Product Short Description

Hytrel GS Spider Coupling Rubber Insert for Industrial Flexible Jaw Couplings

The Apex Coupling GS Type Spider Insert is a high-performance flexible coupling element manufactured from imported Hytrel material. Designed for GS-type curved jaw couplings, it provides reliable torque transmission, vibration damping and misalignment compensation while offering excellent wear resistance, oil resistance and high-temperature performance up to 200°C.

Available in standard GS sizes and customizable dimensions, the spider insert is suitable for industrial machinery, motors, pumps, compressors, gearboxes and other power transmission equipment. OEM, ODM and custom production based on drawings or samples are supported.

Product Description

GS Type Hytrel Spider Coupling Rubber Insert

The GS Type Spider Coupling Rubber Insert is the flexible element installed between the two metal hubs of a curved jaw coupling. It acts as the elastic connection between the driving and driven shafts, allowing the coupling to transmit torque while reducing shock, vibration and the effects of shaft misalignment.

Apex Coupling manufactures GS-type spider inserts using imported Hytrel material, providing a combination of elasticity, mechanical strength, wear resistance and temperature resistance for demanding industrial applications.

Compared with ordinary rubber or standard polyurethane coupling spiders, Hytrel is particularly suitable for applications where the flexible element is exposed to oil, heat, mechanical stress and continuous operation.

Our GS spider inserts are available in multiple standard sizes, with OEM and ODM customization available for special dimensions, materials and performance requirements.

Key Features

Key Features of GS Hytrel Spider Coupling Rubber

1. Imported Hytrel Material

Made from high-performance imported Hytrel elastomer, the GS spider insert provides a balance of flexibility, toughness and mechanical durability for industrial power transmission.

2. Oil and Chemical Resistance

The Hytrel material offers excellent resistance to many industrial oils and chemicals, making the spider insert suitable for machinery operating in demanding industrial environments.

3. High Temperature Performance

The material can maintain stable performance at temperatures of up to 200°C, making it suitable for high-temperature machinery and power transmission applications.

4. Excellent Wear Resistance

The GS spider insert is designed for long-term mechanical contact with the coupling jaws. Its wear-resistant material helps extend replacement intervals and reduce equipment downtime.

5. Vibration and Shock Absorption

The flexible spider element absorbs torsional shock and vibration between the two coupling hubs, helping protect connected equipment such as motors, pumps, gearboxes and compressors.

6. Misalignment Compensation

The elastic spider allows the flexible jaw coupling to accommodate limited angular, parallel and axial shaft misalignment.

7. Low Maintenance

The spider is a replaceable elastomeric element. The flexible jaw coupling design requires no lubrication, helping simplify routine maintenance.

8. OEM & Custom Manufacturing

Apex Coupling supports OEM, ODM and OBM production, including custom dimensions, material selection and production according to customer drawings or samples.

Applications

Applications of GS Hytrel Spider Coupling Inserts

The GS spider coupling insert can be used in a wide range of industrial power transmission systems, including:

• Electric motors
• Industrial pumps
• Water pumps
• Air compressors
• Gearboxes
• Fans and blowers
• Conveyors
• Machine tools
• Industrial automation equipment
• Manufacturing machinery
• Steel and metal processing equipment
• Material handling equipment
• Construction machinery
• General mechanical drive systems

The flexible jaw coupling structure is widely used because the elastomeric spider can transmit torque while helping damp vibration and accommodate limited shaft misalignment.

How the GS Spider Coupling Works

How Does a GS Spider Coupling Work?

A GS flexible jaw coupling consists of three primary components:

Driving Hub → Hytrel Spider Insert → Driven Hub

The metal hubs contain curved jaws that engage with the lobes of the spider insert.

During operation:

1. The motor rotates the driving hub.
2. The driving jaws compress the Hytrel spider.
3. The spider transfers torque to the driven hub.
4. The elastomer absorbs torsional vibration and shock.
5. The flexible element allows limited shaft misalignment.

This simple three-piece design makes the coupling easy to install, inspect and maintain.
