Sealed double row spherical roller bearings

Standard spherical roller bearings are already extremely good bearings from a mechanical point of view. They can handle heavy loads, tolerate misalignment, and have proven themselves for decades.

The Sealed Double Row Spherical Roller Bearings were developed for applications where operating conditions are even more demanding, in more contaminated operating conditions or difficult lubrication conditions.

In these situations, most bearing problems are not caused by the bearing design itself, but by contamination or insufficient lubrication. That is why Sealed Double Row Spherical Roller Bearings were engineered with integrated seals and factory grease filling.

The advantages of Sealed Double Row Spherical Roller Bearings include:

• Improved protection against dirt and water
• Longer grease life
• Reduced maintenance
• Extended service life in harsh environments

Sealed Double Row Spherical Roller Bearings are essentially a specialized development of an already very strong bearing design, created for applications where extra protection and lower maintenance requirements are important.

Sealed spherical roller bearings are often slightly wider than the equivalent open spherical roller bearing.

The extra width mainly comes from:

• Integrated contact seals on both sides
• Seal support grooves/ribs
• Factory grease fill

Sealed double row spherical roller bearings are engineered for demanding industrial environments where reliability, contamination protection, and reduced maintenance are critical. Equipped with integrated contact seals on both sides, these bearings provide excellent protection against dust, moisture, dirt, and other contaminants while retaining lubricant inside the bearing.

Their self-aligning double row roller design enables the bearing to accommodate heavy radial loads and moderate axial loads in both directions. The internal geometry also compensates for shaft misalignment and housing deflection, ensuring stable and efficient operation under challenging working conditions.

Pre-lubricated with high-quality grease, sealed double row spherical roller bearings simplify installation and help reduce maintenance intervals. This makes them particularly suitable for applications where relubrication is difficult or where minimizing downtime is essential.

• Integrated double-sided seals for superior contamination protection
• Factory pre-greased for simplified installation
• High load carrying capacity
• Self-aligning design compensates for shaft misalignment
• Reliable operation in dusty, humid, and harsh environments
• Extended service life
• Reduced lubricant leakage
• Lower maintenance requirements

Sealed double row spherical roller bearings combine robust load performance with advanced sealing technology, making them an ideal solution for industrial applications where durability, operational reliability, and long service life are essential.
