SKF launches pioneering bearing rating life model
The SKF EnCompass Field Performance Program has launched with development of a pioneering new rolling bearing rating life model, optimized versions of four existing product lines, and innovative software tools to help predict and optimize the performance of bearing arrangements while in real-world service.
The new SKF Generalized Bearing Life Model has been created to help design engineers calculate a more realistic bearing rating life by considering more influencing factors than ever before. The model – built on the strengths of the current model developed by SKF more than 25 years ago and currently ISO-standardized worldwide – enables OEMs and end-users to more closely match bearings to actual application conditions.
For the first time the model encompasses more of the factors affecting anticipated bearing life, SKF says. The model separates surface from sub-surface failure modes and expands the range of performance parameters, including those for lubrication, contamination, surface strength, and mild-wear resistance.
SKF has further addressed improved bearing performance in the field by optimizing four existing product lines: SKF Explorer sealed spherical roller bearings, SKF Energy Efficient deep groove ball bearings, SKF Energy Efficient Y-bearings and units, and SKF Explorer steel/steel plain bearings.
Depending on the line, improvements include new designs, reductions in weight and friction, surface finishes and heat treatment, ready-to-mount unit assemblies, and advances in lubrication and sealing systems, among other innovations.
The newly introduced software calculation tools can help customers improve bearing arrangement design and select the most appropriate bearing for an application and conditions. These proprietary bearing simulation software programs – SimPro Quick and SimPro Expert – account for shaft, housing, bearings, external forces, and gear loads in calculations to arrive at the ideal bearing for the job.
