An SPX Process Equipment Operation LIGHTNIN has developed a new state-of-the-art patented bearing for the MBI Mixer that will revolutionize the bottom entry mixer market. This design maximizes bearing life and minimizes particulate generation. All materials are USP Class VI certified. The patented all ceramic, dry running bearings require no lubrication. > Dry running Silicon nitride balls Retrofit to existing installed MBI mixers Silicon nitride inner and outer races Extensive testing both wet and dry running has proven this bearing will run in excess of 2000 hours under normal operating conditions PEEK Classicή for retainer material Long bearing life Minimum particulate generation (particulate test reports available) >
