Good alignment spreads the load across the whole bushing surface.<\/p><\/li><li class=\"li4\"><p>Less Vibration and Noise: Stable rotation protects not only the bushing but also seals, bearings, and pump shafts.<\/p><\/li><li class=\"li4\"><p>Longer Operating Life: With lower friction, lower stress, and better stability, tungsten carbide bushings can last 2\u20134 times longer in many applications.<\/p><\/li><\/ul>\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\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-d37370a e-flex e-con-boxed e-con e-parent\" data-id=\"d37370a\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-3b9b1dc elementor-widget elementor-widget-text-editor\" data-id=\"3b9b1dc\" 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<h2 class=\"p1\"><b>Best Practices for Maintaining Alignment<\/b><\/h2><p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-13747 size-full\" src=\"https:\/\/www.retopz.com\/wp-content\/uploads\/2025\/11\/How-to-Improve-Shaft-Alignment-for-Longer-Bushing-Life-www.retopz.com-6.jpg\" alt=\"\" width=\"660\" height=\"440\" srcset=\"https:\/\/www.retopz.com\/wp-content\/uploads\/2025\/11\/How-to-Improve-Shaft-Alignment-for-Longer-Bushing-Life-www.retopz.com-6.jpg 660w, https:\/\/www.retopz.com\/wp-content\/uploads\/2025\/11\/How-to-Improve-Shaft-Alignment-for-Longer-Bushing-Life-www.retopz.com-6-300x200.jpg 300w, https:\/\/www.retopz.com\/wp-content\/uploads\/2025\/11\/How-to-Improve-Shaft-Alignment-for-Longer-Bushing-Life-www.retopz.com-6-18x12.jpg 18w\" sizes=\"(max-width: 660px) 100vw, 660px\" \/><\/p><ul class=\"ul1\"><li class=\"li3\"><p>Use High-Quality Shims: Shims improve vertical alignment.
