By taking full advantage of NSK’s wealth of experience and expertise, HPS spherical roller bearings realize unprecedented endurance and high limiting speeds to support downsizing while at the same time improving performance and lengthening equipment operating life. Just what you would expect from NSK, the leading bearing company. High performance in diverse applications with reduced maintenance costs and more compact design Lower Maintenance Cost Maintenance costs are an important factor in reducing total equipment costs. HPS spherical roller bearings realize twice the operating life of conventional products, and longer operating life leads to lower maintenance costs. Contributing to equipment downsizing Achieving longer operating life can be realized together with the selection of smaller bearings. HPS spherical roller bearings allow compact design for various equipment, thereby supporting the demand for downsizing. Applicable to a variety of applications With improved cage resistance to wear at higher speeds over longer period of operation, HPS spherical roller bearings deliver high performance to a variety of applications. Long Life Flexible Compact 4 ComparisonComparison HPS spherical roller bearings demonstrate twice the operating life of conventional EA Series bearings for longer equipment operating life that lowers maintenance costs. Long operating life reduces maintenance cost HPS spherical roller bearings exhibit dramatically reduced cage wear at higher speeds over longer periods of operation. As a result, limiting speeds are increased to provide greater fl exibility across an extensive range of applications. High-speed, long-term operability provides increased fl exibility across a wide range of applications.

Innovative design developed through enhanced structural analysis 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 confi guration facilitates the placement of additional, larger rollers. Optimized design for the internal specifi cations 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. Adoption of state-of-the-art materials HPS spherical roller bearings are made from NSK’s high- cleanliness 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. Cage design features stronger resistance to wear By utilizing the space gained from eliminating the guide ring and improving the design through advanced 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.
