Types of Spherical Roller Bearings

Spherical Roller Bearings

5 Different types and features of spherical roller bearings available

Spherical roller bearings are available in various types and designs, each with unique features and benefits to suit different applications.

Here are the 5 main types of spherical roller bearings:

1.Standard Spherical Roller Bearings:

Standard Spherical Roller Bearings are a type of bearing that has a single row of symmetrical spherical rollers with a common spherical raceway in the outer ring.

They are the most common type of spherical roller bearings and are designed to handle both radial and axial loads.

The rollers in a standard spherical roller bearing are arranged in a way that allows them to self-align, compensating for misalignment between the shaft and housing.

This feature makes them suitable for applications with moderate to high speeds and misalignment.

Standard spherical roller bearings have a high load-carrying capacity, making them ideal for heavy-duty applications such as mining, paper mills, and steel mills.

They are available in both metric and inch sizes, with a range of cage materials and designs to suit different operating conditions.

2.Double Row Spherical Roller Bearings:

Double Row Spherical Roller Bearings are a type of bearing that has two rows of symmetrical spherical rollers with a common spherical raceway in the outer ring.

This design allows the bearing to handle heavy radial loads and some axial loads, making it suitable for applications that require high load capacity.

The symmetrical design of the rollers distributes the load evenly between the two rows, reducing the risk of misalignment and increasing the bearing's overall load-carrying capacity.

Additionally, the double row design provides greater rigidity and stability compared to single row spherical roller bearings.

Double row spherical roller bearings are commonly used in heavy-duty applications, such as mining, construction, and heavy machinery.

They are available in both metric and inch sizes and can operate at moderate to low speeds.

3.Sealed Spherical Roller Bearings:

Sealed Spherical Roller Bearings are a type of bearing that has seals on both sides to prevent contamination from dust and moisture.

They are designed to operate in harsh environments, making them ideal for applications that require additional protection against external elements.

The seals on sealed spherical roller bearings provide a barrier between the bearing's internal components and the external environment, preventing the ingress of dust, dirt, and water.

This feature increases the bearing's service life and reduces the risk of premature failure.

Sealed spherical roller bearings are available in both standard and double row designs, with a range of cage materials and designs to suit different operating conditions.

They are commonly used in applications such as mining, construction, and marine industries, where exposure to harsh environments is prevalent.

4.E-type Spherical Roller Bearings:

E-type Spherical Roller Bearings are a type of bearing that have a high load-carrying capacity and are designed for heavy-duty applications.

They have a stamped steel cage and a unique design that allows the rollers to operate at a steeper angle, resulting in increased load capacity and higher resistance to shock and impact.

The stamped steel cage in E-type spherical roller bearings is durable and lightweight, providing excellent heat dissipation and reducing the risk of cage failure under high loads.

The increased angle of the rollers also reduces the risk of edge stresses and improves lubrication distribution, increasing the bearing's service life.

E-type spherical roller bearings are suitable for moderate to high-speed applications and can operate in harsh environments.

They are commonly used in heavy-duty applications such as mining, construction, and steel mills.

5.X-life Spherical Roller Bearings:

X-life Spherical Roller Bearings are a type of bearing that has an extended service life and is designed for high radial and axial loads.

They feature improved geometry, high-quality surface finish, and optimized internal design, resulting in increased load-carrying capacity, higher speed rating, and longer service life.

The improved geometry of X-life spherical roller bearings reduces stress concentrations, resulting in reduced risk of premature failure under high loads.

The high-quality surface finish also improves the bearing's resistance to wear and corrosion, increasing its durability and reliability.

X-life spherical roller bearings are suitable for high-performance applications, such as aerospace, wind energy, and machine tools, where the demands on the bearing's performance are high.

They are available in both standard and modified designs, with a range of cage materials and designs to suit different operating conditions.
