Achieving the required surface quality depends on the choice and quality of the machining process.<\/p><h4>Freedom from Twist<\/h4><p>The mating surface of the shaft should be free of twist or orientation. During machining, a twist orientation (similar to a micro-thread) can develop, causing the medium to be conveyed. Depending on the direction of rotation, this can either support or counteract the sealing effect of the radial shaft seal. If the twist orientation of the shaft exceeds that of the shaft seal, leakage will occur. In applications with only one direction of rotation, this behavior can be used to enhance the sealing effect.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-b18020d\" data-id=\"b18020d\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-332e4ce elementor-widget elementor-widget-text-editor\" data-id=\"332e4ce\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h4>\u00a0<\/h4><h4>Plunge Grinding<\/h4><p>To create a torsion-free surface, we recommend plunge grinding (without axial feed). However, specific parameters must be observed to ensure a twist-free surface:<\/p><p>&#8211; The speed ratio between the grinding wheel and the workpiece must not be a whole number.<br \/>&#8211; Orientation can transfer to the grinding wheel. Therefore, use multi-grain dressing tools with the lowest possible axial feed or professional dressing rolls.<br \/>&#8211; The dressing time should be as long as possible until complete burnout is achieved.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-196a62a elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"196a62a\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-8686efa\" data-id=\"8686efa\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-9afd199 elementor-widget elementor-widget-image\" data-id=\"9afd199\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"567\" height=\"378\" src=\"https:\/\/www.vr-dichtungen.com\/wp-content\/uploads\/2024\/04\/CH093_Produktion_1582.png\" class=\"attachment-large size-large wp-image-1168\" alt=\"\" srcset=\"https:\/\/www.vr-dichtungen.com\/wp-content\/uploads\/2024\/04\/CH093_Produktion_1582.png 567w, https:\/\/www.vr-dichtungen.com\/wp-content\/uploads\/2024\/04\/CH093_Produktion_1582-300x200.png 300w\" sizes=\"(max-width: 567px) 100vw, 567px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-df82ba8 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"df82ba8\" data-element_type=\"section\" data-e-type=\"section\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-4a77d19\" data-id=\"4a77d19\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-aece487 elementor-widget elementor-widget-image\" data-id=\"aece487\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"594\" height=\"694\" src=\"https:\/\/www.vr-dichtungen.com\/wp-content\/uploads\/2024\/06\/Gehause.webp\" class=\"attachment-large size-large wp-image-4063\" alt=\"\" srcset=\"https:\/\/www.vr-dichtungen.com\/wp-content\/uploads\/2024\/06\/Gehause.webp 594w, https:\/\/www.vr-dichtungen.com\/wp-content\/uploads\/2024\/06\/Gehause-257x300.webp 257w\" sizes=\"(max-width: 594px) 100vw, 594px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-3e5f4db\" data-id=\"3e5f4db\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-037cbad elementor-widget elementor-widget-heading\" data-id=\"037cbad\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Housing bore<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c22d51d elementor-widget elementor-widget-text-editor\" data-id=\"c22d51d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>In addition to the dynamic seal between the seal lip and the shaft, a radial shaft seal also provides a static seal between its outer diameter and the locating bore.
