Product Description

Product Description

Spherical roller bearings are a type of roller bearing that can accommodate heavy radial loads and axial loads in both directions. They have two rows of barrel-shaped rollers that run on a common spherical outer ring raceway. The inner ring of the bearing is also designed to have a spherical shape, allowing for misalignment between the shaft and housing.

Advantages of spherical roller bearings include:

High load capacity: Spherical roller bearings can handle heavy radial and axial loads due to their design and construction.

Self-aligning: The spherical shape of the inner and outer rings allows for misalignment between the shaft and housing, reducing stress and wear on the bearing.

Durable: Spherical roller bearings are made from high-quality materials and are designed to withstand harsh operating conditions.

Versatile: They can be used in a wide range of applications, including mining, construction, and industrial equipment.

Long service life: With proper maintenance, spherical roller bearings can last for many years, reducing downtime and maintenance costs.
