Slewing bearings, often referred to as slewing rings or turntable bearings, are critical components in heavy-duty machinery and equipment, playing a pivotal role in the smooth and efficient rotation of large, heavy loads. These bearings are essential in a variety of industries, including construction, mining, renewable energy, and manufacturing, where they are utilized in applications such as cranes, excavators, wind turbines, and industrial machinery. At JHB Bearing, we specialize in delivering high-quality slewing bearings designed to meet the demanding requirements of these applications.
Slewing bearings are large-sized bearings capable of accommodating axial, radial, and moment loads, either individually or in combination. They consist of an inner ring and an outer ring, one of which usually incorporates a gear. This configuration allows the bearing to support heavy loads while enabling rotational movement around a fixed axis.
Single Row Ball Slewing Bearings: Primarily used in applications with lower load capacities and where space is a constraint. These bearings are suitable for light to medium-duty operations.
Double Row Ball Slewing Bearings: Designed for applications requiring higher load capacities and enhanced stability. These bearings are ideal for medium to heavy-duty operations.
Three Row Roller Slewing Bearings: Known for their high load-carrying capacity and rigidity, making them suitable for extremely heavy-duty applications such as large cranes and mining equipment.
Crossed Roller Slewing Bearings: These bearings offer high precision and load capacity, perfect for applications requiring precise movement and positioning, such as robotics and medical equipment.
High Load Capacity: Slewing bearings are designed to handle immense axial, radial, and moment loads, making them indispensable in heavy-duty applications.
Versatility: With multiple designs available, slewing bearings can be tailored to specific application requirements, ensuring optimal performance and longevity.
Precision and Stability: The robust construction and advanced engineering of slewing bearings ensure precise movement and exceptional stability, even under the most demanding conditions.
