The CFKS UN Hydraulic Oil Seal 45*5*38 is a high-performance PU piston sealing ring designed for hydraulic cylinders. Made from premium polyurethane (PU), this UN Oil Seal ensures outstanding resistance to pressure, wear, and extrusion. It provides reliable sealing for reciprocating hydraulic motion, effectively preventing leakage and contamination in cylinder systems.

 

This UN Type Hydraulic Oil Seal features excellent mechanical strength and elasticity, maintaining stability even under high working loads. The PU material ensures long-lasting durability, superior friction resistance, and compatibility with hydraulic fluids. Its optimized lip structure improves sealing efficiency and reduces energy loss, making it ideal for hydraulic pistons and cylinders used in excavators, loaders, and industrial machinery.

CFKS UN Oil Seals are widely applied in hydraulic cylinders, pneumatic systems, and industrial equipment. They provide effective sealing for reciprocating pistons, helping extend component lifespan and enhance operational reliability. With precise dimensions (45*53*8), these seals deliver exceptional performance in demanding construction and heavy-duty hydraulic environments.

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.
