This Browning VF2S-110 CTY intermediate-duty flange unit has a cast iron housing with two bolt holes, contact seal, and setscrew lock. It is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The housing has a semi-solid base to provide mounting stability and is made of cast iron for rigidity and vibration damping. The double-sealed, deep-groove radial ball bearing insert in the housing is made of 52100 chromium steel and is rated "intermediate duty" for applications with moderate radial loads and light thrust or combination loads. For increased shaft support and holding power, the bearing has an extended inner ring and a zone-hardened inner race. A rivet on the outer ring prevents rotation of the ring in the housing, reducing heat buildup and prolonging the bearing life. This self-aligning bearing has a convex sphered outer surface that compensates for misalignments, and honed races for quiet operation. Contact seals on both sides of the bearing retain lubricant applied at manufacture and help protect against contaminants. The bearing locks onto the shaft with two setscrews spaced 120 degrees apart for a three-point contact hold. This lock type minimizes ring distortion and vibration and is suitable for low to moderate speed applications where the shaft rotates in a single or reversing direction. A plug in the lubrication hole seals in lubricant that lasts the lifetime of the bearing. The plug also properly positions the anti-rotation lock pin.
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.
