What Defines the VU Series?

The VU series is characterized by its single-row four-point contact ball structure. Unlike standard radial bearings, the VU design allows a single row of balls to carry axial loads in both directions, as well as radial loads and tilting moments simultaneously.
Key structural advantages include:
  • Compact Axial Height: The single-row design significantly reduces the overall height of the assembly, making it ideal for tight installations.
  • Four-Point Contact Geometry: Each ball contacts the raceway at four distinct points, ensuring stable load distribution even under dynamic conditions.
  • Integrated Gear Options: Many models in the VU lineup come with external gear teeth cut directly into the outer ring, simplifying drive integration for rotary tables and positioning systems.
  • Separable Rings: The inner and outer rings are often designed with offset filling slots, allowing for higher ball complement and easier installation without the need for a full split ring.

Critical Features for Engineering Reliability

When sourcing slewing bearings from China, quality consistency is the primary concern for international buyers. Our VU series production adheres to rigorous metallurgical and machining standards:
  1. High-Purity Steel & Induction Hardening: We utilize premium alloy steel (typically 50Mn or 42CrMo) with precise induction hardening on the raceways. This ensures a hardness depth that resists spalling and wear, extending service life in abrasive environments.
  2. Precision Ground Raceways: Post-hardening grinding guarantees smooth rotation and low starting torque, critical for servo-driven applications like robotic arms and antenna positioning systems.
  3. Advanced Sealing Solutions: Standard rubber seals (NBR) protect against dust and moisture, while optional labyrinth seals or felt strips can be configured for extreme conditions found in construction or mining sites.
  4. Customizable Mounting: Threaded mounting holes are precision-drilled to match ISO standards or customer-specific drawings, ensuring direct interchangeability with existing designs.
