It is designed to restore worn, grooved, or damaged shaft sealing surfaces without requiring shaft replacement or machining. Manufactured from high-quality stainless steel, the thin-wall sleeve installs directly over the existing shaft to provide a smooth, wear-resistant sealing surface for standard radial shaft oil seals. The National 99210 Redi-Sleeve® is commonly used in industrial gearboxes, pumps, compressors, electric motors, conveyors, agricultural machinery, and heavy-duty rotating equipment. Maintenance teams, OEMs, and system integrators rely on it for equipment repairs, retrofit projects, seal restoration, and preventive maintenance to reduce downtime 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=\"877\" data-end=\"894\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"895\" data-end=\"1473\"\u003eThe Timken National 99210 Redi-Sleeve® 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 restores proper sealing performance with minimal change to shaft dimensions, making it ideal for industrial gearboxes, pumps, compressors, electric motors, wheel-end assemblies, conveyors, agricultural equipment, and other rotating machinery 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=\"1475\" data-end=\"1504\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1505\" data-end=\"2523\"\u003e• Manufacturer Part Number (MPN): 99210\u003cbr data-start=\"1544\" data-end=\"1547\"\u003e• Manufacturer: Timken National\u003cbr data-start=\"1578\" data-end=\"1581\"\u003e• Product Type: Shaft Repair Sleeve (Redi-Sleeve®)\u003cbr data-start=\"1631\" data-end=\"1634\"\u003e• Product Series: Redi-Sleeve® 99000 Series\u003cbr data-start=\"1677\" data-end=\"1680\"\u003e• Material: Stainless Steel\u003cbr data-start=\"1707\" data-end=\"1710\"\u003e• Design Units: Inch (Imperial)\u003cbr data-start=\"1741\" data-end=\"1744\"\u003e• Shaft Size Range: 2.123–2.128 in (53.924–54.051 mm)\u003cbr data-start=\"1797\" data-end=\"1800\"\u003e• Nominal Shaft Diameter: 2.125 in (53.99 mm)\u003cbr data-start=\"1845\" data-end=\"1848\" data-is-only-node=\"\"\u003e• Flanged Outside Diameter: 2.422 in (61.519 mm)\u003cbr data-start=\"1896\" data-end=\"1899\"\u003e• Width on Shaft (Seal Running Surface): 0.500 in (12.70 mm)\u003cbr data-start=\"1959\" data-end=\"1962\"\u003e• Overall Width: 0.750 in (19.05 mm)\u003cbr data-start=\"1998\" data-end=\"2001\"\u003e• Installation Depth: 1.281 in (32.537 mm)\u003cbr data-start=\"2043\" data-end=\"2046\"\u003e• Construction: Precision Thin-Wall Stainless Steel Sleeve with Installation Flange\u003cbr data-start=\"2129\" data-end=\"2132\"\u003e• Function: Restores worn shaft sealing surfaces without shaft replacement or machining\u003cbr data-start=\"2219\" data-end=\"2222\"\u003e• Compatible Components: Standard radial shaft oil seals for approximately 2.125 in shaft diameters\u003cbr data-start=\"2321\" data-end=\"2324\"\u003e• Typical Applications: Pumps, gearboxes, compressors, electric motors, conveyors, agricultural equipment, 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=\"2525\" data-end=\"2549\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2550\" data-end=\"2672\"\u003e• SKF Speedi-Sleeve 99210\u003cbr data-start=\"2575\" data-end=\"2578\"\u003e• National Redi-Sleeve 99210 Equivalent\u003cbr data-start=\"2617\" data-end=\"2620\"\u003e• CR Shaft Repair Sleeve for 2.125 in Shaft Diameter\u003c\/p\u003e","brand":"Timken","offers":[{"title":"New","offer_id":51714040103214,"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_5ad68992-7b77-45c2-a4c5-642923368576.jpg?v=1770414628","url":"https:\/\/plgautomation.com\/products\/timken-national-99210-redi-sleeve-shaft-repair-sleeve","provider":"PLG Automation ","version":"1.0","type":"link"}
