Timken E-4BF-TRB-3 7 16 Tapered Roller Bearing

Timken E-4BF-TRB-3 7/16 is a Type E four-bolt flange mounted tapered roller bearing unit that delivers robust shaft support for equipment facing heavy combined radial and axial loads. Encased in a cast iron four-bolt square flange housing, it uses a single-row tapered roller bearing insert that provides high load capacity and precise shaft alignment, with grease lubrication and seals engineered to retain lubricant and block contaminants in demanding environments. Key specifications include a 3-7/16 in shaft size, housing bore 7.250 in, overall length 9.250 in, dimension B 5.000 in, flange width 4.500 in, bolt spacing 7.000 in, and bolt diameter 3/4 in. The unit employs double set screw collars for locking and features a 1/8 in NPT grease fitting. Rated dynamic load C90 19,600 lbf and static load C0 108,600 lbf, it accommodates up to 5,181 lbf of thrust and up to 16,000 lbf maximum slip radial load, with a maximum speed of 1,640 rpm. Commonly used in conveyors, mining and aggregate processing equipment, sawmills, lumber mills, agricultural machinery, bulk material handling systems, and other heavy industrial power transmission applications.
