What's the Performance Features of BNAT805 Crossed Roller Bearing?
What's the Applications of the BNAT805 Crossed Roller Bearing?
The BNAT805 cross roller bearing can replace models such as CRBT805A and RAU8005. With dimensions of an inner diameter of 80mm, an outer diameter of 91mm, and a height of 5mm, both the inner and outer rings are integrated structures. Its unique design and performance make it suitable for a wide range of applications, as detailed below:
1. Robotics
The BNAT805 series features an ultra-thin structure with minimized axial and radial cross-sections (minimum section height of just 5mm), making it ideal for applications requiring lightweight and compact designs in rotating components. In various types of robots, this bearing meets the demands for high-precision rotation and compact joint designs, ensuring flexibility and stability in robot movements.
This type of bearing is mainly used in applications where either the inner or outer ring rotates with high precision requirements. In welding robots, precise rotation of the joints is critical to completing welding tasks accurately. The high-precision characteristics of the BNAT805 bearing ensure precise motion in the welding robot joints, improving welding quality.
2. Machine Tool Industry
In machine tool indexing mechanisms and CNC rotary tables, bearings must provide high precision and rigidity to ensure stability and accuracy during machining processes. The integrated structure, high rigidity, and high precision of the BNAT805 bearing meet the operational requirements of machine tool indexing and CNC rotary tables, enabling precise angular adjustments and positioning.
3. Inner Rotor DD Motors
Inner rotor DD motors require bearings that can handle both radial and axial loads while ensuring high-precision rotation. The BNAT805 bearing provides stable support for these motors, ensuring their efficient operation.
4. Other Fields
Alignment platforms typically require high-precision motion and positioning within limited space. The ultra-thin structure and high-precision characteristics of the BNAT805 bearing make it highly suitable for alignment platforms, meeting the platform's requirements for lightweight, compact design, and high precision.
