Roller Bearing for Sheaves - Sealed, NAS Series
- Volume Discount
IKO Roller Bearings are heavy duty bearings with rollers incorporated in a double row. They are non-separable bearings with a high load rating. They can withstand not only radial loads but axial loads as well, which are supported at the contacts between the shoulders of the inner and outer rings and the end faces of the rollers. They should be used at the fixing side of a shaft. Like needle roller bearings, they are also compact. Roller bearing types include: caged, full complement and the type for sheaves, and they can be selected based on the operating conditions. These bearings are used in heavy-duty machinery such as construction equipment, and industrial machines.
