What is Robot Slewing Bearings?

Robot slewing bearings, also known as turntable bearings, are oversized rotational bearings that manage complex load combinations, such as axial, radial, and moment loads, while providing smooth and precise rotation. They are essential in various robotic applications such as robotic arms and rotary tables, maintaining accurate positioning and enhancing overall system performance.

Thorough Analysis of Robot Slewing Bearing Types

Robot slewing bearings can be classified based on their construction, design features, and specific application requirements. Common types include:

Single-row ball slewing bearings: These bearings feature a simple design suitable for smaller robotic applications requiring high precision and cost-effectiveness. They handle axial, radial loads, and tilting moments simultaneously, making them versatile for a wide range of applications. Single-row ball slewing bearings can be designed with various gear tooth options, including internal, external, or no gearing, depending on the system’s requirements.
Double-row ball slewing bearings: Comprising two rows of ball bearings, these bearings offer an enhanced load-carrying capacity and torque resistance suitable for larger robotic systems demanding stable performance in various operating conditions. Double-row ball slewing bearings are typically used in situations requiring high precision, load and vibration resistance.
Crossed roller slewing bearings: These bearings consist of cylindrical rollers arranged perpendicularly to each other and spaced with separators, providing a compact and rigid bearing capable of handling complex loads. Crossed roller slewing bearings are ideal for robotic systems with limited space and high precision requirements.
Three-row roller slewing bearings: Featuring three rows of rollers, these bearings provide the highest load-carrying capacity and stiffness among all types of slewing bearings. They are suitable for heavy-duty robotic applications where high loads, precision, and extended service life are essential factors. These bearings are typically used in large-scale robotics systems demanding maximum performance and durability under intense operating conditions.
