1️⃣ Precision-Engineered GR 65 Coupling Spider

The CFKS Coupling Spider GR 65 is a high-quality elastic element designed for GR series jaw couplings. Made from premium polyurethane (PU) material, it provides excellent flexibility, durability, and resistance to oil, wear, and high temperatures. This GR 65 coupling spider ensures efficient torque transmission and superior vibration damping performance.

2️⃣ Reliable Power Transmission Performance

CFKS GR coupling spiders play a vital role in connecting motor and driven shafts, absorbing shock loads, reducing noise, and preventing misalignment damage. The GR 65 coupling spider is widely used in pumps, compressors, conveyors, and industrial machinery, helping maintain stable, low-maintenance operation across demanding environments.

3️⃣ Customizable and Durable Design

Available in multiple hardness options and sizes, CFKS coupling spiders are compatible with standard GR couplings from 19 to 90 series. The GR 65 coupling insert offers a balance of flexibility and strength, ensuring long service life even under continuous high-speed or heavy-load applications. Custom colors, hardness levels, and materials are also available.

Frequently Asked Questions (FAQ)

Why does my CFKS oil seal fail prematurely? Common causes and prevention tips2025-06-26T15:44:39+08:00

Premature oil seal failure can result from improper installation, poor shaft finish, incorrect material selection, or excessive pressure. To prevent this, ensure the shaft surface is smooth and within tolerance, use correct tools during installation, and choose seals made from materials compatible with your media and temperature.

How to correctly install a CFKS industrial oil seal to avoid leakage2025-06-26T16:04:32+08:00

Always clean the shaft and bore before installation. Use appropriate seal drivers to avoid deformation. Lubricate the lip before fitting to reduce friction during the first rotation. Ensure the seal is seated evenly and not tilted to avoid leaks.

What to do when your CFKS hydraulic seal is leaking under pressure2025-05-20T16:33:14+08:00

Check if the pressure exceeds the seal’s rated limit. Examine for wear, hardening, or improper installation. Replace the seal if damaged, and consider upgrading to a high-pressure CFKS seal variant. Also, verify that the housing and shaft are properly aligned.

How to choose the right CFKS oil seal for extreme operating environments2025-05-20T16:34:39+08:00

For high temperatures, aggressive chemicals, or abrasive environments, choose CFKS seals made of FKM, PTFE, or high-performance elastomers. Consider using seals with protective dust lips or metal casing. Our team can recommend the best fit for your application.
