In order to get the low friction torque, bearing high rigidity, good rotation accuracy, use the small diameter of steel balls. The use of hollow shaft, ensure the lightweight and wiring of space. This type of bearings realized the extremely thin thin cross section of the bearing, realizing the products of miniaturization, lightweight. The diversity of products extended its usage scope.
6700, 6800 ,6900,16000 series thin-walled type, there are all kinds of dust cover form, with flanged form, stainless steel form, such as wide form, the variety is complete.
