Super Ball Bushing BearingSuper Ball Bushing Bearing ProductsPhone: 1-800-554-8466Website: www.thomsonballbushing.comFigure 1The Super Ball Bushing* bearing hasbeen the industry standard for selfaligninglinear bearings for over twentyyears. This bearing provides threetimes the load capacity or 27 timesthe travel life of conventional linearbearings. This dramatic improvementin bearing performance significantlyreduces downtime and maintenance,while increasing machine reliability.Thomson Industries, Inc. invented theSuper Ball Bushing bearing with manyunique design features. Besides thedramatic increase in load capacity,the Super Ball Bushing bearing is selfaligning,light weight and adjustablewith a low coefficient of friction(Figure 1).Figure 2BearingPlate60 CaseLinearRaceFigure 3BearingPlateBallsThree Times the Load CapacityThe bearing plates are hardened,bearing quality steel with ballconforming grooves (Figure 2). Thegroove is slightly larger than the balldiameter, providing an optimal areafor ball contact. The greater ball tobearing plate contact provides theincrease in load capacity or travel life.Zero Clearance FitThe bearing plates are also designedto float radially (Figure 3). When thebearing is mounted in an adjustablehousing, selected fit-ups can beachieved on the 60 Case* LinearRace*(shaft).Figure 4Cross-Section of Super Ball Bushing Bearing0.5º60 CaseLinearRaceSelf-AligningThe Super Ball Bushing bearing platespivot .5º about their centers (Figure 4)to assure smooth entry and exit of theprecision bearing balls. Each platealigns itself automatically tocompensate for inaccurate housingbore alignment, base flatness orcarriage machining. This providesuniform ball loading, smooth ballrecirculation and a constantcoefficient of friction.Smooth, Quiet OperationThe Super Ball Bushing bearing’souter sleeve and retainer are made ofwear-resistant, low-friction engineeringpolymer. It reduces inertia andoperating noise levels significantly.Page 38©2003 Danaher Motion. Printed in the U.S.A.
