1 Structure and Features FYH Ball Bearing Units are manufactured to exacting standards comprising of 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 Double lip FloBack seal Ball and cage Wide inner ring...

3 Superior sealing performance FYH Ball Bearing Units efficiently prevent grease from leaking out of the interior of the bearing, and perform extremely well at keeping contaminates, such as dust and water, from entering. This is achieved by installing the seal to the outer ring of the bearing and installing the slinger to the inner ring of the bearing. The FloBack seal to be used in the standard FYH Ball Bearing units will contribute to the long life of the bearing. It consists of a double-lip seal which is stamped into place in the outer ring of the bearing to reduce the possibility of being...

5 Highly rigid and rugged cast iron housings FYH Ball Bearing Unit housings are designed so that they are optimized for reduction of deformation due to centralization of stress and load. Only the best material is selected to be cast by a highly advanced technique or press working technique, depending on the housing. Since any abnormal load on the bearing is eliminated by the housing, the life of the bearing can be extended. A Granular material baking finish coating (powder coating) helps resist corrosion and protect the surface of the housing for an extended period of time. FYH original solid...

2.2 High / Low Temperature Series (suffix codes - High temperature: D1K2 & D9K2, Low temperature: D2K2) For applications that require bearing units to be used at a higher or lower temperature range than our standard models FYH offers several options. For high temperature units that require lubrication please specify D1K2 as a suffix to the standard part number. For high temperature units that do not require lubrication specify D9K2. The D9K2 insert uses a fluoro-grease that allows for excellent heat resistance and operation with minimal maintenance. Specifications for the high temperature and...

2.2.1 Rotational speed adjustment due to shaft fit A marginal degree of clearance is typically used to facilitate easy installation of a bearing to a shaft. The amount of clearance between the bearing and shaft must be factored in to determine the maximum allowable rotational speed, and as rotational speed is increased, the amount of clearance must be decreased. Table 2.3 shows the factor that must be used to correct the allowable rotational speed. The maximum rotational speed is determined by multiplying the speed found in Table 6.1 by the factors below. Table 2.3 Fitting factor of ball bearing...
