Product Description

Light series four point contact ball slewing bearing in stock rks.21.0541
 

Product Description

Introduction:
Our Four-Point Contact Ball Bearings with External Gear and Inner Flange represent a pinnacle of integration in rotary motion design. This innovative unit uniquely combines a high-capacity ball bearing, a precision external gear for direct drive, and a convenient inner flange for easy mounting. It is engineered to simplify complex assemblies, save critical space, and provide reliable performance in compact, motorized applications.

Key Advantages:

• All-in-One Functional Integration: This single component seamlessly integrates three critical functions:

  • Bearing: Supports combined radial, axial, and moment loads.

  • Gear: Provides high-efficiency torque transmission via the external gear.

  • Mounting Interface: The inner flange allows for straightforward and secure shaft or structure attachment.

• Maximized Space Savings & Design Simplification: By eliminating the need for separate bearings, gears, and complex mounting arrangements, this design drastically reduces the overall system envelope, part count, and assembly time.

• High Load Capacity & Moment Stiffness: The four-point contact ball design enables the bearing to handle significant axial loads in both directions, radial loads, and tilting moments, ensuring stable and precise operation.

• Direct & Efficient Power Transmission: The precision-machined external gear allows a pinion to drive the unit directly, creating a compact, robust, and efficient drive system ideal for motorized applications.

• Simplified Assembly & Cost Reduction: The integrated design streamlines the manufacturing process, reduces logistical overhead, and lowers the total cost of ownership by minimizing components and labor.

Primary Applications:

• Compact Robotic Joints: Perfect for space-constrained joints in collaborative robots, robotic wrists, and actuators where a motor can be directly coupled.

• Precision Rotary Actuators: The ideal core component for building compact, high-performance rotary actuators used in automation and positioning systems.

• Advanced Machine Tools: Suitable for compact indexing heads, small rotary tables, and tool changers requiring integrated drive and support.

• Aerospace & Defense Mechanisms: Used in gimbal systems, sensor rotators, and antenna drives where a low-profile, lightweight, and integrated solution is critical.

• Medical Device Rotation: Applied in imaging equipment, surgical robot arms, and diagnostic devices demanding clean, compact, and precise rotation.
