Replacement ROLLIX Slewing Bearings

Rollix is a well-known brand specializing in the manufacturing of high-precision slewing bearings, used in a variety of applications, including wind turbines, cranes, and industrial machinery. They come in a range of types and sizes, tailored to meet specific application requirements. Here’s an overview of the different types of Rollix bearings and their typical size ranges:

Types of Rollix Slewing Bearings

1. Single Row Ball Slewing Bearings

   • Description: These bearings have a single row of balls and are designed for applications where space is limited and load capacity is moderate.
   • Common Applications: Light to medium-duty cranes, excavators, turntables.
   • Typical Sizes: Outer diameters range from 300 mm to 5,000 mm.

2. Double Row Ball Slewing Bearings

   • Description: Featuring two rows of balls, these bearings can handle higher loads compared to single row ball bearings.
   • Common Applications: Heavy-duty cranes, tower cranes, offshore platforms.
   • Typical Sizes: Outer diameters range from 500 mm to 6,000 mm.

3. Cross Roller Slewing Bearings

   • Description: These bearings utilize cylindrical rollers arranged in a crisscross pattern, providing high load capacity and rigidity.
   • Common Applications: Robotics, medical equipment, precision machinery.
   • Typical Sizes: Outer diameters range from 500 mm to 4,000 mm.

4. Triple Row Roller Slewing Bearings

   • Description: With three rows of rollers, these bearings can support very high axial, radial, and tilting moment loads.
   • Common Applications: Heavy-duty construction machinery, offshore cranes, mining equipment.
   • Typical Sizes: Outer diameters range from 1,000 mm to 8,000 mm.

5. Light Series Slewing Bearings

   • Description: These are designed for applications where weight reduction is critical without compromising load capacity.
   • Common Applications: Light cranes, aerial platforms, wind turbines.
   • Typical Sizes: Outer diameters range from 200 mm to 3,000 mm.

Selecting the Right Rollix Slewing Bearing Size

When selecting the right Rollix bearing size for your application, consider the following factors:

1. Load Capacity: Determine the axial, radial, and tilting moment loads the bearing will need to support.
2. Speed Requirements: Consider the rotational speed of the bearing in your application.
3. Installation Space: Ensure the bearing dimensions fit within the available space in your machinery.
4. Precision and Rigidity: Assess the precision and rigidity requirements based on the application’s operational demands.
5. Environmental Conditions: Factor in the operating environment, including temperature, humidity, and exposure to contaminants.
