Single-Row Ball Type

Single-row ball slewing ring bearings are the most common type of slewing ring bearing. They consist of a single row of steel balls that run in a circular track. These bearings are ideal for applications that require low friction and high speed. They are also relatively inexpensive and easy to install.

Double-Row Ball Type

Double-row ball slewing ring bearings are similar to single-row ball bearings, but they have two rows of steel balls instead of one. This makes them more durable and able to handle heavier loads. They are commonly used in applications that require high load capacity and high speed.

Crossed Roller Type

Crossed roller slewing ring bearings use crossed cylindrical rollers instead of steel balls. This design allows for a larger contact area between the rollers and the raceway, which makes them ideal for applications that require high precision and stiffness. They are commonly used in robotics, machine tools, and other high-precision applications.

Three-Row Roller Type

Three-row roller slewing ring bearings are the most heavy-duty type of slewing ring bearings. They have three rows of cylindrical rollers that run in a circular track. This design allows them to handle extremely heavy loads and high overturning moments. They are commonly used in large construction equipment, cranes, and wind turbines.

When choosing a slewing ring bearing, it’s important to consider factors such as load capacity, speed, precision, and cost. By understanding the different types of slewing ring bearings available, you can choose the one that best meets your specific needs.

Design Specifications

When selecting a slewing bearing, it is important to consider its design specifications. Here are some key factors to keep in mind:

Gear Types

Slewing bearings can come with different gear types, including internal, external, and no gears. Internal gears are often used for slow-moving applications, while external gears are better suited for high-speed applications. If you don’t need gears, you can opt for a bearing with no gears.

Materials and Heat Treatment

The materials used to make slewing bearings can vary, but common options include chrome steel, stainless steel, and carbon steel. Heat treatment can also affect the bearing’s performance. For example, if the bearing is going to be used in high-temperature environments, it may need to be heat-treated to improve its resistance to thermal expansion.

Sealing Systems

Sealing systems are important for protecting the bearing from contaminants and moisture. Different types of sealing systems are available, including single lip, double lip, and triple lip seals. You should choose the sealing system that best meets your needs based on the operating conditions of the bearing.

Overall, selecting the right slewing bearing requires careful consideration of its design specifications. By taking into account factors such as gear types, materials and heat treatment, and sealing systems, you can find a bearing that will perform well in your specific application.
