As the inner ring assembly of a tapered roller bearing, it is designed to be paired with a compatible bearing cup—most commonly the Timken 99100—to provide accurate shaft positioning, high load capacity, and extended service life under demanding operating conditions. The 99550 cone is widely used in mining equipment, rolling mills, industrial gearboxes, heavy conveyors, steel processing equipment, and other large rotating machinery. Maintenance teams, OEMs, and system integrators rely on this bearing for equipment replacement, retrofit, expansion, and preventive maintenance to maximize uptime and reduce maintenance costs. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"864\" data-end=\"881\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"882\" data-end=\"1434\"\u003eThe Timken 99550 tapered roller bearing cone is designed for heavy-duty applications where high radial and thrust loads are encountered simultaneously. When matched with the Timken 99100 bearing cup, it delivers precise shaft alignment, low friction, and dependable performance in industrial power transmission systems. Typical applications include rolling mills, mining equipment, crushers, paper mills, marine propulsion systems, heavy conveyors, industrial gearboxes, and other high-capacity rotating equipment. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1436\" data-end=\"1465\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1466\" data-end=\"2506\"\u003e• Manufacturer Part Number (MPN): 99550\u003cbr data-start=\"1505\" data-end=\"1508\"\u003e• Manufacturer: Timken\u003cbr data-start=\"1530\" data-end=\"1533\"\u003e• Product Type: Tapered Roller Bearing Cone\u003cbr data-start=\"1576\" data-end=\"1579\"\u003e• Bearing Type: Single Cone (TS – Tapered Single)\u003cbr data-start=\"1628\" data-end=\"1631\"\u003e• Series: 99000 Series\u003cbr data-start=\"1653\" data-end=\"1656\"\u003e• Design Units: Inch (Imperial)\u003cbr data-start=\"1687\" data-end=\"1690\"\u003e• Bore Diameter (d): 5.5000 in (139.700 mm)\u003cbr data-start=\"1733\" data-end=\"1736\"\u003e• Inner Ring Width (B): 2.6250 in (66.675 mm)\u003cbr data-start=\"1781\" data-end=\"1784\" data-is-only-node=\"\"\u003e• Dynamic Radial Load Rating (C1): 148,000 lbf (660,000 N)\u003cbr data-start=\"1842\" data-end=\"1845\"\u003e• Dynamic Radial Load Rating (C90): 38,500 lbf (171,000 N)\u003cbr data-start=\"1903\" data-end=\"1906\"\u003e• Dynamic Axial Load Rating (Ca90): 26,800 lbf (119,000 N)\u003cbr data-start=\"1964\" data-end=\"1967\"\u003e• Static Radial Load Rating (C0): 231,000 lbf (1,030,000 N)\u003cbr data-start=\"2026\" data-end=\"2029\"\u003e• K Factor: 1.43\u003cbr data-start=\"2045\" data-end=\"2048\"\u003e• G1 Factor: 555.5\u003cbr data-start=\"2066\" data-end=\"2069\"\u003e• G2 Factor: 73.5\u003cbr data-start=\"2086\" data-end=\"2089\"\u003e• Geometry Factor (Cg): 0.146\u003cbr data-start=\"2118\" data-end=\"2121\"\u003e• Effective Center Location: -0.48 in (-12.2 mm)\u003cbr data-start=\"2169\" data-end=\"2172\"\u003e• Maximum Shaft Fillet Radius: 0.280 in (7.10 mm)\u003cbr data-start=\"2221\" data-end=\"2224\"\u003e• Weight: 66.21 lb (30.031 kg)\u003cbr data-start=\"2254\" data-end=\"2257\"\u003e• Compatible Cup: Timken 99100\u003cbr data-start=\"2287\" data-end=\"2290\"\u003e• Typical Applications: Rolling mills, mining equipment, crushers, heavy industrial gearboxes, conveyors, steel processing equipment, and industrial power transmission machinery. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2508\" data-end=\"2532\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2533\" data-end=\"2659\"\u003e• Timken 99550\/99100 Bearing Set\u003cbr data-start=\"2565\" data-end=\"2568\"\u003e• NTN Equivalent Tapered Roller Bearing Cone\u003cbr data-start=\"2612\" data-end=\"2615\"\u003e• SKF Equivalent Tapered Roller Bearing Cone\u003c\/p\u003e","brand":"Timken","offers":[{"title":"New","offer_id":51714039349550,"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_771303fe-af49-4f72-8c67-d5329553f2fe.jpg?v=1770414609","url":"https:\/\/plgautomation.com\/products\/the-timken-company-99550-tapered-roller-bearing-cone","provider":"PLG Automation ","version":"1.0","type":"link"}
