Single-row crossed roller bearing incorporates two rings and is designed with compact construction, light weight, high precision, and small assembling clearance. The rollers are crossed one by one, enabling the slewing bearing to accommodate high axial, radial and tilting moment loads. Single-row crossed roller bearing is suitable for hoisting equipment and other engineering machinery.

single-row ball slewing bearing, also known as a single-row ball slewing ring or single-row ball turntable bearing, is a type of slewing bearing that consists of a single row of balls arranged between an inner and outer ring. This design allows for smooth rotational movement and the transmission of both axial and radial loads.
Single-row ball slewing bearings are commonly used in various applications where rotational movement is required, such as cranes, excavators, and industrial machinery. They provide a compact and lightweight solution while offering adequate load-carrying capacity.
These bearings are designed with raceways on both the inner and outer rings, which provide the paths for the balls to roll and transmit loads. The raceways are typically circular or slightly curved to allow for smooth and efficient rolling motion.
Single-row ball slewing bearings can handle both axial and radial loads, making them suitable for applications that require support for combined loads. They also have the advantage of low friction, which contributes to efficient operation and reduced power consumption.
When selecting a single-row ball slewing bearing, it is important to consider factors such as load capacity, rotational speed, mounting arrangement, and environmental conditions. The specific dimensions and load ratings of the bearing will depend on the application requirements.
