Double Cup","description":"\u003cp\u003eThe Timken 384D is a double tapered cup component from the 300 series, designed to serve as the outer raceway in TDO (Tapered Double Outer) style tapered roller bearing assemblies. With an outside diameter of 3.9370 inches and a cup width of 1.6875 inches, it is used in conjunction with two single-row cone assemblies to form a complete double outer bearing capable of handling both radial and axial loads simultaneously. The TDO configuration provides a wide effective bearing spread, making it well suited for applications where overturning moments are a significant load component. Common applications include industrial gearboxes, heavy equipment axle systems, agricultural machinery, mining equipment, and other power transmission components requiring combined radial and thrust load capacity. The cup features a groove and lubrication holes in the outside diameter to facilitate in-place lubrication, and the open design allows for field adjustment of bearing clearance. Material is chrome steel with standard tolerance and a straight outside diameter. The double cup is separable from its matching cone assemblies, allowing individual replacement of the outer raceway without disturbing the full bearing assembly. Maximum housing fillet radius is 0.03 inches. Part number 384D is a Timken Series 385 component manufactured to imperial dimensions.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0426-01297\u003c\/p\u003e","brand":"Timken","offers":[{"title":"Default Title","offer_id":49559053238512,"sku":"m01297","price":159.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/93E1F8B4-639C-4BDA-B48C-7F8EB25FFD98.jpg?v=1776114269","url":"https:\/\/mroexchange.com\/products\/timken-tapered-roller-bearing-cup-384d-3937-x-1688-in-double-cup-01297","provider":"MRO Exchange","version":"1.0","type":"link"}
