Our rubber coupling spider is a premium, flexible insert designed as the core component for jaw-type couplings. This high-grade Polyurethane (PU) coupling spider excels in transmitting torque while effectively damping vibrations, absorbing shocks, and compensating for shaft misalignments. Ideal for heavy-duty applications in steel rolling, lifting, forging, and various machinery, it ensures smooth operation and protects your equipment from wear. With a high torque capacity (22.4~2500 Nm), exceptional temperature resistance (-40~100°C), and low wear rate, this coupling spider guarantees longevity and reliability. We offer custom sizes and colors (Red, Yellow) to meet your specific OEM requirements.

Product Features

• Premium PU Material: Manufactured from high-grade Polyurethane for outstanding elasticity, tear resistance, and long service life.

• Superior Vibration Damping: Effectively absorbs shocks and vibrations, protecting connected machinery components like bearings and shafts.

• High Torque Transmission: Robust design handles a wide torque range from 22.4 Nm to 2500 Nm for demanding applications.

• Extended Temperature Range: Reliable performance in both extreme cold and high-heat environments (-40°C to 100°C).

Detailed Description

The GR PU Elastic Spider is a critical consumable component for flexible shaft couplings. Acting as the flexible heart of the assembly, this rubber coupling spider transmits power while accommodating minor misalignments between connected shafts. Its high hardness (SHA98°) ensures it can withstand significant mechanical stress without deforming, making it a perfect fit for large-scale equipment in sectors like steel, lifting, and oilfield machinery. By choosing our coupling spider, you invest in reduced noise, lower maintenance costs, and enhanced protection for your entire drive train, ensuring uninterrupted operational efficiency.
