C45 Steel Bolt Spheres for Structural Connections - Customizable Sizes & Surface Treatments

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Load Balancing: Designed to stabilize machinery, equipment, and heavy-duty vehicles through precise weight distribution and counterweight applications.
  • Versatile Mounting: Central bore holes enable secure integration into structural frameworks via bolting or welding, supporting applications in construction, manufacturing, and transportation.

Key features

  • 1. Material Technology: Durable C45 Steel with Customizable Surface Treatments

  • With C45 steel construction and customizable surface treatments (e.g., anti-corrosion coatings), you can ensure long-lasting performance in harsh industrial environments. These spheres outperform standard cast iron components in durability and resistance to rust, extending equipment lifespan by up to 40%*.

  • 2. Interactive Design: Modular Spherical Shape with Central Mounting Holes

  • With a uniform spherical design and central precision-drilled holes, you can seamlessly integrate these bolt spheres into machinery for stable load balancing or structural connections. Their standardized mounting points simplify installation compared to irregularly shaped counterweights.

  • 3. Performance Parameters: Precision Engineering with Tight Tolerances

  • With diameters of 100mm, 200mm, and 300mm and ±1% tolerance, you can achieve precise structural alignment and load distribution. This accuracy reduces operational errors by 25% compared to loosely toleranced alternatives*.

  • 4. Scenario Solutions: Customizable Sizes for Diverse Industrial Applications

  • With customizable sizes and processing services (punching, welding, cutting), you can adapt these spheres to specific needs, such as stabilizing heavy machinery in construction or balancing loads in mining equipment. Their versatility surpasses rigid, non-modifiable components.

  • 5. Certification Standards: Compliance with GB Industrial Standards

  • With GB certification, you can ensure adherence to rigorous safety and quality benchmarks, guaranteeing reliability in critical applications. This certification provides a 30% higher safety margin than non-compliant products*.
