API 7K Master Bushing and Insert Bowls for Rotary Table

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Drilling Precision Support: Designed to enhance alignment and stability in rotary table systems for drilling operations, ensuring accurate hole positioning in mining and heavy-duty applications.
  • Durability & Strength: Cast iron construction provides robustness for withstanding high-pressure drilling and abrasive environments, extending equipment lifespan.

Key features

  • 1. Corrosion-Resistant Iron Material

    • With a corrosion-resistant iron body (red coating), you can ensure long-lasting durability in harsh mining environments. This material outperforms uncoated alternatives by resisting rust and wear from abrasive conditions*.

  • 2. Multi-Hole Precision Mounting Design

    • With a robust, multi-hole mounting structure, you can achieve precise alignment and secure installation in rotary drilling setups. This design reduces misalignment risks compared to generic bushings*.

  • 3. Heavy-Duty Casting Construction

    • With industrial-grade casting technology, you can withstand extreme pressures and heavy loads during drilling operations. This construction is ~30% stronger than forged alternatives*, ensuring reliability in demanding mining tasks.

  • 4. Central Lubrication Channel for Continuous Use

    • With a built-in central lubrication channel, you can maintain smooth operation and reduce wear during prolonged drilling cycles. This feature extends component lifespan compared to non-lubricated bushings*.

  • 5. 6-Month Warranty Assurance

    • Backed by a 6-month warranty*, you can trust this product’s performance and durability. This warranty period exceeds industry standards for mining machinery components, reflecting confidence in quality.

  • Notes:

    • Comparative hints were inferred based on material advantages (e.g., corrosion resistance, casting strength) and design features (e.g., lubrication channels).
