Super Smart Ball Bushing® Linear bearings, already available in U.S. Inch and European Metric models, are now available in Japanese Industrial Standard (JIS) sizes. This advanced technology provides up to six times the load capacity or 216 times the travel life of conventional linear bearings. Users can minimize machine downtime and reduce machine costs. The product has coefficients of friction as low as 0.001 for ultra-smooth operation and deliver reliable performance at steady state speeds up to 3 m/s and acceleration up to 150 m/s2. Double lip integral wipers keep contaminants out and lubrication in, further maximizing product life.
