Bearing Technical Information: Fits and Clearances

This introduces the "fit" and "clearance" of bearings.

This document introduces the "fit and clearance" of bearings. The fit conditions for incorporating bearings into equipment are extremely important for fully realizing the performance of the equipment. Additionally, the size of the internal clearance during bearing operation significantly affects the bearing's performance, including fatigue life, vibration, noise, and heat generation. Therefore, it is necessary to select an appropriate radial internal clearance considering the fit, bearing load, rotational speed, and bearing temperature during operation. Furthermore, the document presents information on fits, including the fit between the inner ring and the shaft, as well as the fit between the outer ring and the housing bore, using tables and examples. [Contents (partial)] ■ Fit *For more details, please refer to the PDF document or feel free to contact us.

Bearing Technology Information: Bearing Lifespan

It introduces the lifespan of bearings, as well as the basic dynamic load ratings and fatigue life.

This document explains the "lifetime of bearings." Even when rolling bearings are used correctly for a specific application, after a certain period of time, they may become unusable due to increased noise and vibration, decreased accuracy from wear, degradation of the lubricating grease, and fatigue of the rolling surfaces. The period until they become unusable is referred to as the broad definition of bearing lifetime, which includes terms such as acoustic lifetime, wear lifetime, grease lifetime, and rolling fatigue lifetime. Additionally, the basic dynamic load rating of bearings and fatigue lifetime are also explained using calculation formulas.

Bearing Technical Information: Allowable Rotational Speed

As bearing technical information, we introduce the permissible rotational speed of bearings.

Each bearing has a limit to its rotational speed. When a bearing is operated, as the rotational speed increases, the temperature rise due to frictional heat inside the bearing becomes greater. The limit of rotational speed is an empirical tolerance value that allows the bearing to continue operating without causing seizure or excessive heat generation beyond a certain limit. Therefore, the permissible rotational speed for each bearing varies depending on the type and dimensions of the bearing, the type and material of the cage, the bearing load, the lubrication method, the lubricant, and the cooling conditions surrounding the bearing. [Key Points] - Each bearing has a limit to its rotational speed. - The limit of rotational speed is an empirical tolerance value that allows the bearing to continue operating without causing seizure or excessive heat generation beyond a certain limit. *For more details, please refer to the PDF document or feel free to contact us.*
