Introduction Bearing reliability is fundamentally linked to lubrication performance. Industry data consistently shows that a significant percentage of premature bearing failures are lubrication-related\u2014caused by improper lubricant type, contamination, insufficient film thickness, or thermal degradation. One of the most critical decisions in rotating equipment design and maintenance is whether to use lubrication oil or grease. While both serve the same fundamental purpose\u2014reducing friction and wear\u2014their behavior, performance envelope, and maintenance implications differ substantially. This article provides a technical comparison based on lubrication theory, thermal management, contamination control, speed capability, and engineering selection criteria. 2. Lubrication Fundamentals Both oil and grease aim to form an elastohydrodynamic lubrication (EHL) film between rolling [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[28],"tags":[1174,37,1583,43,659,1585,1589,1587,46,31,516,1588,1582,465,1586,1584,717,872,1590],"class_list":["post-1912","post","type-post","status-publish","format-standard","hentry","category-technical-guides","tag-bearing-heat-dissipation","tag-bearing-lubrication","tag-bearing-lubrication-oil-vs-grease","tag-bearing-maintenance","tag-contamination-control","tag-dn-value","tag-ehl-film","tag-elastohydrodynamic-lubrication","tag-grease-lubrication","tag-industrial-bearings","tag-industrial-machinery","tag-lubrication-selection-guide","tag-lubrication-theory","tag-mechanical-engineering","tag-oil-lubrication-system","tag-oil-vs-grease","tag-predictive-maintenance","tag-rolling-element-bearing","tag-rotating-equipment-reliability"],"_links":{"self":[{"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/posts\/1912","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/comments?post=1912"}],"version-history":[{"count":1,"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/posts\/1912\/revisions"}],"predecessor-version":[{"id":1913,"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/posts\/1912\/revisions\/1913"}],"wp:attachment":[{"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/media?parent=1912"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/categories?post=1912"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wonzh.com\/ja\/wp-json\/wp\/v2\/tags?post=1912"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
