LINK-BELT 300 series 4-bolt flange housings are mounted units that combine an insert bearing with a circular flange housing, designed to secure drive shafts to walls, frames or metal structures. They are used when the shaft must be perpendicular to the mounting surface and rigid support with four anchor points is required. MR Accesorios Industriales supplies this line backed by more than 80 years in the industry.

The FU designation followed by three digits identifies the size and configuration of the unit: for example, FU314, FU315 and FU316 correspond to increasing shaft diameters within the 300 series. The number does not indicate the diameter directly, but refers to a standardized dimension table. Any suffixes that may appear after the number refer to sealing variants, insert locking type or housing material. To choose the correct part number, the most practical approach is to start from the required shaft diameter and consult the equivalence table.

These housings are used in belt conveyors, bucket elevators, mixers, agitators, centrifugal pumps and industrial fans. In food, chemical and aggregate processing plants, the 4-bolt flange allows the shaft to be mounted on structural steel without machining a housing. They are also found in washing equipment, dryers and machinery for the wood and cement industries, where the robustness of the housing and the ease of replacing the insert are key to reducing downtime.

To select correctly, verify the shaft diameter, the expected radial and axial load, and the type of sealing according to the environment: dust, moisture or pressure washing. Installation requires that the support surface be flat and aligned perpendicular to the shaft; otherwise, the insert operates misaligned and its service life is shortened. Lubrication of the insert bearing is usually permanent, but in severe applications a grease point should be provided. The insert is locked to the shaft with set screws or a taper bushing, depending on the model.

LINK-BELT is a recognized brand in the Argentine market and its 300 series flange housings are in many cases interchangeable with those of other brands that use the same three-digit nomenclature. That compatibility is not universal: before replacing a unit, compare the shaft diameter, the distance between flange holes and the insert type. MR Accesorios Industriales can indicate the compatible alternative or, if it is not available, we manufacture it to measure. Interchangeability between brands is common in this family, but the critical dimensions must always be validated.

If you need a 4-bolt flange housing for your equipment, send the part number or shaft diameter by WhatsApp to MR Accesorios Industriales. We will quote it promptly and, if the exact model is not available, we offer the equivalent option or special manufacturing. With more than 80 years of experience, at MR Accesorios Industriales we know the applications of these housings in Argentine industry and help you resolve the replacement without hassle.
