The NTN UKFL2 is a flanged unit that pairs a Y-bearing insert with a cast iron housing. Two bolts hold the housing in place, while set screws secure the insert to the shaft. This arrangement suits equipment that needs a supported rotating shaft with straightforward installation and alignment, such as conveyors, fans and mixers.
Break down the code UKFL2 like this: UK means the insert has a tapered bore and uses an adapter sleeve; FL stands for the two-bolt flange housing; and 2 is the size series. In a reference such as S(SM)-UKFL213AD1, the digits 213 set the bearing and housing size, while AD1 covers sealing and internal clearance options. Reading these parts correctly helps you order a replacement without mixing up variants.
These units show up in belt conveyors, bucket elevators, agitators, blowers and packaging lines, as well as in water treatment equipment, mills and construction machinery. Their compact shape and simple mounting make them a common choice when a shaft runs on two supports and needs to turn with minimal friction, including in dusty or moderately humid conditions.
Selection depends on shaft diameter, radial and axial loads, and the operating environment. The insert seal keeps contaminants out; in heavy dirt or water, add extra protection. Match internal clearance and lubrication to the rotation speed. When mounting, align the housings, then tighten the insert set screws on the shaft with a proper wrench—never strike the bearing.
Y-bearing insert units from different brands can be swapped if the key dimensions line up: shaft diameter, distance between flange holes, center height and locking method. If you change manufacturer, confirm the insert uses the same locking and sealing arrangement. MR Industrial Accessories LLC quotes the exact reference you specify and helps you check compatibility with your equipment.
