The rollers of these bearings are essentially cylindrical in shape providing modified line contact with the cylindrical inner and outer rings raceways. The rollers are accurately guided by ground ribs on either the inner ring or the outer ring, thus making these bearings suitable for heavy radial loads and high speed operations. For best results, these bearings should be accurately aligned.
The cylindrical shape of the rollers allows the inner ring to have considerable axial movement relative to the outer ring except for the bearings with the prefix "NH". This feature is valuable in accomodating thermal expansion in applications where both the inner and outer ring must be press-fitted. Since the inner and outer rings can be seperated from each other, the assembly of equipment is frequently facilitated.
