A UKC unit from NTN pairs a circular-flange cast iron housing with a UK insert bearing, giving you a cartridge-style support for rotating shafts fastened to a fixed frame. It keeps the shaft aligned, shields the bearing from its surroundings and installs without a complex housing bore. Maintenance and purchasing teams use these units on industrial drive and conveyor equipment where a firm support and straightforward fitting are what matter.

Reading the code helps you order the right replacement. The letters UK point to an insert bearing that mounts with a taper sleeve, while C stands for the cartridge housing shape with its circular flange. The digits after that letter group give the shaft size in inches or the matching metric figure, and a D1 suffix marks a variant in sealing and internal design. So UKC205D1 fits a 25 mm shaft, UKC206D1 a 30 mm shaft and UKC207D1 a 35 mm shaft, continuing upward in the same pattern. Shafts from 20 to 45 mm fall in the UKC2 series, and 50 to 65 mm in the UKC3 series.

Typical installations include belt conveyors, bucket elevators, mixers, mills, conveyor belts and process lines in the food, chemical, cement and mining sectors. The gray cast iron housing with its circular flange bolts to sheet metal or welded structures through two or four mounting holes. Because the insert bearing rides on a taper sleeve, it slides onto the shaft easily and tolerates slight misalignment.

When specifying a unit, look at shaft diameter, the radial and axial loads involved and the conditions on site. Sealing in the UK insert uses nitrile or polyurethane, which keeps dust and moisture away from the rolling elements; where water or frequent washdowns are present, confirm how well the seal holds up. A lock nut secures the taper sleeve and should be tightened to the recommended torque. General-purpose lithium grease handles lubrication, and the bearing's internal clearance is set at the factory. Line the flange up with the shaft so no unnecessary stress enters the unit.

NTN UKC housings swap with units from other makers that use the same cartridge standard, such as SKF, FAG or NSK, provided the series and shaft diameter line up. Flange dimensions and hole patterns are generally compatible across manufacturers, though checking outer diameter and total width before a replacement is worthwhile. A worn shaft can prevent the taper sleeve from seating properly; in that case, inspect the shaft or ask about another option.
