Product Deep Dive

The shift towards ball-type slewing supports in robotics is driven by the need for higher speeds and lower friction. Unlike roller elements which can generate more heat and drag at high RPMs, our optimized ball geometry offers:
  • Four-Point Contact Efficiency: A single row of balls contacts the raceway at four points, allowing the bearing to simultaneously handle axial loads (from the arm's weight), radial loads (from lateral forces), and tilting moments (from off-center payloads). This eliminates the need for multiple bearing sets, drastically reducing the joint's axial height and overall weight.
  • Low Inertia Design: By utilizing a single row and optimizing the cage design, we significantly reduce the rotating mass. This allows robot servos to accelerate and decelerate faster, improving cycle times and energy efficiency—crucial metrics for high-speed industrial robots.
  • Smooth, Low-Friction Motion: The point contact of balls results in inherently lower starting and running torque compared to line-contact rollers. This ensures buttery-smooth motion, essential for collaborative robots (cobots) that interact safely with humans and require sensitive force feedback.


Key Features Engineered for Precision

Our robotic slewing bearings are built with features that address the specific pain points of automation engineers:
  1. Preloaded for Zero Backlash: We offer customized preload settings to achieve near-zero backlash. This is vital for applications requiring high repeatability, such as welding, dispensing, or assembly, where even a fraction of a millimeter of play can ruin product quality.
  2. Compact Thin-Section Profile: Our bearings feature an ultra-thin cross-section, allowing designers to create slimmer, more aesthetic robot arms without sacrificing structural integrity. This is particularly valuable for lightweight cobots and mobile manipulators.
  3. High Rigidity-to-Weight Ratio: Despite their light weight, the four-point contact geometry provides exceptional stiffness against moment loads, preventing deflection under payload and ensuring precise positioning.
  4. Integrated Sealing & Lubrication: Designed for cleanroom and food-grade environments, our seals effectively keep out dust and debris while retaining long-life synthetic grease. We also offer options for re-lubrication ports for continuous operation scenarios.
  5. Customizable Mounting & Gearing: We can integrate internal or external gear teeth directly into the ring for direct-drive applications, or customize bolt patterns to match popular robot flanges, simplifying your assembly process.


Strategic Applications in Automation

Our single-row four-point contact ball slewing supports are enabling breakthroughs across various robotic sectors:
  • Articulated Robot Arms: Serving as the primary rotation joint for axes J1, J2, and J3 in 6-axis robots, providing the range of motion and load capacity needed for heavy lifting and complex maneuvers.
  • Collaborative Robots (Cobots): The low friction and smooth motion make our bearings ideal for the sensitive joints of cobots used in assembly, packaging, and human-robot interaction zones.
  • SCARA Robots: Providing the high-speed rotational base for SCARA units used in electronics manufacturing and semiconductor handling.
  • Mobile Manipulators & AGVs: Enabling the rotating turret on autonomous mobile robots, allowing them to navigate and manipulate objects dynamically in warehouses and factories.
  • Medical & Surgical Robotics: Where precision and cleanliness are paramount, our low-particulate, smooth-operating bearings support the delicate movements of surgical arms and imaging devices.
  • Exoskeletons & Wearable Robotics: The lightweight nature of our single-row design is perfect for wearable tech, reducing user fatigue while supporting joint movement.
