Determining the best pattern of double row cylindrical roller bearing

Cylindrical Roller bearings are designed to carry heavy radial loads. The rollers are guided by ribs on either the inner or outer ring; therefore these bearings are also suitable for high speed applications. Furthermore, cylindrical roller bearings are separable, and relatively easy to install and disassemble even when interference fits are required. The load carrying capacity of a single row roller bearing is less than that of a double row roller bearing. An improvement in load distribution and thus load carrying capacity may be realized, as well as contact stress is also reduced. The contact stress of two patterns of double row cylindrical roller bearings evaluated by the Hertzian Contact stress theory and then by finite element analysis. The validation of Finite Element method and determining the best pattern by considering stress & fatigue life parameter.
