3. The installation datum plane and bracket installing plane should be clean, grease, burr, paint and other foreign body should be wiped off.
Installation:
1. The screws in the installing plane should be fit with the mounting holes in the slewing bearing
2. The slewing bearing has a soft zone marked with an “s” on the upper surface, when installing the bearing, it is important to ensure that this area is placed in a non-load or infrequent load zone.
3. When the bearing is placed on the supporting frame work it is important to check the interface between these 2 surfaces. This check should be carried out with the insertion of feel gauges between the 2 surfaces. If a gap should exist then it is recommended to plane/resurface the effective area so as to remove the gap.
4. Install slewing bearing with high strength screws, and choose appropriate strength bolts. All bolts are required to be tightened evenly. The sequence of this tightening process is shown in Pic. Welding of bearing is not allowed, in the event of welding any adjacent parts, heat transfer shall be avoided so as to cause the bearing to become deformed or change the hardness.
5. After installation, the bearing should be rotated to check for smooth operation and any emission of unusual noise. If either of the aforementioned are noted, then the bearing should be adjusted to eliminate them. The teeth of the largest run-out are coated with green paint.

How does the design of a slewing ring contribute to efficient rotation and movement?
The design of a slewing ring plays a crucial role in facilitating efficient rotation and movement in mechanical systems. Several design features contribute to its functionality and performance. Here’s a detailed explanation of how the design of a slewing ring contributes to efficient rotation and movement:
- Structure and Load Distribution: Slewing rings are designed with a large diameter compared to their thickness. This structural design ensures optimal load distribution across the bearing, allowing it to support axial, radial, and moment loads efficiently. The arrangement of rolling elements within the raceways helps distribute the load evenly, reducing stress concentrations and minimizing friction during rotation.
- Low Friction and Smooth Rotation: The rolling elements, which can be balls or rollers, are precisely positioned within the raceways of the inner and outer rings. The design ensures that the rolling elements make contact with the raceways at specific angles, reducing friction and enabling smooth rotation. This low-friction design minimizes power loss, enhances energy efficiency, and contributes to the overall efficiency of the system.
- Gear Mechanism: In some slewing ring designs, a gear mechanism is integrated into the bearing. This allows the slewing ring to act as a rotational drive system, enabling controlled and precise movement. The gear teeth engage with external gears or pinions, providing a means to transmit torque and facilitating rotational motion. The gear mechanism in a slewing ring design contributes to efficient and synchronized rotation in applications where precise positioning or continuous rotation is required.
- Sealing and Lubrication: Slewing rings are designed with sealing systems to protect the internal components from contaminants and prevent lubricant leakage. The sealing systems help maintain the integrity of the bearing by keeping out dirt, dust, water, and other particles that could cause damage or premature wear. Proper lubrication is also crucial for efficient rotation and movement. The design of slewing rings often includes lubrication channels or grease fittings to ensure adequate lubricant supply to the rolling elements and raceways, reducing friction and promoting smooth operation.
- Materials and Durability: Slewing rings are typically made of high-quality materials such as alloy steels or specialty steels that offer excellent strength, durability, and corrosion resistance. The choice of materials and the design of the slewing ring take into account the specific application requirements, including factors such as load capacity, operating temperature, and environmental conditions. The design ensures that the slewing ring can withstand the anticipated loads, operating conditions, and service life requirements.
Overall, the design of a slewing ring is carefully engineered to maximize load-bearing capacity, minimize friction, enable smooth rotation, and ensure durability. By incorporating features such as optimized load distribution, low-friction rolling elements, gear mechanisms, sealing systems, and appropriate materials, slewing rings contribute to efficient rotation and movement in mechanical systems, enhancing the overall performance and reliability of the equipment.
