30204 TS (Single Row Tapered Roller Bearings) (Metric) consist of a tapered inner ring assembly and an outer ring. 30204 bore dia is 20 mm. Its out dia is 47 mm. 30204 roller material is Roller_Material. Its seal type is Seal_Bearing. The 30204 TS (Single Row Tapered Roller Bearings) (Metric) can bear both radial and axial loads with ease and provides low friction during operation even under the most severe conditions.
Mining machines, rolling mills, metallurgy, hydraulic generators, vertical generators, propeller shafts for ships, tower cranes, extruders, gear systems and transmissions, transport vehicles, port tower crane equipment, machine tool spindles, gear reducers, automobile drives, Aircraft wheels, agricultural wheels, tensioning rollers, rakes, construction and mining equipment, railway axles – etc.
Several factors must be considered for choosing tapered roller bearings. These factors include the roller material, design, shields and seals, cage, Annual Bearing Engineering Committee (ABEC) grade, radial clearance, and lubricant, etc.
