Internal Gear Double Row Different Diameter Ball Slewing Bearing - High-Precision & Durable

Double Row Different Diameter Ball Slewing Bearing (Internal Gear)

Double row different diameter ball slewing bearings (internal gear) are specialized bearings designed for applications requiring high load capacity and precise rotational movement. They feature two rows of rolling elements with different diameters and an internal gear mechanism, allowing them to handle complex load conditions and offer smooth operation. These bearings include two rows of balls arranged to handle both axial and radial loads. The balls are of different diameters, which allows for a more compact design while maintaining high load-carrying capacity. The use of different diameter balls helps to distribute loads more evenly and reduce stress concentrations. This design is particularly useful in applications with varying load conditions. The bearing features an internal gear ring that meshes with an external pinion gear.

Product Details


Double Row Different Diameter Ball Slewing Bearing (Internal Gear) Introduction:

Double row volleyball turntable bearings are an integral component in the smooth rotation of the inner gear. This article aims to provide a comprehensive understanding of the inner gear in double row volleyball turntable bearings, highlighting its advantages and common applications.

1. What is the Inner Gear in Double Row Volleyball Turntable Bearings?

The inner gear in double row volleyball turntable bearings refers to the toothed component located at the center of the bearing. It is designed to facilitate the rotation of the bearing, allowing for efficient transfer of forces between the inner and outer rings

2. Advantages of the Inner Gear:

2.1 Enhanced Load Capacity:

The inner gear, with its teeth embedded in the bearing, provides improved load distribution. This enhancement enables the bearing to withstand higher loads and minimizes the risk of premature failure.

2.2 Increased Stability:

By ensuring a secure connection between the inner and outer rings, the inner gear enhances the stability of the turntable bearing. This feature is crucial for applications that require smooth and precise rotation, such as robotics, construction equipment, and turntable systems.

2.3 Improved Efficiency:

The toothed design of the inner gear allows for a greater number of contact points between the gears. This results in reduced friction and improved efficiency, contributing to longer service life and optimal performance of the turntable bearing.

3. Applications of Double Row Volleyball Turntable Bearings with Inner Gears:

3.1 Robotics and Automation:

In robotics and automation systems, double row volleyball turntable bearings with inner gears are used to support rotating platforms and ensure precise positioning. These bearings enable smooth movement with minimal friction, enhancing the overall performance of the systems.

3.2 Construction Machinery:

Double row volleyball turntable bearings with inner gears find applications in construction machinery, such as cranes and excavators. Their robust design and load-bearing capabilities make them ideal for withstanding heavy loads and harsh operating conditions.

3.3 Turntable Systems:

In the field of turntable systems, such as rotating stages in theaters and entertainment venues, double row volleyball turntable bearings with inner gears enable seamless rotation. Their ability to handle heavy loads while maintaining stability ensures smooth and reliable operation.
