    We have re-engineered the traditional slewing ring by moving the gear teeth to the internal diameter, creating a self-contained, protected drive interface. This allows the motor or pinion to sit inside the rotation envelope, drastically reducing the overall system diameter. Combined with our advanced lightweight series construction—utilizing high-strength aluminum alloys for non-load-bearing rings and optimized steel geometries—we deliver a bearing that offers exceptional torque density in a fraction of the weight of standard units. As a forward-thinking Chinese manufacturer specializing in lightweight motion solutions, we help global engineers build agile, safe, and energy-efficient machines without compromising on durability.

Product Series Overview: Stealthy Strength in a Light Package

Our internal gear lightweight flange series is designed for applications where space is at a premium and the operating environment demands protection.
  • Protected Internal Gearing: The gear teeth are cut into the inner ring, shielding them from dust, chips, and physical contact. This eliminates the need for external gear covers, saving space and reducing maintenance.
  • Hybrid Lightweight Construction: We strategically use aerospace-grade aluminum alloys for the housing/flange components where possible, paired with hardened steel raceways. This hybrid approach reduces total weight by up to 45% compared to all-steel equivalents.
  • Integrated Mounting Flanges: Both inner and outer rings feature machined flanges with precise bolt patterns, allowing for direct, rigid mounting to robot arms, gantries, or medical frames without adapter plates.
  • High Torque-to-Weight Ratio: Despite the weight reduction, the internal gear design allows for larger pitch diameters within a compact outer envelope, maximizing leverage and torque transmission efficiency.


Key Features: Why Internal Gears Win in Compact Designs

Why specify an internal gear lightweight flange slewing bearing? The benefits extend far beyond just saving weight:
  1. Superior Debris and Impact Protection: With the gear teeth enclosed within the bearing assembly, the risk of damage from falling objects, flying chips, or accidental bumps is virtually eliminated. This is crucial for mobile robots and harsh factory floors.
  2. Compact System Envelope: By placing the drive mechanism inside the bearing, you reduce the overall radial footprint of your machine. This allows for tighter packing of multiple axes or operation in confined spaces.
  3. Enhanced Safety: The absence of exposed rotating gears reduces pinch points, making these bearings ideal for collaborative robots (cobots) and human-centric environments where safety is paramount.
  4. Reduced Inertia for Faster Cycling: The lightweight series design significantly lowers rotational mass. This means your servo motors can accelerate and decelerate faster, improving cycle times and reducing energy consumption.
  5. Cleaner Aesthetics and Maintenance: The smooth outer profile looks professional and is easier to clean. There are no external gear teeth to trap grease, dirt, or contaminants, simplifying hygiene protocols in food and medical applications.


Applications: Enabling Agile and Safe Automation

The internal gear lightweight flange slewing bearing is the preferred choice for industries prioritizing safety, compactness, and efficiency:
  • Collaborative Robots (Cobots): Ideal for base and joint rotations where exposed gears pose a safety risk. The smooth, enclosed design ensures safe human-robot interaction.
  • Automated Guided Vehicles (AGVs) & AMRs: Perfect for steering modules and turret rotations where low weight extends battery life and internal gearing protects against warehouse debris.
  • Portable Medical Devices: Used in surgical lights, imaging arms, and patient positioning tables where a clean, pinch-free profile and lightweight construction are essential for mobility and sterility.
  • Packaging and Pick-and-Place Systems: Enables high-speed indexing and rotation in tight packaging lines, with internal gears preventing product contamination from grease or metal shavings.
  • Semiconductor Handling Equipment: Provides clean-room compatible rotation with minimal particle generation, crucial for wafer handling and inspection tools.
  • Surveillance and Security Turrets: Allows for smooth, quiet pan/tilt operations in outdoor or rugged environments, with internal gears protected from weather and vandalism.
