The AELFD series from NSK is a 4-bolt flange mounted bearing unit. It consists of a cast iron housing and an insert bearing, supplied already assembled and lubricated so it can be bolted into place. This configuration supports transmission shafts where the mounting surface needs to be rigid and distribute load evenly. MR Industrial Accessories LLC supplies the NSK line and provides quotes when you send the exact part number by WhatsApp or email.

The part number is built in sections. AELFD denotes the 4-bolt flange unit with insert bearing; the digits that follow indicate the size, and any suffixes show the variant. You will see two formats: AELFD201W3 and AELFD201-008W3. The first is the basic size; the second, with a hyphen, refers to an inch shaft diameter. W3 is the variant suffix. For a quote, provide the full part number as it appears on the equipment.

These units are common in belt conveyors, packaging lines, mixers, blowers, centrifugal pumps and milling equipment. The 4-bolt flange mounts to sheet metal or profile structures and positions the shaft at 90° to the mounting surface. They are selected when the support requires rigidity and even load distribution, and when replacement should be possible without dismantling the entire assembly.

Selection starts with the shaft diameter and mounting type. Then check the sealing, because the insert may have a contact seal or a lip seal depending on the environment. During installation, place the flange on a flat, clean surface, tighten the four bolts in a cross pattern and verify shaft alignment before start-up. The insert is factory-lubricated; in service, follow the equipment's greasing schedule and inspect the seal if dust or water is present.

4-bolt flange units interchange between brands by shaft number and housing type, not by manufacturer part number. If you have an unidentified part or another brand's number, MR Industrial Accessories LLC can identify the compatible alternative and quote it. We can also confirm the sealing variant and mounting type before quoting.
