Dynamic Torque Efficiency: ROTEX 24 & Rotex28 Flexible Spider Jaw Coupling

The ROTEX 24 and Rotex28 Series Flexible Spider Jaw Couplings (ROTEX Acoplamiento Flexible) are engineered to provide dependable, vibration-dampening power transmission across modern industrial drivetrains. Designed to connect motor shafts, gearboxes, and industrial pumps, these flexible couplings absorb heavy operational shocks, isolate mechanical resonance, and correct angular, parallel, and axial shaft misalignments. By introducing a resilient elastomeric spider insert between two precision interlocking jaw hubs, the ROTEX series ensures smooth, low-maintenance energy transfer without sacrificial wear on connected bearings.

Manufactured to elite industrial standards, the hubs feature robust structural composition utilizing high-strength S45C medium-carbon steel paired with advanced high-frequency induction quenching on the tooth tops. Enclosed in a lightweight, robust aluminum alloy die-casting housing, this design delivers exceptional torsional strength, low rotational inertia, and massive load thresholds—capable of sustaining rated torques up to 2000 N·m and operating speeds up to 5,000 RPM.

Core Product Advantages

• High-Frequency Quenched S45C Teeth: The critical torque-bearing jaw profiles are machined from S45C structural carbon steel with induction-hardened tooth tops, delivering premium fatigue resistance and anti-wear security under reversing loads.

• Premium Die-Cast Aluminum Housing: Wrapped in an advanced aluminum alloy die-cast shell that significantly lowers overall assembly weight, minimizes centrifugal stress, and ensures smooth rotational kinetics.

• Impressive 2000 N·m Rated Torque Curve: Heavy-duty architecture permits safe handling of severe start-stop cycles, high inertia, and extreme peak torque spikes without physical deformation.

• Secure Keyway & Set Screw Fastening: Formulated with a traditional dual-locking arrangement—utilizing finished keyways alongside high-tensile set screws—to guarantee positive mechanical lock and eradicate shaft slippage.

• Flexible Misalignment & Dampening Action: The curved jaw geometry compresses the central elastomeric cushion uniformly, actively protecting your motor components, spindles, and encoders from excessive vibration.

• Substantial Dimensional Accommodation: Standard inner hole/bore diameters span from 12mm up to 360mm, accompanied by an adaptable outer diameter matrix from 69mm up to 745mm to fit major machinery footprints.

• Direct Manufacturer OEM/ODM/OBM Sourcing: Backed by Apexcoupling’s state-of-the-art production facility in Dongguan, we provide complete engineering customization for bespoke bore tolerances, stepped shafts, non-standard lengths, and unique keyway sizes.
