What is the production process of crossed roller bearings?

Подшипники с перекрестными роликами are a type of precision bearings designed for applications that require high rotational accuracy and stiffness, with the ability to handle both radial and axial loads. The production process of crossed roller bearings involves several key steps. While the exact details can vary among manufacturers, the following is a general overview of the production process.

Crossed roller bearing production process

Выбор материала

• High-quality materials, typically bearing steel, are chosen for the inner and outer rings, ролики, и другие компоненты. The specific alloy composition and heat treatment are critical to achieving the desired mechanical properties.

Forging and Heat Treatment

• The selected materials undergo a forging process to form rough shapes of the inner and outer rings. Subsequently, heat treatment is applied to enhance the hardness, сила, and wear resistance of the components.

Machining Inner and Outer Rings

• The forged rings undergo precision machining to achieve the final dimensions, smooth surfaces, and accurate geometries required for optimal performance. This step includes processes such as turning, измельчение, and honing.

Roller Production

• Rollers are manufactured separately, often through a precision machining process, to ensure uniform size and shape. Heat treatment is applied to achieve the desired hardness.
