Classification :
Tapered roller bearings
Key Words:
Tapered roller bearings
30203 TS (Single Row Tapered Roller Bearings) (Metric) consist of a tapered inner ring assembly and an outer ring. 30203 bore dia is 17 mm. Its out dia is 40 mm. 30203 roller material is Roller_Material. Its seal type is Seal_Bearing. The 30203 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.
Typical applications include
Gearing Systems and Transmissions, Thermal Power Coal Transporters, Port Equipment, Rubber and other Industrial applications, Machine Tool Spindles, Gear Reducer, Automotive Drive Axle, Aircraft wheels, Agricultural Wheels, Tensioning Roller, Raking Machine, Construction and Mining Equipment, Railroad Axle-box, etc.
General Selection Factors
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.
