What is Double-row Ball Slewing Ring Bearing?

Double-row Ball Slewing Ring Bearings are essential components of heavy machinery with rotating elements, such as excavators, cranes, and wind turbines. They consist of two concentric rings - inner and outer - which facilitate the smooth rotation of the equipment. Between these rings, two rows of spherical rolling elements (balls) are situated, separated by a spacer to reduce friction and provide enhanced load capacity.

Features of Double-row Ball Slewing Ring Bearing

Double-row Ball Slewing Ring Bearings have several distinct features:

1. Higher Load Capacity: Double-row design enables this bearing to support higher axial, radial, and tilting moment loads compared to single-row bearings.

2. Greater Stability: The double-row arrangement ensures stability during operation, even under demanding conditions.

3. Compact Design: While offering increased load capacity, these bearings maintain a relatively compact profile, making them suitable for various applications.

Purpose of Double-row Ball Slewing Ring Bearing

These bearings are commonly used in industries such as:

1. Heavy Machinery: Widely found in construction equipment like excavators and cranes, double-row ball slewing ring bearings facilitate the movement and rotation of heavy loads.
