The NTN ARFU is a four-bolt flange housing that holds an insert bearing, used to support a rotating shaft on a flat surface. It fits applications where the shaft runs at a right angle to the mounting plane and where moderate radial and axial forces are present. MR Industrial Accessories LLC supplies this line to plants and workshops across the United States and in several Latin American countries.

In the ARFU code, the letters indicate NTN's four-bolt flange housing family. The figure that comes after tells you the insert bearing size: ARFU-2S, for instance, takes a 15 mm shaft, and other references in the series handle larger diameters. The trailing S refers to the insert seal type, which holds grease in and keeps contaminants out. To pick the right unit, give us the complete part number or the shaft diameter.

You will find these housings on belt conveyors, mixers, fans, packaging equipment and process lines in food, chemical and materials operations. The four-bolt flange bolts rigidly to sheet metal or structural profiles, and alignment with the shaft is straightforward. In grain handling, aggregate processing and maintenance shops, they are a common replacement for worn units.

Selection depends on three things: shaft diameter, the type of load and the surrounding conditions. The S seal works well where dust or splashing is present; for harsher environments, consider other sealing options. When mounting, set the flange on a clean, flat surface, tighten the bolts in a cross pattern and confirm the shaft turns freely. Lubricate the insert according to the duty cycle and the grease recommended for the bearing.

ARFU housings from NTN can replace four-bolt flange units from other makers if the flange dimensions, shaft diameter and insert locking method all line up. A similar part number alone is not proof; compare the drawings. If you only have another brand's reference or an unmarked part, send it over and we will identify the matching equivalent.

To get the ARFU housing for your equipment, send the part number or shaft size by WhatsApp or email to MR Industrial Accessories LLC. We will quote the exact reference and help you mount and lubricate it correctly. We serve customers throughout the United States and Latin America and respond promptly.
