Bearing Technology Information: Bearing Lifespan

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

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.*

Plastic ball bearings that do not retain impurities in the solution.

Plastic ball bearings that do not retain impurities in the solution.

The full ball type (without retainer) resin ball bearing is recommended when there is a possibility of issues arising from having a retainer!

Full ball type resin ball bearings do not have retainers, allowing for smooth circulation of the solution within the bearing and making it less likely for impurities to clog the structure. Additionally, in plating lines, metal bearings cannot be used because the plating adheres to the bearings themselves, but plastic bearings can be used in plating baths since they do not get coated. 【Main Applications】 ■ Environments where liquids or solutions containing impurities are present ■ Plating lines for semiconductors and electronic components, cleaning lines ■ Lines in liquids containing impurities, such as underwater ■ Food manufacturing lines where food debris is generated or oil is used *For more details, please download the materials or contact us.

Flash Product Lifespan Predictions You Should Know (3)

Flash Product Lifespan Predictions You Should Know (3)

Easily check the remaining lifespan and replacement timing of SSDs and memory cards, as well as signs of errors, on the operating system. This helps avoid unexpected system shutdowns and data loss.

= Lifespan Diagnosis and Lifespan Prediction = To maintain high performance and data retention capabilities, as well as stable operation during long periods of continuous use, we recommend products optimized for the application, installation environment, and write/read/erase cycles of the system by combining appropriate functions and advanced technologies. Lifespan measures for NAND flash-based storage involve various technologies and functions aimed at maximizing storage lifespan optimization, such as reducing WAF through page-based FTL technology, decreasing the number of block erasures by implementing cache DRAM and garbage collection, and using over-provisioning techniques to increase durability and performance by expanding spare areas. However, accurately understanding the lifespan of storage in practice is very difficult, for example, estimating lifespan or predicting lifespan-related changes from the software access profile on the system (host) side. At Swissbit, the "firmware" and "lifespan diagnosis tool" enable easy visualization of WAF and realistic lifespan predictions, allowing for timely and reliable decisions based on the remaining lifespan of the installed storage and signs of errors, thus preventing unexpected operational downtime and data loss.
