deviation is relatively large, ordinary radial spherical plain bearings may experience problems such as excessive local stress and intensified wear.
Relatively lower requirements for sealing and lubrication
Tapered roller bearings require relatively strict sealing and lubrication conditions during operation to prevent impurities such as dust and moisture from entering the bearing interior and affecting its normal operation. Due to their own structural characteristics, angular contact spherical plain bearings have relatively lower requirements for sealing and lubrication. In some harsh working environments, such as places with high dust and humidity, angular contact spherical plain bearings can adapt better, reducing maintenance costs and workload.
Compact structure
The structure of angular contact spherical plain bearings is relatively compact, occupying less space. In some equipment with high space requirements, such as aerospace equipment and precision instruments, angular contact spherical plain bearings can provide effective support and transmission within a limited space, meeting the design requirements of the equipment. In contrast, the structure of tapered roller bearings is relatively large and may not be very suitable in space - constrained situations.
