Thin Section Bearings


Thin Section Bearings

Thin Section Ball Bearings are specialized bearings designed for applications where space is limited and weight requirements are stringent. They feature a unique thin-walled structure that allows them to provide high performance and high precision while significantly reducing the weight and size of the bearing.

Thin Section Deep Groove Ball Bearings

Thin Section Deep Groove Ball Bearings

Thin Section Deep Groove Ball Bearings are a type of thin-walled bearing. Through improved design, they achieve significant reductions in weight and size, making them suitable for special applications that require lightweight and high precision.


  • Thin-Walled Design:
    The inner and outer rings of thin-walled bearings are relatively thin, and the clearance between the raceway and the rolling elements is smaller. This design significantly reduces the volume and weight of the bearing.
  • High Precision:
    Thin-walled bearings are typically manufactured using high-precision processes, ensuring stable and high-precision operation.
  • Various Cross-Sections and Sizes:
    Thin-walled bearings are available in a variety of cross-sections and sizes to meet different design requirements.

Thin-walled deep groove ball bearings, due to their unique thin-walled design, high precision, and high performance, are widely used in aerospace, robotics, medical equipment, precision instruments, and industrial machinery.


Thin-walled bearings are mainly categorized into several types, including thin-walled deep groove ball bearings, thin-walled four-point contact ball bearings, thin-walled angular contact ball bearings, thin-walled crossed roller bearings, thin-walled thrust ball bearings, and thin-walled thrust roller bearings.

Choosing the right thin-walled bearing involves considering the following factors:

  • Load Requirements: The magnitude of radial and axial loads.
  • Space Constraints: The available installation space.
  • Operating Speed: The speed at which the bearing needs to operate.
  • Environmental Conditions: The temperature, humidity, and contamination level of the working environment.
  • Precision Requirements: The precision level required for the equipment's operation

The load capacity of thin-walled bearings depends on their type and size. Generally, despite having thinner inner and outer rings, thin-walled bearings still offer high radial and axial load capacities. The specific load capacity can be determined from the product specification sheet.

The lifespan of thin-walled bearings depends on several factors, including load magnitude, operating speed, lubrication conditions, and working environment. With proper maintenance and suitable operating conditions, thin-walled bearings can last for many years. Regularly checking and maintaining the lubrication state, keeping the environment clean, and promptly replacing worn bearings can significantly extend their service life.
