Koyo configuration of double row circular cone roller bearings basic performance requirements

, usually composed of two double row circular cone roller bearings radial and axial support, and on one side of the bearing is known as the fixed end bearing, it suffered two fixed shaft radial and axial load type and the function of the relative axial displacement of bearing box. The other will be known as the free end, only bear radial load, axial relative motion can be. Fixed end double row circular cone roller bearings must be compared with the fixed shaft and bearing box, a more suitable bearing can withstand, but installation must keep certain radial bearing box interval. Due to the free end of koyo bearing axial length change of thermal expansion, double row taper roller bearings is not going to happen. Axial displacement occurs in the bearing ring, may also appear with bearing in the bearing. Koyo bearing basic performance requirements of materials depends on the working characteristics of double row circular cone roller bearings. In general, the bearing steel should have the following properties: 1. High contact fatigue strength. 2. High wear resistance. 3. High elastic limit and yield strength. 4. High and uniform hardness. 5. A certain amount of impact toughness. 6. Good dimensional stability. 7. Good corrosion inhibition. 8. Good process performance. Under the working conditions for special material of double row circular cone roller bearings, according to its specific requirements should also have its conditions appropriate to the special performance, such as: high temperature resistant, low temperature resistance, corrosion resistance, anti radiation, magnetic properties, etc.
