The NSK AELS series is a ball bearing insert with an extended inner ring, made to sit inside split plummer block housings and pillow block units. It suits equipment where a simple rolling unit that is straightforward to align and swap out is what you need. MR Industrial Accessories LLC supplies this series to customers throughout the United States and in several Latin American countries, and quotes the exact part number you request by WhatsApp or email.

Reading the AELS designation is a matter of breaking it into blocks. The four letters mark the family: an insert bearing with an extended inner ring and set screw locking. What follows tells you the bore and the locking arrangement. Take AELS201-008NW3, which is an insert with a 1/2 inch bore, against AELS201NW3, the metric version at 12 mm. The NW3 suffix covers the sealing and cage characteristics. Other sizes follow the same pattern, as AELS202-009NW3, AELS203-011NW3 and AELS204-012NW3 show.

You will find these inserts in conveyors, belts, elevators, mixers, fans and process equipment across food, chemical, cement and aggregate plants, as well as in agricultural machinery, packaging lines and material handling systems. They mount in split plummer block housings or in pillow block and flanged units. The advantage in service is that a worn insert can be exchanged on its own, leaving the housing in place.

Selection comes down to three things: shaft diameter, locking type and sealing. The AELS series locks with set screws on the extended inner ring, and the NW3 sealing handles dust and moderate moisture. At mounting, verify housing alignment and axial clearance, apply lithium grease or whatever grease the manufacturer specifies, then tighten the set screws onto the shaft without excess force so the ring is not deformed. Check tightness and seal condition on a regular basis.

If the part number you have comes from another brand, we can point you to the compatible equivalent in the AELS series. Bore diameter, inner ring width and locking type are what determine interchangeability between manufacturers, and with those figures we will quote the matching NSK insert. We can also help identify a part whose markings are no longer legible.
