This Sealmaster TFT standard-duty flange unit has a cast iron housing with two bolt holes, contact seals, and Skwezloc collar. It is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The housing has machined foot pads and is made of solid cast iron for rigidity and vibration damping. Its close bolt holes and raised back faced make it suitable for air handling applications. It is equipped with a grease fitting on the outer surface for reapplying lubricant. The double-sealed, deep-groove ball bearing cartridge insert in the housing is rated "standard duty" for applications with moderate radial loads and light to moderate thrust or combination loads. The bearing is made of vacuum degassed 52100 chrome steel, and the inner and outer races are coated with black oxide for corrosion resistance. The inner ring is extended to provide extra shaft support. A pin and dimple anti-rotation 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. Nitrile rubber single-lip 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 a fluoropolymer-coated concentric locking clamp collar (Skwezloc) and two Torx head cap screws for 360-degree holding power. This lock type reduces vibration, does not mar the shaft, and is suitable for high-speed applications where the shaft rotates in a single or reversing direction. Flanged bearing units are suitable for use in industrial and commercial applications including conveyors, fans and blowers, construction machinery, and processing equipment, among many others.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
