    Frequently Asked Questions

    Q1: What is the expected service life of the MTBCC series coupling?

    When properly aligned and lubricated, the coupling is designed to operate for over 20,000 hours, typically lasting 3 to 5 years in standard drilling applications.

    Q2: What materials are used in the construction of these couplings?

    The couplings are primarily manufactured from high-strength alloy steel 42CrMo (equivalent to AISI 4140/4340) to ensure durability under heavy loads.

    Q3: Can these couplings handle extreme temperature environments?

    Yes, the MTBCC series is rated for a temperature range of -40°C to 120°C, making it suitable for diverse industrial climates.

    Q4: Do I need external splines for axial movement?

    No, the ball-cage universal coupling allows for significant axial displacement compensation internally, eliminating the need for external spline connections.

    Q5: What certifications or inspections are available for these products?

    We provide third-party witness and inspection reports from recognized bodies such as Bureau Veritas (BV), CCS, ABS, and SJS.

    Q6: What are the primary applications for the ball cage coupling?

    It is a key component for heavy-duty drive systems, including drilling rigs, mud pumps, rotary tables, and other high-torque transmission machinery.
