Performance Features
Ultra-Thin Profile: Minimized axial and radial dimensions for compact, space-saving applications.
High Precision: Ensures accurate rotation, ideal for robotics and precision machinery.
Lightweight: Reduces overall weight, perfect for robotic joints and portable devices.
Versatile Load Capacity: Handles radial, axial, and moment loads efficiently.
Integral Structure: Single-piece inner and outer rings enhance rigidity and stability.
Applications
The application areas of the BNAT105 bearing are primarily concentrated in scenarios that demand high precision, lightweight design, and compact structure. These include the following fields:
1. Robotics
Collaborative Robots: Suitable for rotational support in joint sections, as its ultra-thin design (height of only 5mm) meets the requirements for lightweight and compact structures.
Service Robots: Such as logistics robots, cleaning robots, and other equipment with frequently rotating parts (e.g., heads, robotic arms).
Specialized Robots: Including firefighting robots, underwater robots, and other special-environment operation equipment, requiring high rigidity and stability.
2. Precision Industrial Equipment
CNC Machines: Used in indexing mechanisms and rotary tables for high-precision rotating components, replacing traditional bearings to improve equipment response speed.
Alignment Platforms: Such as precision positioning stages in semiconductor manufacturing, requiring minimal section size and high rotational accuracy.
3. Medical and Scientific Research Equipment
Surgical Robots: Provides precise rotational support for joints, ensuring stable performance in sterile environments.
Medical Devices: Such as rotating components in imaging equipment, requiring low friction and long service life.
4. Radar and Optical Equipment
Mobile Radar Vehicles: Supports rotating antenna bases, requiring vibration resistance and high reliability.
Optical Instruments: Such as rotating platforms in telescopes and laser positioning systems, demanding low backlash and high rigidity.
5. Other Industrial Applications
Hollow Rotary Platforms: Supports inner rotors of direct-drive motors (DD motors), requiring an extremely thin section to save space.
Harmonic Reducers: Precision transmission components in robotic joints, relying on the bearing's high load-carrying capacity.
