   The HPS cage incorporates a roller guide function in place of a guide ring. Eliminating the guide ring and optimizing the design of the inner and outer ring configuration facilitates the placement of additional, larger rollers. Optimized design for the internal specifications and improved press technology greatly increase load capacity, and realize longer life. Special surface treatment further strengthens the cage, reducing wear, heat and friction; it also allows for higher limiting speeds.  HPS spherical roller bearings are made from NSK’fs highcleanliness Z steel. This steel features greater fatigue strength. In addition, special surface treatment makes it more resistant to wear and more durable in a variety of applications.  By utilizing the space gained from eliminating the guide ring and improving the design through structural analysis, cage strength has been increased dramatically. The high-precision roller guide function in place of the guide ring, united with a special surface treatment, strengthens the cage against wear and increases the limiting speeds.  As global leaders in the bearing industry, we have continually invested in developing and refining our manufacturing technology and quality control procedures so that we are able to manufacture bearings of exceptional quality and accuracy. |
