NACHI H-L44643R/10 Tapered Roller Bearing, 25.4 mm Dia Bore, 50.292 mm OD, 1 Row, 14.224 mm W, 31200 N Dynamic/37000 N Static Load
A tapered roller bearing consists of a cone (or inner ring), the cup (or outer ring), tapered rollers and a cage. The tapered rollers allows the bearing to handle a combination of heavy radial and thrust loads. The bearings are separable. Internal clearance is established during mounting by the axial positioning of the cone relative to the cup. Preloading this bearing can obtain a higher rigidity and better running accuracy to optimize performance. They are used mostly for heavy duty, moderate speed applications. These bearings are generally used in pairs and are most common on agriculture, construction and mining equipment, vehicle and trailer axles and in gear boxes.
