Radial and Thrust Bearings

Rolling bearings are classified into two categories based on the primary direction of the load they bear: radial bearings and thrust bearings.

How to identify the quality of bearings

Bearings are crucial foundational components in a wide variety of mechanical equipment, playing a decisive role in determining the precision, performance, service life, and reliability of machinery. Therefore, bearings must possess excellent quality and performance. At present, the quality of bearings available on the market varies widely, making it easy to purchase counterfeit products that often fail prematurely during use. Below, we’ll discuss how to identify the quality of bearings when making a purchase.

Proper Selection of Turntable Bearings

Commonly used rotary tables in CNC machine tools include indexing rotary tables and CNC rotary tables. When machining certain parts, CNC machine tools not only require linear feed motions along the X, Y, and Z axes but sometimes also need circular motions around the X, Y, and Z axes—referred to as the A, B, and C axes, respectively.

Causes of Abnormal Noise in Crossed Roller Bearings and Identification Methods

The abnormal noises that occur during the operation of crossed roller bearings are diverse in type, with complex formation mechanisms. The factors contributing to these noises are multifaceted, and various abnormal sounds often overlap, making them difficult to distinguish. The main reasons for this phenomenon include the following:

How to inspect bearings

Bearings are fairly common in everyday life, and during operation, they can encounter a wide variety of issues. So, how do we inspect bearings?

Limit speed of bearings—requirements for bearing selection based on rotational speed

Every bearing has its own maximum allowable speed. The rotational speed plays a critical role in determining the temperature rise of the bearing. If a bearing’s rotational speed exceeds its maximum allowable speed, it can lead to increased bearing temperature, drying out of the lubricant, and even cause the bearing to seize up. Therefore, when selecting an appropriate bearing type based on the bearing’s rotational speed, it’s essential to understand the specific requirements for choosing bearings according to their speed.
