3/4" Bore - Locking Collar - Insert Bearing UC204-12

The UC204 axle insert mounted bearing is made of steel, has a 3/4" inside diameter, a 47mm outside diameter, an inner ring width of 31mm, an outer ring width of 16mm, and UC204 steel bearings for efficient operations at a wide range of speeds. The unit is mounted directly onto the shaft using set screws, so it does not require a connecting adaptor and mounting bolts. The bearing has a dynamic (radial) load rating of 12.8 kN and a static (axial) load rating of 6.65 kN. Insert bearings are most commonly used for small axles.

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.
