Timken E-4BF-TRB-1-7/16 Flanged Four-Bolt Bearing Unit

The Timken E-4BF-TRB-1-7/16 Flanged Four-Bolt Bearing Unit is a Type E mounted tapered roller bearing housed in a four-bolt flange cast-iron housing with an E-Coat finish, designed to support rotating shafts under combined radial and axial loads in demanding industrial environments. This unit integrates a precision tapered roller bearing into the housing and uses premium industrial grease, with a shaft size of 1-7/16 in (1.4375 in / 36.51 mm) and a four-bolt flange for secure mounting, enabling installation that tolerates misalignment, shock loads, and challenging operating conditions. Key specifications include a dynamic load rating (C90) of 6,100 lbf, a static load rating (C0) of 26,000 lbf, a maximum permissible thrust load of 2,590 lbf, a maximum slip-fit radial load of 5,000 lbf, and a maximum speed of 3,820 rpm; overall weight is approximately 7.0 lb (3.18 kg). Important dimensions are B 3.000 in, L 4.625 in, A 2.5938 in, J 3.500 in, with a bolt diameter of 0.500 in. Typical applications include conveyors, material handling systems, mining equipment, agricultural machinery, fans, crushers, and other industrial power transmission equipment, making it suitable for new installations, retrofits, and maintenance where reliable shaft support is required.
