The NTN UKFL2 Y-bearing insert flange unit is a two-bolt flange unit that combines an insert bearing with a cast iron housing. It is used to support rotating shafts in equipment where quick mounting and simple alignment are required, such as conveyor belts, fans or mixers. Its design allows the bearing to be fixed to the shaft with set screws and the housing to be mounted with two bolts, which simplifies assembly and replacement in the plant.
The designation UKFL2 reads as follows: UK indicates an insert bearing with tapered bore and adapter sleeve; FL corresponds to the two-bolt flange housing; and 2 identifies the size series. In the example S(SM)-UKFL213AD1, the number 213 defines the size of the bearing and housing, while AD1 indicates sealing and internal clearance variants. Knowing these suffixes helps you order the correct replacement without confusion.
In Argentine industry, these units appear in belt conveyors, bucket elevators, agitators, blowers and packaging lines. They are also found in water treatment equipment, mills and construction machinery. Being compact and easy to mount, they are common where a shaft must be supported with two supports and rotation maintained with low friction, even in environments with dust or moderate humidity.
To select the unit, take into account the shaft diameter, radial and axial loads, and environmental conditions. The insert seal protects against contaminants; if there is a lot of dirt or water, additional protection is advisable. Internal clearance and lubrication must be suitable for the rotation speed. During mounting, align the housings and tighten the insert set screws on the shaft with the appropriate wrench, without striking the bearing.
Y-bearing insert units are interchangeable between brands if the main dimensions match: shaft diameter, distance between flange holes, center height and fixing type. When changing manufacturer, verify that the insert has the same locking and sealing system.
