This UCF204-12 bearing has a cast iron flange housing, four bolt holes, and a 3/4" inside diameter. This ready-to-mount unit requires four 3/8" mounting bolts (sold separately). It has chrome steel bearings and is designed for efficient operation at a wide range of speeds. The bearing has a dynamic (radial) load rating of 12.8 kN and a static (axial) load rating of 6.65 kN. The unit is secured to the shaft with set screws to prevent slippage. This bearing is most commonly used in mechanical equipment with moderate loads and shaft speeds and where the shaft and mounting surface are perpendicular to each other.
Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.
