4 1 Linear Bearing General Information 1-1 Characteristics of HIWIN Linear Bearing HIWIN linear bearings enable high precision linear motion on round shafts by utilizing recirculating ball pathways. The patented recirculation curve enables HIWIN s linear bearing to sustain heavy loads with low noise and high stiffness. HIWIN s diverse line of linear bearings perform under almost any environmental conditions and load capacities to satisfy a wide range of applications. 1-2 Description JB F L 25 A WW Wiper Code Description Code Description JU UB Japanese Spec.
