FRB BEARING Cross Roller Ring is a bearing with rollers arrange in vertical directions crossly among inside and outside ring of bearing.Roller contacts with roller pass by line, with good rigidity.Elastic deformation of bearing load is very little.And bearing can bear radial load, axial load, and torque load at the same time, especially applies to occasion requires high rigidity and high rotating precision.Using this bearing can simplify design and shorten shaft.The bearing is applied well in fields of robot and medical equipment.
