Tapered roller bearings consist of four interdependent components: the cone (inner ring), the cup (outer ring), the tapered rollers (rolling elements) and the cage (roller retainer). Tapered roller bearings are uniquely designed to manage both thrust and radial loads between a rotating and non-rotating member. The steeper the cup angle, the greater the ability of the bearing to handle thrust loads.\u003cbr\u003e\u003cbr\u003eIndustries:\u003cbr\u003eAerospace, agriculture, automotive, heavy truck, cement, aggregate, coal, oil and gas, construction, gear drives, machine tools, mining, paper, metals, rail and wind.\u003cbr\u003e\u003cbr\u003eBenefits:\u003cbr\u003eEnhanced performance in demanding applications.\u003cbr\u003e\u003cbr\u003eSeries\u003cbr\u003e    385\u003cbr\u003eCone Part Number\u003cbr\u003e    387A\u003cbr\u003eCup Part Number\u003cbr\u003e    382A\u003cbr\u003eDesign Unit\u003cbr\u003e    Inch\u003cbr\u003eCage Material\u003cbr\u003e    Stamped Steel\u003cbr\u003eRelated Assembly Number(s)\u003cbr\u003e    387A-90409\u003cbr\u003eDimensions\u003cbr\u003ed - Bore\u003cbr\u003e    2 1\/4 in 57.150 mm\u003cbr\u003eD - Cup Outer Diameter\u003cbr\u003e    3.8125 in 96.838 mm\u003cbr\u003eB - Cone Width\u003cbr\u003e    0.8640 in 21.946 mm\u003cbr\u003eC - Cup Width\u003cbr\u003e    0.6250 in 15.875 mm\u003cbr\u003eT - Bearing Width\u003cbr\u003e    0.8268 in 21.001 mm\u003cbr\u003eAbutment and Fillet Dimensions\u003cbr\u003eR - Cone Backface \"To Clear\" Radius1\u003cbr\u003e    0.14 in 3.600 mm\u003cbr\u003er - Cup Backface \"To Clear\" Radius2\u003cbr\u003e    0.030 in 0.76 mm\u003cbr\u003eda - Cone Frontface Backing Diameter\u003cbr\u003e    2.48 in 63 mm\u003cbr\u003edb - Cone Backface Backing Diameter\u003cbr\u003e    2.76 in 70 mm\u003cbr\u003eDa - Cup Frontface Backing Diameter\u003cbr\u003e    3.66 in 92.96 mm\u003cbr\u003eDb - Cup Backface Backing Diameter\u003cbr\u003e    3.50 in 88.90 mm\u003cbr\u003eAb - Cage-Cone Frontface Clearance\u003cbr\u003e    0.11 in 2.8 mm\u003cbr\u003eAa - Cage-Cone Backface Clearance\u003cbr\u003e    0.03 in 0.8 mm\u003cbr\u003ea - Effective Center Location3\u003cbr\u003e    -0.12 in -3 mm\u003cbr\u003eBasic Load Ratings\u003cbr\u003eC90 - Dynamic Radial Rating (90 million revolutions)4\u003cbr\u003e    6280 lbf 28000 N\u003cbr\u003eC1 - Dynamic Radial Rating (1 million revolutions)5\u003cbr\u003e    24200 lbf 108000 N\u003cbr\u003eC0 - Static Radial Rating\u003cbr\u003e    24100 lbf 107000 N\u003cbr\u003eCa90 - Dynamic Thrust Rating (90 million revolutions)6\u003cbr\u003e    3810 lbf 16900 N\u003cbr\u003eFactors\u003cbr\u003eK - Factor7\u003cbr\u003e    1.65\u003cbr\u003ee - ISO Factor8\u003cbr\u003e    0.35\u003cbr\u003eY - ISO Factor9\u003cbr\u003e    1.69\u003cbr\u003eG1 - Heat Generation Factor (Roller-Raceway)\u003cbr\u003e    42\u003cbr\u003eG2 - Heat Generation Factor (Rib-Roller End)\u003cbr\u003e    15.7\u003cbr\u003eCg - Geometry Factor10\u003cbr\u003e    0.0859\u003cbr\u003e\u003c\/p\u003e","brand":"TIMKEN","offers":[{"title":"Default Title","offer_id":55318656254333,"sku":"387A\/382A-TIMKEN","price":62.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/9684\/2842\/files\/90707.jpg?v=1713315496","url":"https:\/\/bearing-king.co.uk\/products\/387a-382a-timken-tapered-roller-bearing-5715x9684x21mm","provider":"Bearing King","version":"1.0","type":"link"}
