Hardness Requirements to Protect Tungsten Carbide Bushings","og_description":"Tungsten carbide bushings are designed to handle tough industrial environments, but they can wear out prematurely if paired with shafts that don\u2019t meet the right hardness requirements. The hardness of the shaft has a significant impact on the lifespan and performance of tungsten carbide bushings. In this article, we will explore the importance of shaft hardness, how it protects WC bushings, and what the right hardness values should be for different applications. Why Shaft Hardness Matters for Tungsten Carbide Bushings The hardness of the shaft paired with a tungsten carbide bushing affects the wear and tear each component experiences during operation. If the shaft is too soft, it can wear [&hellip;]","og_url":"https:\/\/www.retopz.com\/ja\/shaft-hardness-requirements-to-protect-tungsten-carbide-bushings\/","og_site_name":"Retop
