New, Larger Size Hps Spherical Roller Bearings Offer 25% Higher Dynamic Load Ratings Than Conventional Srb.

The improved wear resistance of the new larger size HPS bearings, under high speeds and high mechanical loads, enables them to cope with all types of demanding applications in a wide range of equipment types. Typically, these include pumps and compressors, cranes and other hoisting devices, paper machines, mining and extraction equipment technology, and conveyors and table rollers in the steel industry.

Designated as the CAM series, the larger size HPS bearings differ in design from the existing HPS- EA range of SRB (up to 130mm bore), due to the increased demands placed upon them. They are equipped with a guide ring, giving extremely precise roller guiding, and optimised solid brass retainers, which carry higher loads and offer very high wear resistance. In the smaller size EA series these features are achieved through a special surface treatment of the bearing steel plate retainers.

The optimised design features integrated into the HPS- CAM series not only increase the life span and the wear resistance of the bearings; they also increase the dynamic load rating by up to 25%. As a result, the larger size HPS units can allow down-sizing in high loaded drive assemblies for demanding applications, providing both space and cost savings for users.
