48290 – 200809 22 Timken Tapered Roller Bearing Cone 48290 NEW IN BOX 5″ BORE US
48290 – 200809 22 Timken Tapered Roller Bearing Cone 48290 NEW IN BOX 5″ BORE This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). It is typically mounted in opposing pairs on a shaft.Unit of Measure Imperial Metric Both Specifications | Dimensions | Abutment and Fillet Dimensions | Basic Load Ratings | FactorsSpecificationsSeries48200Cone Part Number48290Design UnitsImperialCage TypeStamped SteelC1 – Dynamic Radial Rating (Two-Row, 1 million revolutions)1105000 lbf466000 NC90(2) – Dynamic Radial Rating (Two-Row, 90 million revolutions)227200 lbf121000 NDimensionsd – Cone Bore5 in127 mmB – Cone Width1.5000 in38.100 mmAbutment and Fillet DimensionsR – Cone Backface “To Clear” Radius30.14 in3.600 mmda – Cone Frontface Backing Diameter5.31 in135 mmdb – Cone Backface Backing Diameter5.55 in141 mmAb – Cage-Cone Frontface Clearance0.15 in3.8 mmAa – Cage-Cone Backface Clearance0.06 in1.5 mma – Effective Center Location4-0.22 in-5.6 mmBasic Load RatingsC90 – Dynamic Radial Rating (90 million revolutions)515600 lbf69400 NC1 – Dynamic Radial Rating (1 million revolutions)660200 lbf268000 NC0 – Static Radial Rating111000 lbf493000 NCa90 – Dynamic Thrust Rating (90 million revolutions)78160 lbf36300 NFactorsK – Factor81.91G1 – Heat Generation Factor (Roller-Raceway)353G2 – Heat Generation Factor (Rib-Roller End)91.3Cg – Geometry Factor90.1141 Based on 1 x 106 revolutions L10 life, for the ISO life calculation method.2 Based on 90 x 106 revolutions L10 life, for The Timken Company life calculation method.
