Installed directly over the existing shaft, it provides a smooth, wear-resistant, and corrosion-resistant sealing surface for standard radial shaft oil seals, extending seal life while reducing maintenance costs and equipment downtime. The 99424 Redi-Sleeve is widely used in industrial gearboxes, pumps, compressors, electric motors, conveyors, mining equipment, and other heavy-duty rotating machinery. Maintenance teams, OEMs, and system integrators rely on this shaft repair sleeve for equipment repairs, retrofit projects, replacement, and preventive maintenance to restore sealing performance and extend equipment service life. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"909\" data-end=\"926\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"927\" data-end=\"1522\"\u003eThe Timken National Redi-Sleeve 99424 is designed to repair worn shaft seal contact surfaces while allowing continued use of the original shaft and standard oil seal size. Its precision thin-wall stainless steel construction provides a hardened sealing surface with minimal impact on shaft dimensions, making it ideal for industrial gearboxes, pumps, compressors, electric motors, wheel-end assemblies, conveyors, agricultural equipment, mining machinery, and other rotating equipment where shaft wear has caused lubricant leakage or premature seal failure. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1524\" data-end=\"1553\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1554\" data-end=\"2698\"\u003e• Manufacturer Part Number (MPN): 99424\u003cbr data-start=\"1593\" data-end=\"1596\"\u003e• Manufacturer: Timken National\u003cbr data-start=\"1627\" data-end=\"1630\"\u003e• Product Type: Shaft Repair Sleeve (Redi-Sleeve®)\u003cbr data-start=\"1680\" data-end=\"1683\"\u003e• Product Series: Redi-Sleeve® 99000 Series\u003cbr data-start=\"1726\" data-end=\"1729\"\u003e• Material: Stainless Steel\u003cbr data-start=\"1756\" data-end=\"1759\"\u003e• Design Units: Inch (Imperial)\u003cbr data-start=\"1790\" data-end=\"1793\"\u003e• Shaft Size Range: 4.248–4.256 in (107.90–108.10 mm)\u003cbr data-start=\"1846\" data-end=\"1849\"\u003e• Nominal Shaft Diameter: 4.250 in (108.00 mm)\u003cbr data-start=\"1895\" data-end=\"1898\" data-is-only-node=\"\"\u003e• Flanged Outside Diameter: 4.813 in (122.25 mm)\u003cbr data-start=\"1946\" data-end=\"1949\"\u003e• Width on Shaft (Seal Running Surface): 0.813 in (20.65 mm)\u003cbr data-start=\"2009\" data-end=\"2012\"\u003e• Overall Width: 1.000 in (25.40 mm)\u003cbr data-start=\"2048\" data-end=\"2051\"\u003e• Installation Depth: 1.375 in (34.93 mm)\u003cbr data-start=\"2092\" data-end=\"2095\"\u003e• Construction: Precision Thin-Wall Stainless Steel Sleeve with Installation Flange\u003cbr data-start=\"2178\" data-end=\"2181\"\u003e• Surface Finish: Precision Ground, Lead-Free Running Surface\u003cbr data-start=\"2242\" data-end=\"2245\"\u003e• Function: Restores worn shaft sealing surfaces without shaft replacement or machining\u003cbr data-start=\"2332\" data-end=\"2335\"\u003e• Compatible Components: Standard radial shaft oil seals for approximately 4.250 in shaft diameters\u003cbr data-start=\"2434\" data-end=\"2437\"\u003e• Weight: Approximately 0.67 lb (0.30 kg)\u003cbr data-start=\"2478\" data-end=\"2481\"\u003e• Typical Applications: Pumps, gearboxes, compressors, electric motors, conveyors, mining equipment, agricultural machinery, wheel hubs, and industrial power transmission systems. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2700\" data-end=\"2724\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2725\" data-end=\"2847\"\u003e• SKF Speedi-Sleeve 99424\u003cbr data-start=\"2750\" data-end=\"2753\"\u003e• National Redi-Sleeve 99424 Equivalent\u003cbr data-start=\"2792\" data-end=\"2795\"\u003e• CR Shaft Repair Sleeve for 4.250 in Shaft Diameter\u003c\/p\u003e","brand":"Timken","offers":[{"title":"New","offer_id":51714039480622,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b50e3957-639f-4f6d-aa05-fbc20cbb0510.jpg?v=1770414613","url":"https:\/\/plgautomation.com\/products\/the-timken-company-99424-redi-sleeve-shaft-repair-sleeve","provider":"PLG Automation ","version":"1.0","type":"link"}
