It introduces the accuracy of the main dimensions and rotational accuracy of bearings.
This document introduces the "accuracy of major dimensions and rotational accuracy" of bearings. The tolerances and allowable values for the major dimensions of small diameter ball bearings and miniature ball bearings, as well as rotational accuracy, comply with JIS B 1514 (Accuracy of rolling bearings) and ANSI/ABMA Std.12.2 (INSTRUMENT BALL BEARINGS INCH DESIGN). It also includes tables of tolerances and allowable values for the outer rings of ball bearings (metric system), as well as a list of major dimensions and rotational accuracy symbols. [Included Tables (Partial)] ■ Tolerances and allowable values for the inner rings of ball bearings, as well as tolerances and allowable values for the width of the outer rings. *For more details, please refer to the PDF document or feel free to contact us.
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.
