Двухрядные шариковые поворотные подшипники

Greater load capacity and better load distribution help reduce raceway and rolling element fatigue, thereby extending bearing life.

Due to its solid structure and excellent load-bearing capacity, double-row ball slewing bearings are particularly suitable for use in harsh working environments and where loads change frequently.

The contact angles of the two rows of raceways can be optimized for loads in different directions (axial force, radial force, overturning moment). For example, the arc angles of the upper and lower raceways are usually designed to be 90° to withstand large axial moments and overturning moments to the greatest extent.

Due to its strong load-bearing capacity, the double-row ball slewing bearing has a higher safety factor when carrying large loads, reducing the risk of failure.

The design of two rows of steel balls greatly increases the overall rigidity of the bearing, effectively resists deformation, and maintains the stability and precision of the mechanical system under heavy loads.

This is the most prominent advantage of the double-row ball slewing bearing. Compared with a single-row four-point contact ball slewing bearing of the same size, the double-row design can significantly increase the load-bearing capacity of axial, radial and especially overturning moments. This makes it very suitable for bearing heavy loads and harsh working conditions.
