Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Flexible Shaft Connection: Designed to connect and transmit power between rotating shafts while absorbing shocks and vibrations, thanks to its rubber and steel composite construction.
  • Precision Alignment: The spider-jaw structure with radial slots and projections ensures stable alignment and smooth movement in dynamic applications.

Key features

  • 1. Durable Material Technology

    • With a corrosion-resistant steel body and high-performance rubber jaws, the ML Rotex Spider ensures robust durability and shock absorption in harsh industrial environments. The rubber material effectively dampens vibrations, extending equipment lifespan by up to 25%* compared to rigid couplings.

  • 2. Spider-Jaw Interactive Design

    • With an ergonomic spider-jaw structure, this coupling enables precise alignment between shafts and simplifies installation. Its radial slots and flexible rubber segments reduce alignment errors by 40%* compared to traditional rigid couplings, ensuring smooth operation in complex machinery.

  • 3. High-Performance Flexibility

    • Offering a torsional stiffness of up to 150 Nm and a misalignment tolerance of 1.5°, the flexible design handles heavy loads and frequent vibrations. This makes it ideal for applications like robotics and conveyor systems, outperforming standard couplings in dynamic environments.

  • 4. Versatile Scenario Solutions

    • Designed for continuous industrial use, the ML Rotex Spider accommodates shaft misalignment and thermal expansion, ensuring reliable performance in high-stress scenarios such as automotive assembly lines or HVAC systems. Its compact size also suits space-constrained machinery.

  • 5. RoHS Compliance for Sustainability

    • Certified to RoHS standards, the coupling uses eco-friendly materials free of hazardous substances. This aligns with global environmental regulations and supports sustainable manufacturing practices for industries prioritizing compliance and safety.
