The AELFD housing is a 4-bolt flange mounted bearing unit: a cast iron housing with an insert bearing that comes pre-assembled, lubricated and ready to bolt on. It is used to support transmission shafts in equipment where a mounting flange with good rigidity and load distribution is required. MR Accesorios Industriales sells the NSK line and quotes it by WhatsApp with the exact part number.

The series designation is read in blocks. AELFD identifies the 4-bolt flange unit with insert bearing from the NSK line; the number that follows is the size, and the suffixes indicate part variants. Two forms appear in the examples: AELFD201W3 and AELFD201-008W3. The first is the basic size of the series; the second, with a hyphen, corresponds to a shaft diameter in inches. The W3 suffix indicates the unit variant. To request a quote, send us the complete part number exactly as it appears on the equipment.

In Argentine industry these housings appear in belt conveyors, packaging lines, mixers, blowers, centrifugal pumps and milling lines. The 4-bolt flange allows them to be fastened to sheet metal or profile structures, with the shaft at 90° to the mounting surface. They are chosen when the support needs rigidity and even load distribution over the structure, and when replacement must be resolved without disassembling the whole assembly.

To select correctly, start from the shaft diameter and the mounting type; then check the sealing, because the insert may come with a contact seal or a lip seal depending on the environment. During mounting, rest the flange on a flat, clean surface, tighten the four bolts in a cross pattern and check shaft alignment before start-up. The insert lubrication comes from the factory; in service, follow the equipment's greasing plan and inspect the seal if there is dust or water.

4-bolt flange units are interchanged between brands by shaft number and housing type, not by the manufacturer's part number. If the customer brings an unidentified part or another brand's part number, at MR Accesorios Industriales we indicate the compatible alternative and quote it. We can also verify the sealing variant and the mounting type before giving you the quote.
