What is the significance of spherical roller bearings?

Spherical roller bearings have double row rollers, the outer ring has a common spherical raceway and the inner ring has two raceways inclined diagonally to the bearing axis. This sophisticated design makes it self-aligning and thus less prone to error or shaft bending due to the angle of the shaft to the housing.

What are the design features of spherical roller bearings?

The spherical roller bearing has two rows of symmetrical spherical rollers, the outer ring has a common spherical raceway, and the inner ring has two raceways inclined at an angle to the bearing axis, which has good self-alignment performance. The bearing can still be Used normally when it is installed bent or misaligned. The orientation varies with the bearing size range. In general, the permissible alignment angle is 1 to 2.5 degrees. The outer bearing can also accommodate the axial load acting in both directions and has good performance shock resistance. In general, the permissible working speed of the spherical roller bearing is low.

What types of spherical roller bearings are there?

Spherical roller bearings are divided into two different structures: symmetrical spherical rollers and asymmetrical spherical rollers according to the cross-sectional shape of the rollers. Asymmetrical spherical roller bearings are early products, mainly for maintenance services of main motor, newly designed symmetrical spherical roller of main motor Bearing bearings are currently rarely used The internal structure has been extensively improved, Designed and optimized Compared with the spherical roller bearings of early production, it can withstand greater axial loads The operating temperature of this bearing is lower, therefore it is lower can meet the requirements of higher speed. Depending on whether the inner ring has ribs or not and the cage is used, it can be divided into spherical roller bearings type C and CA. The type C bearing is not characterized by an inner ring The ribs and the steel stamping cage are adopted, and the characteristics of the CA bearings are that on both sides there are ribs s of the inner ring and a solid car cage.

What is the cause of cracks in spherical roller bearings?

Through macroscopic and microscopic analysis, it can be seen that the rolling deformation marks on the surface of the annular raceway of the inner spherical roller bearing are prestressed in the direction of the boards, the bearing running surface is burnt, the surface of the ring has cracks, and the surface of the inner ring and roller are both made of plastic, in particular the plastic deformation zone of the inner ring has a large number of small cracks. The above phenomenon shows that the bearing is deteriorated due to the burning of the working surface. which leads to crack failure, and it can also be determined that the bearing failure mode is thermal crack formation.

Considering that different types of spherical roller bearings have different functions in different fields, we should choose the excavator that suits us according to our actual needs. SHANDONG CHIK BEARING CO., LTD bearing products cover a full range. Here you will find a spherical roller bearing that suits you.
