The NSK ASFD is a bearing unit that combines an insert bearing with a cast iron housing shaped as a four-bolt flange. The flange is the anchoring surface, so the unit bolts to a flat face and supports a rotating shaft. This arrangement suits equipment that needs secure fastening with straightforward installation.

In the ASFD code, the letters identify a four-bolt flange unit of that series. The digits that follow correspond to a metric shaft size. A hyphenated suffix marks a variant, often an inch shaft dimension or a different mounting detail. Provide the complete part number and we will quote the assembled unit.

Typical applications include conveyors, belts, agitators, blowers, centrifugal pumps and other process equipment. The four-bolt flange lets you fasten the unit to a flat surface and align the shaft, which helps when the housing sits on folded sheet metal or profile structures.

For selection, confirm the shaft diameter and the mounting type. Insert bearings are available with set screws or an eccentric collar; seals may be single or double contact. At installation, place the flange on a clean, flat surface, tighten the four bolts in a cross pattern and verify that the shaft turns freely. Follow the duty cycle for lubrication and check alignment to prevent side loads.

Four-bolt flange units from different brands can interchange when the shaft diameter, bolt circle diameter and center distance match. An NSK ASFD part number may be replaced by an equivalent unit with the same configuration. If you send the original part or another brand's number, we will identify the compatible alternative and quote it.

To proceed, send the full part number or the shaft and flange dimensions via WhatsApp or email. We will quote the NSK unit you need and reply promptly.
