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    25500\u003cbr\u003eCone Part Number\u003cbr\u003e    25577\u003cbr\u003eCup Part Number\u003cbr\u003e    25521\u003cbr\u003eDesign Unit\u003cbr\u003e    Inch\u003cbr\u003eCage Material\u003cbr\u003e    Stamped Steel\u003cbr\u003eDimensions\u003cbr\u003ed - Bore\u003cbr\u003e    1.6880 in 42.875 mm\u003cbr\u003eD - Cup Outer Diameter\u003cbr\u003e    3.2700 in 83.058 mm\u003cbr\u003eB - Cone Width\u003cbr\u003e    1.0000 in 25.400 mm\u003cbr\u003eC - Cup Width\u003cbr\u003e    0.7500 in 19.050 mm\u003cbr\u003eT - Bearing Width\u003cbr\u003e    0.9376 in 23.815 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    1.93 in 49 mm\u003cbr\u003edb - Cone Backface Backing Diameter\u003cbr\u003e    2.17 in 55 mm\u003cbr\u003eDa - Cup Frontface Backing Diameter\u003cbr\u003e    3.05 in 77.00 mm\u003cbr\u003eDb - Cup Backface Backing Diameter\u003cbr\u003e    2.83 in 71.88 mm\u003cbr\u003eAb - Cage-Cone Frontface Clearance\u003cbr\u003e    0.06 in 1.5 mm\u003cbr\u003eAa - Cage-Cone Backface Clearance\u003cbr\u003e    0.01 in 0.3 mm\u003cbr\u003ea - Effective Center Location3\u003cbr\u003e    -0.25 in -6.4 mm\u003cbr\u003eBasic Load Ratings\u003cbr\u003eC90 - Dynamic Radial Rating (90 million revolutions)4\u003cbr\u003e    5270 lbf 23500 N\u003cbr\u003eC1 - Dynamic Radial Rating (1 million revolutions)5\u003cbr\u003e    20300 lbf 90500 N\u003cbr\u003eC0 - Static Radial Rating\u003cbr\u003e    24900 lbf 111000 N\u003cbr\u003eCa90 - Dynamic Thrust Rating (90 million revolutions)6\u003cbr\u003e    3020 lbf 13500 N\u003cbr\u003eFactors\u003cbr\u003eK - Factor7\u003cbr\u003e    1.74\u003cbr\u003ee - ISO Factor8\u003cbr\u003e    0.33\u003cbr\u003eY - ISO Factor9\u003cbr\u003e    1.79\u003cbr\u003eG1 - Heat Generation Factor (Roller-Raceway)\u003cbr\u003e    35.2\u003cbr\u003eG2 - Heat Generation Factor (Rib-Roller End)\u003cbr\u003e    14.3\u003cbr\u003eCg - Geometry Factor10\u003cbr\u003e    0.0801 \u003cbr\u003e\u003c\/p\u003e","brand":"TIMKEN","offers":[{"title":"Default Title","offer_id":55318314811773,"sku":"25577\/25521-BKL","price":52.85,"currency_code":"GBP","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\/25577-25521-timken-tapered-roller-bearing-42875x8306x2381mm","provider":"Bearing King","version":"1.0","type":"link"}
