Ball Bearing Units (contents)

1 Structure and features FYH Ball Bearing Units are manufactured to exacting standards comprising grease sealed deep groove ball bearings and housings in various forms. Self-aligning units allow for easy installation and are supplied with grease fittings in order to facilitate quick and convenient re-lubrication. 1.1 Structure FYH Ball Bearing Units are constructed of high-carbon chromium bearing steel and have precision honed raceways and riveted steel cages (Fig. 1.1). Grease fitting Outer ring with spherical outside surface Grease hole Slinger Seal Ball and cage Wide inner ring Hexagon...

1 Structure and features 3 Superior sealing performance 1.2 Features FYH Ball Bearing Units have many features and are available in various models. A wide selection of mounted units is offered to fit virtually any application. 1 Supreme load capacity and accuracy FYH Ball Bearing Units feature an internal structure identical to single row deep groove ball bearings can and bear significant radial load, as well as a great deal of axial load in both directions. The hardened steel balls exhibit a high degree of “roundness” and the races are highly polished to accommodate a smooth ride at a wide...

4 Simple lubrication FYH Ball Bearing Units are tapped to accept a grease fitting which is also supplied with every mounted unit. Bearings are pre-lubricated at the factory and do not require additional grease upon installation. When operating in excessively moist, dusty, or hot environments it is recommended that grease be supplied at regular intervals. If appropriately maintained, the rated life of the bearing can be extended. The grease fittings that are supplied with FYH mounted units include 1/4-28 for smaller units and 1/8 PT for larger units. Additional styles are available upon...
