LL687949-LL687910 TS (Single Row Tapered Roller Bearings) (Imperial) consist of a tapered inner ring assembly and an outer ring. LL687949-LL687910 bore dia is 38.5". Its out dia is 44.5". LL687949-LL687910 roller material is Chrome Steel. Its seal type is Open. The LL687949-LL687910 TS (Single Row Tapered Roller Bearings) (Imperial) 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, Single Row 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.
