IKO Shell Type Needle Roller Bearing | AIMS Industrial

About Structure and Features

• Inner rings are heat-treated and finished by grinding to a high degree of accuracy.
• In the case of needle roller bearings, normally, the shafts are heat-treated and finished by grinding, and used as the raceway surfaces.
• However, when it is impossible to make shaft surfaces according to the specified surface hardness or surface roughness, inner rings are used.
• Inner rings include those for Shell Type Needle Roller Bearings and those for general use and are available in a variety of dimensions.
• When shafts move axially or seals are used adjacent to bearings, wide inner rings can be selected.
• Inner rings can also be used economically as bushings without requiring any additional machining
