The NSK AELPF series is a 3-bolt flange housing with an insert bearing, intended for mounting shafts on flat surfaces where a compact and secure fixing is needed. It appears in power transmission, conveying and general machinery. MR Industrial Accessories LLC supplies this NSK line to customers in the United States and Latin America, and quotes the exact code you request by WhatsApp or email.
The code starts with the AELPF prefix, which identifies a 3-bolt flange unit with an insert bearing. The number that follows gives the nominal shaft diameter: AELPF201W3 is for a 12 mm shaft, AELPF202W3 for 15 mm, AELPF203W3 for 17 mm and AELPF204W3 for 20 mm. Codes written with a hyphen, such as AELPF201-008W3 or AELPF202-009W3, point to inch or special sizes. The W3 suffix marks a particular insert configuration, usually related to the seal and lubrication.
These units are found on belt conveyors, packaging lines, mixers, blowers, centrifugal pumps and production equipment in food, chemical and materials plants. The 3-bolt flange lets you mount on sheet metal or profiles without extra machining, which is why they are also used on agricultural equipment and industrial ventilation systems exposed to weather and contamination.
When selecting a unit, check the shaft diameter, the load type (radial, axial or combined) and the working environment. The insert seal sets the level of protection against dust and moisture; suffixes such as W3 generally indicate contact seals with tighter sealing. At mounting, the flange must sit fully on a flat surface and the three bolts should be tightened evenly to prevent distortion. Use the lubricant specified for the insert, and in damp locations choose greases with corrosion inhibitors.
Insert bearing housing units are interchangeable between brands on main dimensions when the series and shaft diameter match. If you send us a code from another brand, we can identify a compatible equivalent. The NSK AELPF series is recognized by its 3-bolt flange and insert locking method, which may be set screw or eccentric. On replacement, confirm the flange shape and shaft diameter to keep the unit running correctly.
