The ZUCNFL housing is a 2-bolt flange mounted bearing unit: it combines a cast iron housing with an insert roller or ball bearing, already mounted and lubricated. It is used to support shafts on flat structures, with front mounting and two fastening points.

The designation ZUCNFL reads as follows: ZUCNFL identifies the 2-bolt flange housing family with insert bearing; the digits that follow indicate the shaft diameter. For example, ZUCNFL204 corresponds to a 20 mm shaft, ZUCNFL205 to 25 mm and ZUCNFL206 to 30 mm. Hyphenated suffixes, such as ZUCNFL204-12, ZUCNFL205-16 or ZUCNFL206-18, indicate inch sizes: 3/4", 1" and 1-1/8" respectively. The complete part number gives you the diameter and the fastening type.

These housings are used in conveyors, belts, elevators, mixers, fans and process lines where the shaft runs parallel to a sheet metal or structure. In Argentina they appear in food, cement, grain, tannery and metalworking plants. The 2-bolt flange allows mounting on flat surfaces with aligned holes, and the insert accommodates slight misalignment inherent to mounting. It is a robust solution for shafts rotating at moderate speeds with radial loads and some axial load.

To choose correctly, check the shaft diameter, the insert fastening type (set screw, eccentric or adapter) and the sealing: standard units have contact seals that retain grease and block dust. In environments with water or fine dust, additional protection is advisable. During mounting, rest the flange on a clean, flat surface, tighten the bolts in a cross pattern and check that the shaft turns without effort. The insert is lubricated from the factory; in service it is relubricated according to the duty cycle.

Mounted bearing units are interchangeable between brands if the shaft diameter, hole spacing, bolt diameter and center height match. NTN, SKF, FAG, NSK and other brands use their own nomenclature, but standardized dimensions allow direct replacements. If you have another brand's part number or an unidentified part, send us the main dimensions and we will indicate the compatible equivalent.
