✅ 1. High-Performance Sealing for Hydraulic Cylinders
CFKS SPGO piston seals are specially engineered for double-acting hydraulic cylinders, using a two-part structure: a PTFE bronze Glyd ring for low friction and a NBR (or FKM) O-ring as an energizer to maintain sealing contact pressure. This design enables excellent performance in high-speed and high-pressure applications, such as in construction machinery, presses, and injection molding systems.

 

✅ 2. Low Friction and Long Service Life with PTFE Bronze
The PTFE bronze Glyd ring provides outstanding wear resistance and reduced friction, minimizing stick-slip effects and ensuring smooth piston movement even under extreme load variations. This makes the SPGO seal a preferred choice for high-frequency or continuous-duty hydraulic applications, especially in harsh environments where lubricant starvation may occur.

✅ 3. Customizable and Available for OEM Applications
CFKS offers SPGO seals in a variety of sizes and materials, customizable for OEM hydraulic cylinders or aftermarket needs. The seals are compatible with standard ISO grooves and operate reliably across a wide temperature range, making them ideal for mobile hydraulics, industrial automation, and heavy-duty equipment. Whether you require NBR, FKM, or custom PTFE blends, we provide precision solutions tailored to your application.

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.
