The ARFU designation identifies NTN 4-bolt flange housings. The number that follows indicates the size: ARFU-1 and ARFU-2 are examples of this series. These part numbers let you select the right unit according to shaft diameter and required load capacity. When requesting a quote, the full part number speeds up identification of the exact part.
These housings are used in conveyors, agitators, fans, pumps and agricultural machinery, among other applications. In Argentina, they are common in food, chemical and aggregate processing plants, where robust mounting and easy maintenance are required. Their 4-bolt flange allows them to be fastened to flat surfaces with simple alignment.
To select the right housing, take into account the shaft diameter, radial and axial loads, and environmental conditions. The insert bearing usually comes pre-lubricated and with seals that retain grease and block contaminants. During mounting, make sure the surface is clean and flat, and tighten the bolts evenly to prevent distortion. Regular lubrication extends service life.
NTN ARFU housings can be interchanged with units from other brands that follow the same 4-bolt flange standard, such as SKF, FAG or NSK. If you have another brand's part number, we can tell you the compatible equivalent. Always verify the critical dimensions and the mounting type before replacing a unit.
