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    555\u003cbr\u003eCone Part Number\u003cbr\u003e    559\u003cbr\u003eCup Part Number\u003cbr\u003e    552A\u003cbr\u003eDesign Unit\u003cbr\u003e    Inch\u003cbr\u003eCage Material\u003cbr\u003e    Stamped Steel\u003cbr\u003eDimensions\u003cbr\u003ed - Bore\u003cbr\u003e    2 1\/2 in 63.500 mm\u003cbr\u003eD - Cup Outer Diameter\u003cbr\u003e    4-7\/8 in 123.825 mm\u003cbr\u003eB - Cone Width\u003cbr\u003e    1.4440 in 36.678 mm\u003cbr\u003eC - Cup Width\u003cbr\u003e    1.1875 in 30.163 mm\u003cbr\u003eT - Bearing Width\u003cbr\u003e    1.5000 in 38.100 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    0.130 in 3.30 mm\u003cbr\u003eda - Cone Frontface Backing Diameter\u003cbr\u003e    2.95 in  75mm\u003cbr\u003edb - Cone Backface Backing Diameter\u003cbr\u003e    3.19 in 81 mm\u003cbr\u003eDa - Cup Frontface Backing Diameter\u003cbr\u003e    4.60 in 116.10 mm\u003cbr\u003eDb - Cup Backface Backing Diameter\u003cbr\u003e    4.29 in 108.97 mm\u003cbr\u003eAb - Cage-Cone Frontface Clearance\u003cbr\u003e    0.08 in 2 mm\u003cbr\u003eAa - Cage-Cone Backface Clearance\u003cbr\u003e    0.07 in 1.8 mm\u003cbr\u003ea - Effective Center Location3\u003cbr\u003e    -0.37 in -9.4 mm\u003cbr\u003eBasic Load Ratings\u003cbr\u003eC90 - Dynamic Radial Rating (90 million revolutions)4\u003cbr\u003e    13200 lbf 58600 N\u003cbr\u003eC1 - Dynamic Radial Rating (1 million revolutions)5\u003cbr\u003e    50800 lbf 226000 N\u003cbr\u003eC0 - Static Radial Rating\u003cbr\u003e    55700 lbf 248000 N\u003cbr\u003eCa90 - Dynamic Thrust Rating (90 million revolutions)6\u003cbr\u003e    7810 lbf 34700 N\u003cbr\u003eFactors\u003cbr\u003eK - Factor7\u003cbr\u003e    1.69\u003cbr\u003ee - ISO Factor8\u003cbr\u003e    0.35\u003cbr\u003eY - ISO Factor9\u003cbr\u003e    1.73\u003cbr\u003eG1 - Heat Generation Factor (Roller-Raceway)\u003cbr\u003e    91\u003cbr\u003eG2 - Heat Generation Factor (Rib-Roller End)\u003cbr\u003e    21.1\u003cbr\u003eCg - Geometry Factor10\u003cbr\u003e    0.111\u003cbr\u003e\u003c\/p\u003e","brand":"TIMKEN","offers":[{"title":"Default Title","offer_id":55330197799293,"sku":"559\/552A-TIMKEN","price":160.0,"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\/559-552a-timken-tapered-roller-bearing-635x12383x381mm","provider":"Bearing King","version":"1.0","type":"link"}
