Disc / Laminae API Couplings (REM & RSK Series)

Product Overview

The Disc / Laminae API Couplings – REM & RSK Series are high-performance, all-metal flexible couplings designed to meet the stringent requirements of API standards for critical rotating equipment. These couplings utilize stainless steel disc packs (laminae) to deliver precise, backlash-free torque transmission with exceptional reliability in demanding environments.

Engineered for high-speed, high-power, and critical applications, REM & RSK Series couplings are widely used in industries such as oil & gas, petrochemicals, and power generation, where performance, safety, and compliance are essential.

Key Features & Benefits

  • API Compliant Design

    Designed in accordance with relevant API standards (such as API 610 / API 671 where applicable) for critical rotating equipment.

  • All-Metal Construction

    No elastomeric components, ensuring long service life, high temperature resistance, and consistent performance.

  • Zero Backlash

    Provides precise torque transmission without play, making it ideal for high-speed and precision-driven systems.

  • High Torsional Rigidity

    Maintains accurate shaft positioning and efficient power transmission.

  • Maintenance-Free Operation

    No lubrication required, reducing maintenance costs and downtime.

  • High Misalignment Capability

    Disc packs accommodate angular, parallel, and axial misalignment, including thermal expansion.

  • High-Speed Capability

    Precision-balanced design ensures smooth operation at very high rotational speeds.

  • Corrosion & Fatigue Resistance

    High-grade stainless-steel laminae provide excellent resistance to corrosion and cyclic loading.

Construction & Working Principle

Advantages
• High precision and zero backlash performance
• No wear components, ensuring long service life
• Suitable for high-speed and high-temperature applications
• Maintenance-free with no lubrication required
• Ideal for critical and precision-driven systems

Typical Applications
Disc / Laminae Couplings (RLM & RLMK Series) are widely used in:
• Pumps and compressors
• Turbines and generators
• High-speed rotating equipment
• Process and chemical industries
• Precision machinery and automation systems

These couplings are ideal for applications requiring accuracy, reliability, and maintenance-free operation.

Working Principle

Torque is transmitted through the disc pack assemblies, which flex elastically to accommodate misalignment while maintaining torsional rigidity. The absence of wear components ensures consistent performance and long operational life, even under high-speed and high-load conditions.
