CFKS Combi Oil Seal 45*60*16/17 Multi-lip Rotary Cassette Seal for Heavy Duty Machinery

The CFKS  45 *60 *16/17 Steel Case Rubber Combi Dust Seal is an extreme-duty rotary boundary component engineered for the most punishing agricultural and construction axle applications. By housing a primary hydrodynamic fluid lip and a massive secondary dirt-deflection labyrinth within an exposed, high-tensile steel case, this combined oil seal provides absolute isolation for expensive axle bearings against deep mud, submerged water crossings, and abrasive crop debris.

  • Exposed Steel Outer Case: The rigid metal casing guarantees maximum radial interference, preventing the seal from backing out or spinning in the housing under severe torsional vibration and shock loads.

  • Unified Combi-Architecture: Replaces traditional multi-seal setups by integrating oil retention and heavy-duty environmental exclusion into a single, precision 14.6mm deep unit.

  • Optimized Shaft Tracking: The highly flexible inner elastomeric matrix maintains a perfect hydrodynamic film on the 37mm rotating shaft, even under conditions of high dynamic runout.

Unlike standard radial shaft seals, the Combi/Cassette Seal operates on an integrated axial sealing principle . The internal structure creates a labyrinth path that utilizes centrifugal force to throw contaminants away from the primary sealing lip. This “unitized” construction means the sealing lip runs against an internal precision-ground surface rather than the shaft itself, ensuring that seal performance is independent of shaft surface finish or hardness.

 

Material integrity is the backbone of industrial sealing. Our seals are typically offered in high-grade NBR (Nitrile) for standard hydraulic oil and grease applications, providing excellent elastic recovery and abrasion resistance. For high-temperature environments or aggressive chemical exposure, we utilize FKM. The choice of elastomer ensures that the seal maintains its radial load and “memory” even under significant thermal cycling, preventing the hardening that leads to premature leakage.

One of the primary advantages of the 45 *60 *16/17 Cassette Seal is its “fit and forget” installation profile. Because the seal contains its own running surface, there is no need for specialized shaft hardening or expensive sleeve repairs during maintenance. The robust outer casing allows for a more forgiving installation process in field conditions. By reducing the friction torque, these seals minimize power loss and heat generation, significantly extending the Mean Time Between Failures (MTBF) for heavy-duty drivetrains.

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.
