Sealed Tapered Roller Bearings

What Are Sealed Tapered Roller Bearings?

Sealed tapered roller bearings are precision-engineered single-row tapered roller bearings with built-in seals on both sides. Typically, they feature a DUO-FACE PLUS or similar high-performance sealing system pressed onto the large rib of the inner ring. This sealing structure effectively retains lubricant while keeping out contaminants such as dust, dirt, and moisture.

Key Features

• Integrated dual-lip seals for improved dust and water resistance
• Lubricated for life – no need for periodic relubrication in many applications
• Reduced bearing maintenance and longer service life
• Optimized for applications exposed to contaminants or extreme environments

Applications

These bearings are commonly used in:

• Automotive hubs
• Heavy-duty industrial machinery
• Agricultural equipment
• Construction and mining applications

Interchangeable With

Sealed tapered roller bearings are fully interchangeable with equivalent models from major manufacturers such as Timken, making them a flexible and cost-effective solution for OEMs and repair operations.

Why Choose Sealed Tapered Roller Bearings?

Compared to open tapered roller bearings, sealed variants offer superior performance in dirty or wet environments. The integrated seals prevent premature wear caused by contamination, while also retaining lubrication more effectively. This helps reduce total cost of ownership and increases reliability in critical systems.

Conclusion

If you need reliable performance in tough environments, sealed tapered roller bearings are an excellent choice. With their dual-seal protection and compatibility with top-tier brands, they combine convenience, durability, and excellent interchangeability.
