The AELPF housing is a 3-bolt flange unit with insert bearing, designed to mount shafts on flat structures where compact and robust fastening is required. It is used in power transmission, conveying and general machinery equipment. MR Accesorios Industriales sells this NSK line in Buenos Aires, Argentina, and quotes it on WhatsApp with the exact code you need.
The AELPF designation is read as a 3-bolt flange unit with insert bearing of the AELPF series. The number following the prefix indicates the nominal shaft diameter: for example, AELPF201W3 corresponds to a 12 mm shaft, AELPF202W3 to 15 mm, AELPF203W3 to 17 mm and AELPF204W3 to 20 mm. Suffixes with a hyphen, as in AELPF201-008W3 or AELPF202-009W3, identify inch diameter or special size variants. The W3 suffix indicates a specific insert configuration, generally linked to the type of seal and lubrication.
These housings are used in belt conveyors, packaging lines, mixers, blowers, centrifugal pumps and production lines in food, chemical and materials plants. In Argentina they are common in the meat industry, flour mills and plastics factories, where the 3-bolt flange allows mounting on sheet metal or profiles without additional machining. They are also chosen in agricultural equipment and industrial ventilation systems for their resistance to weather and contamination.
To select the right housing, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert seal defines the protection against dust and moisture: suffixes such as W3 usually indicate contact seals with greater tightness. During mounting, make sure the flange rests fully on a flat surface and that the three bolts are tightened evenly to avoid deformation. Lubrication must be the one specified for the insert; in humid environments, choose greases with corrosion inhibitors.
Insert bearing housing units are interchangeable between brands in terms of main dimensions, as long as the series and shaft diameter match. If you bring us the code from another brand, we can tell you the compatible equivalent. The NSK AELPF series is distinguished by its 3-bolt flange and the insert locking system, which may vary in set screw or eccentric type. When replacing, verify the flange shape and shaft diameter to maintain correct operation.
