Welcome to our buying guide dedicated to bearings, essential parts for many mechanical applications. Choosing the right type of bearing is crucial to ensuring optimum performance and long life for your systems. In this guide, we'll explore ball, roller and needle bearings in detail, focusing on their technical characteristics, their differences and the key steps for selecting them

I. Why choose a self-aligning ball bearing?

 

Design:

Self-aligning bearings with spherical outer ring compensate for static shaft misalignment in bearing housings with spherical bore. They can be relubricated if necessary, and are particularly easy to fit thanks to their special mounting arrangements

 

Advantages :

  • Misalignment : Self-aligning ball bearings can compensate for static and dynamic misalignment of up to 3°.
  • Service life: These bearings offer excellent high-speed performance and generate much less heat and friction than other types of ball bearing. This enables them to run cooler, extending their service life and reducing maintenance.
  • Light-load performance: This type of bearing has very low load requirements, which means they perform excellently even under light loads.
  • Low noise: Self-aligning ball bearings produce low noise levels due to the free conformity between the balls and the outer ring. This makes them particularly suitable for use in household appliances such as fans and air conditioners.

 

Fields of application :

Applications for self-aligning ball bearings can be found in a variety of industries, such as mining, the food industry and mass production, such as the textile industry.

I. Why choose a self-aligning bearing?

 

Design:

Bearing housings, also known as mounted or journal bearings, are used to support and guide the shaft of a machine or piece of equipment, enabling smooth rotational movements and reducing friction between contacting surfaces. Housing bearings are designed to provide efficient shaft support and rotation, while minimizing friction and energy loss. They generally consist of three main components: the rolling element, the cage and the housing.

 

Advantages :

  • Reduced friction: They enable smooth shaft rotation by reducing friction between moving surfaces, resulting in lower energy consumption and longer component life.
  • Load-bearing capacity: Bearing units are designed to support radial and axial loads, enabling efficient transfer of the forces generated by the system.
  • Ease of installation and maintenance: They are generally easy to install and maintain, enabling fast and efficient maintenance operations.

 

Applications:

Housing bearings are used in a wide range of applications, including:

  • Industrial machinery: They are used in machine tools, compressors, electric motors, pumps, conveyors, etc.
  • Automotive: Used in engines, gearboxes, axles and suspension systems.
  • Agricultural equipment: Used in agricultural machinery, tractors, combines, etc.
  • Domestic applications: used in household appliances, fans, water pumps, etc.

What are the different types of clamping in bearing housings?

  • Bearing with eccentric ring :

 

This type of bearing uses an eccentric ring that can be rotated around the shaft to create a controlled axial misalignment. The ring is usually fixed inside the bearing housing. By turning the ring, the axial position of the shaft relative to the housing can be adjusted. This design compensates for misalignment between shaft and housing.

  • Housing bearing with adapter sleeve :


In this type of bearing, an adapter sleeve is used to secure the shaft to the housing. The adapter sleeve usually consists of a slotted cylindrical sleeve with an adapter nut. When the clamping nut is tightened, it clamps the clamping sleeve around the shaft, creating a secure fit. This type of bearing offers ease of installation and disassembly, enabling bearings to be easily replaced.

  • Pressure screw bearing:


This type of bearing uses setscrews to secure the shaft to the housing. The setscrews are generally arranged equidistantly around the bearing housing. When tightened, they exert pressure on the shaft, creating a firm hold. These bearings offer high axial load capacity and are often used in applications requiring high precision.

PLEASE NOTE:

 

When using bearings for a specific application, it's important to consider sealing.

The importance of sealing lies in its ability to protect your bearings from harmful elements such as dust, moisture and contaminants. By ensuring proper sealing, you can significantly extend the life, improve the performance and increase the reliability of your bearings. This significantly reduces the risk of premature wear and bearing failure.

Understanding bearing sealing

By following these tips, you should be able to choose the belts that are best suited to your application, and that operate safely and efficiently.
