How to choose the right precision bearing

In the fields of mechanical engineering and industrial automation, choosing the right precision bearing is crucial. Choosing suitable precision bearings is a key step to ensure smooth operation and long service life of equipment. Whether in aerospace, medical equipment or industrial production, they all need to operate accurately, stably and reliably. This article will discuss in detail how to choose the right precision bearing among many factors to ensure the smooth operation of the project or equipment.

How to choose suitable precision bearings?

1. Determine the bearing type

The first step in selecting the right precision bearing is to determine the type of bearing required. Such as rolling bearings or sliding bearings. Different types of bearings are suitable for different applications. Rolling bearings include deep groove ball bearings, tapered roller bearings and cylindrical roller bearings. They are suitable for high speed and high load applications, providing lower friction and higher accuracy. Sliding bearings, such as sliding sleeve bearings, are suitable for some high-load, low-speed applications, and they rely on a lubricating film to reduce friction and support the bearing.

2. Determine size and load requirements

Determine the load requirements for your application, including radial and axial loads. As well as the required bearing size, the size of the bearing usually includes the inner diameter, outer diameter and width. Bearing size and load capacity will influence bearing selection.

3. Consider the speed

The speed at which the bearing will operate is also an important factor. High-speed applications often require bearings with higher precision and lower friction to avoid excessive friction heat and vibration. For high-speed applications, choose bearings with higher precision levels to ensure that the bearings do not experience abnormal vibration or overheating problems when running at high speeds.

4. Determine the working environment

Consideration of the working environment is crucial for bearing selection. Various environmental factors can affect bearing performance and life.

4.1.Temperature and humidity

Consider temperature and humidity changes in the work environment. Some bearings need to operate under extreme temperature conditions, while other bearings may need to be corrosion-resistant.

Crossed Roller Bearing Load Analysis

Crossed roller bearings are specialized types of rolling element bearings designed to provide high stiffness and high accuracy in applications where rotational accuracy, rigidity, and space efficiency are crucial. Load analysis for a crossed roller bearing involves determining the loads that the bearing can withstand while maintaining its intended performance.

Crossed Roller Bearing Load Analysis

Crossed roller bearings

Radial Load Capacity

Dynamic Load Rating (C): The dynamic load rating of a bearing is the calculated constant radial load (in Newtons or Pounds) that a group of identical bearings can endure for a rating life of one million revolutions. It is an important factor in determining the bearing’s ability to handle radial loads during normal operation.

Static Load Rating (Co): The static load rating represents the maximum radial load that a bearing can support without permanent deformation. This is important when analyzing applications with static or slowly changing radial loads.

Axial Load Capacity

Dynamic Axial Load Rating (Ca): Similar to the dynamic radial load rating, the dynamic axial load rating is the calculated constant axial load that a group of identical bearings can endure for a rating life of one million revolutions.

Static Axial Load Rating (Coa): The static axial load rating represents the maximum axial load that a bearing can support without permanent deformation.

Combined Radial and Axial Loads

Equivalent Radial Load (P): In applications where both radial and axial loads are present, the equivalent radial load is calculated to simplify the load analysis. It allows for the combination of radial and axial loads into a single radial load value.

Equivalent Dynamic Radial Load (Pdynamic): This is the calculated equivalent radial load when axial and radial loads are combined. It is used to determine the bearing life when both types of loads are present.

Equivalent Static Radial Load (Pstatic): Similar to the equivalent dynamic radial load, this is the calculated equivalent radial load when both axial and radial loads are present, but in a static (non-rotating) condition.

What is the production process of thin-walled bearings?

Thin-walled bearings, also known as thin-section bearings or slim bearings, are specialized bearings with a thin cross-section. The production process of thin-walled bearings involves several key steps. It’s important to note that the specific details may vary among manufacturers, but the following provides a general overview of the production process.

Thin wall bearing production process

Thin-walled bearings

Material Selection

The production process begins with the selection of suitable materials. Thin-walled bearings are often made from high-quality steel or stainless steel, which provides the necessary strength and corrosion resistance.

Cutting Raw Material

The selected raw material is cut into the initial shape, typically in the form of rings or tubes. Precision cutting is crucial to achieving the required dimensions for the thin-walled bearing.

Cold Forming or Turning

The initial shape undergoes a forming process, which can involve cold forming or turning. Cold forming is a process where the material is shaped at room temperature without the use of heat. Turning involves the removal of material to achieve the desired shape.

Heat Treatment

The formed or turned components undergo heat treatment to enhance their mechanical properties. Heat treatment processes may include quenching and tempering to achieve the desired hardness, strength, and toughness.

Grinding

Precision grinding is a critical step to achieve the tight tolerances required for thin-walled bearings. Grinding ensures a smooth surface finish and precise dimensions for proper fit and functionality.
