Disc / Laminae Non-API Couplings (RLDS BSB/ RLDS BWB Series)

Product Overview

The Disc / Laminae Non-API Couplings RLDS BSB/ RLDS BWB Series are high-performance, all-metal flexible couplings designed for precision torque transmission in critical industrial applications. These couplings utilize stainless steel laminae (disc packs) to transmit torque without the use of elastomeric elements, ensuring high torsional rigidity, zero backlash, and maintenance-free operation.

Engineered for reliability and accuracy, RLM & RLMK Series couplings are ideal for applications requiring high speed, precise alignment, and consistent performance, making them suitable for modern industrial machinery and rotating equipment.

Key Features & Benefits

  • All-Metal Construction

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

  • Zero Backlash

    Provides precise torque transmission with no play or hysteresis, ideal for high-precision applications.

  • High Torsional Rigidity

    Ensures accurate motion control and efficient power transmission.

  • Maintenance-Free Operation

    No lubrication required, reducing operational costs and maintenance effort.

  • High Misalignment Capability

    Disc packs accommodate angular, parallel, and axial misalignment without compromising performance.

  • Suitable for High-Speed Applications

    Balanced design enables smooth operation at high rotational speeds.

  • Corrosion Resistant

    Disc packs typically made from stainless steel, offering excellent resistance to corrosion.

Construction & Working Principle

Components:
Metallic Hubs:
• Precision-machined hubs made from high-strength steel

Disc Pack (Laminae Set):
• Multiple thin stainless steel discs assembled in a pack for flexibility and strength

Spacer (if applicable):
• Provides shaft separation and facilitates maintenance

Fastening Bolts & Bushings:
• High-strength fasteners ensure secure assembly and load distribution

Working Principle

Torque is transmitted through the disc pack, which flexes to accommodate misalignment while maintaining torsional rigidity. The laminae deform elastically under load, ensuring smooth power transmission without wear or backlash.
