Installed directly over the existing shaft, it creates a smooth, wear-resistant sealing surface that extends the service life of standard radial shaft oil seals while reducing maintenance costs and equipment downtime. The 99212 Redi-Sleeve is widely used in industrial gearboxes, pumps, compressors, electric motors, conveyors, agricultural machinery, and heavy-duty rotating equipment. Maintenance teams, OEMs, and system integrators rely on this shaft repair sleeve for equipment repairs, retrofit projects, seal restoration, and preventive maintenance. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"831\" data-end=\"848\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"849\" data-end=\"1490\"\u003eThe Timken National Redi-Sleeve 99212 is designed to repair worn shaft seal contact surfaces and restore dependable sealing performance while allowing continued use of the original shaft and standard oil seal size. Its precision thin-wall stainless steel construction provides a hardened, corrosion-resistant running surface with minimal effect on 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=\"1492\" data-end=\"1521\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1522\" data-end=\"2616\"\u003e• Manufacturer Part Number (MPN): 99212\u003cbr data-start=\"1561\" data-end=\"1564\"\u003e• Manufacturer: Timken National\u003cbr data-start=\"1595\" data-end=\"1598\"\u003e• Product Type: Shaft Repair Sleeve (Redi-Sleeve®)\u003cbr data-start=\"1648\" data-end=\"1651\"\u003e• Product Series: Redi-Sleeve® 99000 Series\u003cbr data-start=\"1694\" data-end=\"1697\"\u003e• Material: Stainless Steel\u003cbr data-start=\"1724\" data-end=\"1727\"\u003e• Design Units: Inch (Imperial)\u003cbr data-start=\"1758\" data-end=\"1761\"\u003e• Shaft Size Range: 2.124–2.130 in (53.95–54.10 mm)\u003cbr data-start=\"1812\" data-end=\"1815\"\u003e• Nominal Shaft Diameter: 2.127 in (54.03 mm)\u003cbr data-start=\"1860\" data-end=\"1863\" data-is-only-node=\"\"\u003e• Flanged Outside Diameter: 2.422 in (61.52 mm)\u003cbr data-start=\"1910\" data-end=\"1913\"\u003e• Width on Shaft (Seal Running Surface): 0.781 in (19.84 mm)\u003cbr data-start=\"1973\" data-end=\"1976\"\u003e• Overall Width: 0.938 in (23.83 mm)\u003cbr data-start=\"2012\" data-end=\"2015\"\u003e• Installation Depth: 1.375 in (34.93 mm)\u003cbr data-start=\"2056\" data-end=\"2059\"\u003e• Construction: Precision Thin-Wall Stainless Steel Sleeve with Installation Flange\u003cbr data-start=\"2142\" data-end=\"2145\"\u003e• Surface Finish: Precision Ground, 10–20 μin Ra (0.25–0.50 μm Ra), Lead-Free\u003cbr data-start=\"2222\" data-end=\"2225\"\u003e• Function: Restores worn shaft sealing surfaces without shaft replacement or machining\u003cbr data-start=\"2312\" data-end=\"2315\"\u003e• Compatible Components: Standard radial shaft oil seals for approximately 2.126 in shaft diameters\u003cbr data-start=\"2414\" data-end=\"2417\"\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=\"2618\" data-end=\"2642\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2643\" data-end=\"2765\"\u003e• SKF Speedi-Sleeve 99212\u003cbr data-start=\"2668\" data-end=\"2671\"\u003e• National Redi-Sleeve 99212 Equivalent\u003cbr data-start=\"2710\" data-end=\"2713\"\u003e• CR Shaft Repair Sleeve for 2.126 in Shaft Diameter\u003c\/p\u003e","brand":"Timken","offers":[{"title":"New","offer_id":51714040070446,"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_c51b8d5c-c0d9-4e3c-8608-da9e58b6cda1.jpg?v=1770414627","url":"https:\/\/plgautomation.com\/products\/the-timken-company-99212-redi-sleeve-shaft-repair-sleeve","provider":"PLG Automation ","version":"1.0","type":"link"}
