ARB Cylindrical Roller Bearings Guide
Product Description
The American Roller Bearing AD4783DK four-row cylindrical roller bearing consists of inner and outer rings, four rows of cylindrical rollers, and robust cage assemblies. Its 1:12 tapered bore provides secure mounting on a matching tapered roll neck, while the four-row roller arrangement delivers high radial load capacity and rigidity under heavy loads. The precision internal design helps distribute loads evenly across the roller rows for stable and reliable operation. It is primarily designed for rolling mill applications, including work rolls and backup rolls in steel, aluminum, and other metal processing equipment requiring reliable radial support under heavy rolling loads.
