EPDM SG 100 Rubber Spider Coupling

Saigoma’s Rubber Spider Couplings are engineered to absorb vibration and minimize shock between coupling components. With excellent anti-torsional properties and superior tensile strength, these rubber spiders deliver outstanding durability and long service life, even under demanding operational conditions.

Rubber Spider Couplings - Selection Guide

Selecting the correct rubber spider coupling is critical for ensuring the optimal performance, reliability, and longevity of your mechanical systems. Below are key considerations and guidelines to help you choose the right coupling for your needs.

1. Application Type

Vibration Absorption: If your application involves high levels of vibration, ensure the rubber spider coupling you select can absorb and dampen shock effectively. Saigoma rubber spiders are ideal for absorbing vibrations between rotating machinery and drive components.

Torque Transmission: For applications requiring efficient torque transmission, choose a rubber spider coupling with high tensile strength and anti-torsional properties.

2. Operating Temperature Range

Temperature Considerations: Rubber spiders have a specific operating temperature range. Saigoma’s couplings are designed to perform within a temperature range of 100°C to 200°C. Exceeding this range can cause material degradation, reducing performance and lifespan.

• For applications requiring higher temperature tolerance, ensure the selected spider coupling material is rated for the desired operating range.

3. Material Compatibility

Rubber Composition: The material of the rubber spider is crucial for durability. Choose from various materials based on the operating environment:

EPDM (Ethylene Propylene Diene Monomer): Best for environments with high humidity, ozone, and weather exposure.

• NR (Natural Rubber): Offers excellent resilience and flexibility.

• CR (Chloroprene Rubber / Neoprene): Resistant to oils, greases, and chemicals, making it ideal for harsh industrial conditions.

4. Size and Fit

Correct Sizing: The rubber spider coupling must fit precisely between the coupling components. Saigoma’s spider couplings come in different sizes, such as:

1. SG100

2. SG110

3. SG150

4. SG190

Ensure that the selected size matches the inner diameter of the coupling and the specific gap to be filled. Incorrect sizing can lead to reduced performance, premature wear, or even failure of the coupling.

5. Torque and Load Requirements

Torque Rating: Match the coupling size and material to the torque requirements of your system. A rubber spider coupling should be selected based on the maximum torque expected in your application. Saigoma rubber spiders are designed to handle significant torque loads without compromising their anti-torsional properties.

Load Variability: If your system experiences fluctuating or shock loads, consider a more resilient spider coupling with enhanced vibration dampening properties.

6. Durability and Service Life

Long-Term Use: Consider the long-term service life and durability of the coupling. Saigoma rubber spiders are designed to provide long-lasting performance in demanding environments, with resistance to aging, cracking, and chemical degradation.

Maintenance Intervals: Regular inspection and replacement may be necessary based on the operating environment, but selecting the right spider coupling will extend service intervals.

7. Specific Industry Requirements

Manufacturing and Heavy Machinery: For industrial applications with high-speed or heavy-duty machinery, rubber spider couplings with high tensile strength and vibration dampening are essential to ensure system stability.

Automotive or Transport: In automotive and transport systems, rubber spiders help reduce noise and vibrations in drivetrain components.

8. Environmental Considerations

Chemical Exposure: If your equipment operates in an environment where it may come into contact with chemicals, oils, or solvents, selecting a more chemical-resistant material (like CR or neoprene) will provide better durability and performance.

Corrosive Environments: For environments with high humidity, ozone, or UV exposure, EPDM

rubber spiders offer superior resistance to environmental degradation.
