FNL flanged housings

The SKF FNL housing is a one-piece flanged housing, made of cast iron, that is bolted to a wall or vertical frame. It houses spherical ball and roller bearings with tapered bore, mounted on the shaft with an adapter sleeve. It is selected by bearing size, shaft diameter, mounting method to the structure, and load and speed conditions.

In SKF codes such as FNL 505 A, FNL 506 B or FNL 507 A, the FNL acronym identifies the series, the number corresponds to the housing size and the bearings it accepts, not the shaft diameter, and the final letter (A or B) distinguishes execution variants. Two housings with the same number may not be interchangeable, so it is quoted with the complete code.

These housings are used in belt conveyors, fans, pumps, and other equipment where the shaft is supported on a structure and the bearing must be fixed precisely. They are complemented with sealing covers and locating rings that close the housing and protect it from dust and moisture, according to the axial position required by the mounting.

In this subcategory we work with SKF. To request a quote, send us via WhatsApp the complete code or, if you are replacing a part, the shaft diameter, bearing, distance between mounting holes, and a photo of the housing. We will quote it together with the covers and accessories that complete the assembly.
