398-394AB TSF (Single Row Tapered Roller Bearings with Flange) (Imperial) consist of a tapered inner ring assembly and an outer ring. They have flanged outer rings so that the housing through-hole can be precisely aligned. 398-394AB bore dia is 2". Its out dia is 4.3307". 398-394AB roller material is Roller_Material. Its seal type is Open. The 398-394AB TSF (Single Row Tapered Roller Bearings with Flange) (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, 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.
