1. Product Introduction & Applications
The CFKS VA Seal, also known as a V-Ring Seal, is a highly effective rotary shaft seal designed for axial sealing on rotating shafts. It is widely used in water pumps, electric motors, gearboxes, compressors, and hydraulic equipment. The flexible sealing lip ensures superior protection against contaminants such as dust, dirt, and water, preventing premature wear of internal components.

 

2. Material Options & Performance
This VA Seal is available in NBR (Nitrile Rubber) and FKM (Fluoroelastomer) materials. NBR VA Seals offer excellent resistance to oil, abrasion, and low temperatures, suitable for general industrial machinery and hydraulic systems. FKM VA Seals deliver outstanding high temperature and chemical resistance, making them the preferred choice for demanding applications with high rotational speeds and harsh environments.

3. Technical Features & Advantages
CFKS VA V-Ring Seal features a self-retaining, flexible design that securely fits around the shaft while maintaining a tight axial seal. It reduces friction, energy loss, and wear while providing reliable sealing in both dry and wet conditions. With strong resistance to dust, water, and oil leakage, this Rotary Shaft VA Seal ensures long service life in applications such as piston rod sealing, hydraulic equipment, pumps, fans, and industrial compressors.

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.
