Track bearings preload is an important aspect in the field of mechanical engineering. It plays a crucial role in ensuring the optimal performance and longevity of track bearing systems. In this article, we will explore the concept of track bearings preload in detail and its significance in various applications.

Understanding Track Bearings Preload

Track bearings preload refers to the axial force applied to the bearings in a track system to eliminate any internal clearance and ensure proper contact between the rolling elements and the raceways. This preload is essential to prevent excessive displacement, reduce vibration, and improve the overall stiffness and accuracy of the system.

Types of Preload

There are several methods to achieve track bearings preload, including:

  • 1. Axial Preload: This method involves applying an axial force to the bearings in the direction of the track. It ensures proper alignment and eliminates any play or looseness in the system.
  • 2. Radial Preload: Radial preload involves applying a radial force to the bearings perpendicular to the track axis. It helps to eliminate radial play and improve the system’s stability.
  • 3. Combination Preload: In some cases, a combination of axial and radial preload is used to achieve optimal performance and load distribution in the track bearing system.

Benefits of Track Bearings Preload

The proper preload in track bearings offers several advantages:

  • 1. Enhanced Rigidity: Preload improves the stiffness of the system, reducing deflection and ensuring precise motion control.
  • 2. Reduced Clearance: By eliminating internal clearance, preload minimizes backlash and improves positional accuracy.
  • 3. Increased Load Capacity: Proper preload ensures optimal load distribution, allowing the bearings to withstand higher loads and operate efficiently.

Applications of Track Bearings Preload

Track bearings preload finds applications in various industries, including:

  • 1. Industrial Automation: Preload is crucial in automated systems where precise movement and positioning are required.
  • 2. Robotics: Robotic systems heavily rely on preload to achieve accurate and repeatable motion control.
  • 3. Machine Tools: Track bearings preload improves the performance and accuracy of machine tools, ensuring quality production.


In conclusion, track bearings preload is a critical aspect in mechanical engineering that significantly impacts the performance and reliability of track bearing systems. By applying the appropriate preload, engineers can achieve improved rigidity, reduced clearance, and increased load capacity. With its wide range of applications, track bearings preload plays a vital role in modern industries.
