TIMKEN TAPERED ROLLER BEARING E-4BF-TRB-80MM

TIMKEN TYPE E MOUNTED TAPERED ROLLER BEARING.

These ratings have been calculated for initial bearing selection . These include a nominal safety factor for the standard Type E two- and four-bolt pillow blocks . The following conditions apply: standard cast-iron material, the force is applied perpendicular to the shaft axis, and the housing bolts are properly clamped .     These limits should not be applied to operating conditions that include impact (shock) loads or combined radial and thrust loads that are not directed into the pillow block base .

If heavy cap loads are expected, use the following modifications to mounting method or equipment design: Grade 8 base bolts and hardened washers; ensure that proper installation torque is achieved and is uniform .

If axial loads are expected, provide mechanical stops or shear bars with strength sufficient to support the load . Specification of the strength, material, method of fastening, and precision location are the responsibility of the machinery designer .
